Avast block incoming email

Hello,

Since the recent update (I used Avast for several years without problems until then), I can no longer get my emails.
Disabling Avast agents solves the issue, so the cause is obvious.
I already tried to repair and even clean install Avast, no change.

What email client and ISP ???

What exact version of avast ?
What exact shield is causing the problem ?

The issue exists with all email clients I tested (outlook, live mail, thunderbird).
avast free 17.6.2310
What shield, not sure to understand. Can other agents than the mail one interfere with emails ?

If you’ve disabled the mail shield and the emails never sent, try disabling the Web Shield and post back.

The issue is with the mail shield - I can leave others enabled.

I know this may sound too simple, but have you tried shutting down router/modem for a minute or so and then rebooting? PC too.

Check if you have a proxy set or not, depending on the instructions from the mail provider.
Also check the settings for SSL/TLS scanning and make sure they are correct.

No proxy.
As for SSL parameters, not much to say - the box to scan can be checked or not, and I tried the export certificate feature too.

What email client ?
What exact os ?
What is the exact error message you’re getting ?

Hi antjac,

could you please send me content of mailshield.log file? It is located in C:\ProgramData\AVAST Software\Avast\log folder.

Also please try to turn off SSL scanning. Go to Settings > Components > Mailshield > SSL scanning and uncheck Scan SSL connections.

Thanks in advance,

It is the generic “cannot connect to server” error (see attachment).

What happens if you turn off SSL scanning ?
If that is not solving it, what happens if you don’t use IMap ?

As the log says, it also blocks POP servers.
I already tried without SSL.

Could be me, but I only see IMap on IPV6 address blocked.
What happens if you change your DNS to the one from Google ?
