I have been using avast 4.7 for a few months. I've had to reinstall it once. Avast worked great for serveral months but lately it is interfearring with my outlook express 6.0. It is stopping me from sending mail out, receiving mail seems to be just fine. If I shut down avast my outlook express works fine. I don't have the mail protection wizard in start/all programs/avast/avast antivirus. It look like everything downloaded ok at the time but I'm not sure. How can I correct this problem? I've been doing google searches for 2 days now and would love to get avast and outlook express working together again. Thanks in advance

avast doesn't stop you sending out email,it scans content and will alert you to infected traffic, but not block/stop.
What version of avast do you have ?
The latest is 4.7.844, check the about avast for details.
Do you have a firewall if so what ?
What is your Operating System ?
You only have the mail protection wizard if you don't have XP or other NT based OS.
What errors or warnings are you getting when you can't send email ?
What type of email is it, with attachments, large size, etc. or is it every outgoing email ?
-
Thank you for the reply
It is the latest version 4.7.844
I use windows firewall. I've been usuing for long time and it did work with avast in the beginning months.
I do use xp with respect to mail protection wizard.
I've received different error messages as I seem to fix one error to only receive another. However, the main error messages that I get are 0x800ccc78, 0x800ccc7d, 0x800ccc90. While trying to repair these messages I've also get 0x800ccc0e, 0x800420c8, 0x800ccc0d & 0x800ccc7c.
As you can see I've been going in circles trying to correct the problems. If I turn off internet mail I'm able to send.
It is all outgoing email regardless of size, including replys.
I hope this info helps to solve this. Thanks

Well these errors don't seem related to any avast errors.
When you try to send emails what is the full text of the error message or post a screen shot as these errors in isolation aren't very helpful.
-
The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was .*********** Subject 'Re: maybe now', Account: 'pophm.sympatico.ca', Server: 'smtphm.sympatico.ca', Protocol: SMTP, Server Response: ******* Must issue a STARTTLS command first', Port: 25, Secure(SSL): No, Server Error: 530, Error Number: 0x800CCC78
The server responded with an error. Account: 'pophm.sympatico.ca', Server: 'pophm.sympatico.ca', Protocol: POP3, Server Response: '-ERR Cannot connect to POP server ************(********:110), connect error 10060', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC90
I deleted some identifing info but this is what I'm running into.

Unfortunately, I suspect that avast is the cause of the problem here.
Since one of the server responses is:
Must issue a STARTTLS command first
then it is telling us that the server expects this mail transfer to be on a secure link. It has also been reported before in this forum that sympatico.ca is now requiring email connections to be secure.
It is unusual (but not unknown) for mail servers to use port 25 for a secure SMTP connection. avast does not expect the standard port 25 to be used for a secure SMTP connection and does not gracefully get out of the way and prevents the connection from being made.
You do not need to turn off the Internet Mail scanner completely but to make the sympatico.ca SMTP connection work you will need to turn off the scanning of outgoing mail completely (Internet Mail scanner > Customize > SMTP tab > uncheck "Scan outgoing mail"). This is not really a significant loss of functionality for you since the whole point of a secure connection is to prevent it from being scanned by anyone and anything (including antivirus programs).
See this thread for an earlier discussion on this topic:

Thank you guys for trying to help me out solve this.
alanrf I've read the other form you linked here. Forgive my ignorance, but would stunnel work in my case? or
if I was to change isp solve the problem?
To what I have read port 25 is a standard smpt connection.
-
Changing ISP could possibly resolve this but it is a severe option, if you have no other issues with sympatico, you would need to confirm if they used secure email also.
You are correct port 25 is for standard SMTP connections and for secure email communication SSL/TLS the usual (standards) port would be 587.
STunnel is fine for acting as a third party interface so avast can scan encrypted emails like SSL/TLS when secure communication is used. However, you would still be in the same position because of the use of port 25 for secure traffic, avast would still try to intercept it and scan it.
See http://en.wikipedia.org/wiki/Transport_Layer_Security
While an increasing number of client and server products can support SSL natively, many still do not. In these cases, a user may wish to use standalone SSL products like Stunnel to provide encryption. However, the Internet Engineering Task Force recommended in 1997 that application protocols offer a way to upgrade to TLS from a plaintext connection, rather than use a separate port for encrypted communications - this prevents use of wrappers such as Stunnel.
This is effectively what you are seeing, the ability to switch standard ports for encrypted traffic.
-
Thanks DavidR, changing isp is not an severe option for me to do since sympatico announced they will start readin emails. (alittle invasive for my preferrences)Nothing like giving me a reason to change.
However, I would like to make sure avast will scan regardless which isp I end up using.
I do prefer avast over norton (my previous av) so I would like to try and resolve the problem if possible.
What I don't understand is why avast was working prefectly for serveral months and all of sudden I'm getting this problem? Thanks
-
However, I would like to make sure avast will scan regardless which isp I end up using.
avast shouldn't be influenced by the ISP... I have changed my ISP recently, I have emails on 4 different servers... no problem with scanning and avast.
Stunnel is needed only if the email server requires SSL communication (like GMail, for instance) 8)

Was there something in the recent new version that could cause this problem?

Which version are you using and which one you have before? I think there weren't significant changes on mail scanner to bring any trouble, really...
Sorry to ask again, but too many posts to read and mail scanner is not my knowledge are, but which is exactly your problem now?

