POP emails are being blocked Sending and Receiving
« on: February 22, 2015, 10:41:14 PM »
What would conflict with Avast 2015 so POP emails are blocked?  My IMAP account syncs fine. My ISP is Comcast, when I talked to them, they had me rebuild the account as IMAP like my other account, but this setup didn't work for my Comcast situation, so I went back to POP with it.

Emails will come through after a computer reboot, but after a while (this last time it was a couple of days). When the Mail Shield is turned off, the emails will come through, when I turned it back on, I would get a send/receive error again. I did this a few times to verify it was Avast.

The send error is “The server responded: 421 Cannot connect to SMTP server 2001:558:fe16:1b::16 (2001:558:fe16:1b::16:587), NB connect error 1460',” The receive error says “'Your server does not support the connection encryption type you have specified.”

Any ideas so I don’t have to keep the mail shield turned off?

Install the latest avast version.
Make sure you have imported the certificate to Outlook.

Sorry, that didn't help, thanks for the suggestion though. At first it was looking good, then it stopped working within a day. I still have to disable the mail shield to get it to work

Do you have all (security) updates for the OS and Outlook installed ?
Do you have avast 2015.10.2.2212 installed ?

Are you using ssl for the mail ?

I had version 2015.10.0.2208, and updated it to the beta version 2015.10.2.2212

All the updates from Microsoft have been applied

My email provider uses an encrypted connection (SSL)

I turned on the mail shield and since I don't see this behavior right away, I will have to give it some time and see if there is any difference in Outlook

Emails have stopped again, only lasted one day this time. If I reboot or disable the Mail Shield it works, Started Outlook in Safe mode with the same results - I didn't reboot when I did that though. I tried to change my Outlook settings so the server doesn't require and encrypted connection (SSL) and tried the connection type to auto, but that didn't seem to help, and tried to change the encrypted connection type to None from TLS, I changed it back.

I would start my computer in safe mode, but every time I reboot the computer works anyway, its like an ad-in is stopping it, I thought starting Outlook in Save mode would get around that. What settings on the computer could do that? Should I clear my browser, reset it (does it even matter?)

The other thing that it not done regularly is the iPhone is charged by the computer

I suggest to rule out certain things first.
Please follow the instructions, if it doesn't solve things no harm is done:

I have ran the malware scans and have attached their results. When doing so, I had to reboot so I can’t test it at this point to see if things have changed. I ran two different MalwareBytes scans, the first one is without checking for rootkits. Both are showing the same files that should have been deleted the first time I rebooted. I’ll keep you posted as to how this affects the emails

Nice clean log, no apparent reason for the e-mail to fail

Emails have stopped again. Would a Hijackthis or process monitor log help any? I did see one Error entry in the Event log that comes up randomly:

Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x485AB6A0B848.  The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

I'm not sure what's going on here, the computer has not been rebooted but I'm able to send/receive right now? It's be acting right for a few hours now. Do you think I should still do those steps you suggested, or wait till it stops again?
