Avast blocked all incoming mail on Outlook

[janell23]

Hi,
Starting on March 22, 2019,  I hadn't realized that I had 5 email accounts that were blocked by Avast in my Outlook account (on a MacBook Pro). I searched online not knowing why my incoming mail wasn't working (I could send from these accounts) and I saw that one person on a Mac Forum advised to disable Avast email protection. I did that and the emails immediately flowed in. These were all POP accounts and hosted on the same server (but all diffferent domain names). 

Did Avast do an upgrade on Friday that would cause this blocking? I would like to turn Avast back on, but can't until this blocking problem is fixed.

Thanks for your help.
Cheers,
Janell

Hello,
we will double check this, however there should not be any changes to pop3 scanning code, and our tests contain quite an extensive amount of pop3 scanning. Thanks for notifying us.
Kind regards,
Ondrej Kolacek

Thank you Ondrej, I very much appreciate the help.  If it was one account, but all of the emails would not load on my computer with Avast on, and I did get them on my iphone & ipad.

Was this resolved janell23?

[janell23]

No, not resolved. I just enabled the Mail  Shield, and I couldn't receive messages.  Turned it back off.

Thank you for the update, can you inform us who is the email provider? You mention Outlook, are you using Outlook for Mac as the email client? Also when you can not receive messages, do you get any errors in the email client?

[janell23]

H Mac,
Yes, Outlook as part of Microsoft Office 2011 on a MacBook Pro.  I get no warnings as to the failure, the emails just do not show up.  Fortunately, I have one of those email addresses on my IPad, so noticed I wasn't getting them on my Mac. I have a reseller server account with Hostgator, and it was pretty much all of those website accounts on my server whose emails ALL failed. Could it be something to do with that server and IP that got onto some sort of black list that Avast listed in their algorithms and that is why I can't receive emails?  I know websites, emails not so much. :-( 
Thanks so much for your help and interest in this!

If only hostgator is affected, lets try to set an exclusion for the hostgator servers. See the section "Exclude mail servers from scanning" on this link and add your hostgator server(s) to the excluded list to see if this does solve the issue.

Hello,
we were not able to reproduce the issue, however we do not have hostgator accounts available. Please send us a support package (https://support.avast.com/en-ww/article/Submit-Mac-Security-support-file); in description please mention this thread. There may be something in logs.
Kind regards,

janell23, what is the version of your product and virus definitions?

[janell23]

Lukas,  Avast Security: Verson 13.12  Virus Definition version: 19040906.

Ondrej, I did send in the support package file.

Mac, I put those exclusions in then tested it, and the emails worked.  Thank you so much!

Thanks all!
Cheers,
Janell

I have a similar issue with the latest update of Avast
outlook displays an error code 0x800ccc1a and email cannot be sent or received.
disabling Abast resolves the problem
I reported the problem to Avast bud did not get any reply