I'm using 4.7.844 now, I would have used the previous version from your site.
The problem I'm having is avast seems to be infearring with my out going messages only in outlook express.
The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was .*********** Subject 'Re: maybe now', Account: 'pophm.sympatico.ca', Server: 'smtphm.sympatico.ca', Protocol: SMTP, Server Response: ******* Must issue a STARTTLS command first', Port: 25, Secure(SSL): No, Server Error: 530, Error Number: 0x800CCC78

From THEIR site. I'm an user like you 8)
Must issue a STARTTLS command first ... Secure(SSL): No
Does sympatico use TLS encryption to send mail?
Server Error: 530, Error Number: 0x800CCC78
Error: 0x800CCC90, Error Number: 0x800CCC90
Did you Google this? I mean, the error numbers?

I don't know for sure what they use and yes I've been googling error codes for 3 days now. As I stated earlier, I seem to be at a point where I'm going in circles. Thanks

The something that has changed is not, I think, avast since this issue existed (and I tested it) 5 months ago.
I just found this posting in broadband reports:
This is a copy/paste from sympatico's forum:
The Incoming Server (SMTP) Settings need to be as follows:
Server Name: pophm.sympatico.ca
Port: 995
Check "Use name and Password"
User Name: youremail@sympatico.ca
Use secure connection: TLS
The Outgoing Server (SMTP) Settings need to be as follows:
Server Name: smtphm.sympatico.ca
Port: 25
Check "Use name and Password"
User Name: youremail@sympatico.ca
Use secure connection: TLS
Also, as Glen1 mentioned, turn off any email protection you may have in any anti-virus app you have, most email scanners won't work with ssl (encrypted) email. This will cause issues.
Also, I have heard smtphm port will use port 587 as well as port 25. Though i never tried it.
Yes, it is true that port 25 is the standard smtp port but there is no law that says an isp cannot choose to use it for secure SMTP and we also see it being done in the thread I linked.
Are you using port 995 on the incoming (POP3) side for your account in OE?
It may well be worth checking to see if mail is successfully delivered if the SMTP port is set for the account in OE to 587 which is now a well known port for secure mail sending (we have seen at least one other case in the forum where the secure SMTP traffic could be sent on port 25 or 587).
Remember that mail received or sent on a secure mail connection cannot be scanned by the Internet Mail scanner so you would be relying on scanning provided by the isp. To scan on the receive and send side by the avast Internet Mail scanner would require the use of STunnel. There will be no issues with it if port 587 can be used for sending your sympatico mail.
The only complication that might arise would be a problem of multiple email accounts where one wanted to send standard SMTP on port 25 and another account wanted to send secure SMTP also on port 25.
[Edited] to correct port number typo error.

Thanks alanrf, I did follow your advice from a earlier post in shutting down the outgoing mail scanner only and I am able to send now. I would have prefered not to customized any scanners but I do need my smtp working.
I did check my pop3 setting and it was at 110. I was receiving incoming mail at that port with no issues including avast's confirmation email when I registered for these forums. I did change it to 995 and made it ssl just in case.
I do like the avast av over the norton so I hope this will be the last of my troubles.
I am still curious why avast worked great for serveral months and all of a sudden started acting up last week? I would love to hear your thoughts of what went wrong.
Thanks all, your help was very much appreciated. Cheers!
-
This is a follow up question. I followed another suggestion from one of the other avast forums and did a scan with ewido 4.0 and found a trojan in my sympatico program files called Trojan.NoClose.i
Could this have been the root of the problem? I would prefer to turn back on my outgoing mail scanner if possible. Thanks in advance once again!
-
I don't think it was the cause of the problem, that is as Alan has explained avast not being able to scan secure email and not being able to handle the STARTTLS, or rather once seeing this let the email pass without scanning.
However, I would suggest that you confirm the detection is correct. What was the file name, where was it found example (C:\windows\system32\infected-file-name.xxx) ?
You could also check the offending/suspect file at: Jotti - Multi engine on-line virus scanner (http://virusscan.jotti.org/) if any other scanners here detect them it is less likely to be a false positive. You can't do this with the file in the chest, you will need to move it out.
Or VirusTotal - Multi engine on-line virus scanner (http://www.virustotal.com/xhtml/index_en.html)
If it is indeed a false positive, add it to the exclusions lists (Standard Shield, Customize, Advanced and Program Settings, Exclusions) and check scan it periodically using the ashQuick scan (right click scan), when it is no longer detected then remove it from the exclusions.

Thanks DavidR, I was quick to delete the trojan so I do not know the exact path. It was something like c:/program files/sympatico/user/
I do not remember the balance. It was ewido that found it along with some medium risk tracking cookies and not avast.
I appreciate your info with respect to jotti. I had not heard of that one before, thanks!
-
In Ewido there is an icon, Infections, click that it should retain some information about it and give the ability to Restore or Finally delete, wait at least two weeks to do that, this ensures no harmful effect of the deletion, etc.
-
Thanks, that is good advice. I guess that is a tip I'll have to remember next time. I had clicked remove infections with respect to the above mentioned trojan. Then I clicked ok to confirm removal. :-[ Sympatico does have a good support network if it ends up being an important file. Cheers!
-
thank you had to reformat harddrive and reinstall all
kept getting outbound error messages only thing that works is to turn off outbound mail scanner in avast dont think it will hurt to not scan my own outbound mail
-
First I think you should have started a new topic for your problem rather than open on that is almost a year old, the email scanner has changed a number of times during that period.
I feel we should have been able to avoid a reformat and re=install, that really is a last resort.
Personally IMHO you would be ill advised not to scan your outbound email, I would go so far as to say set it to High sensitivity. This can provide early warning if you happen to have an undetected spambot trojan installed, multiple emails in a time period.
