We have a huge issue with Imunify blocking legitimate users.

For example,

There is an office with 10 people.
1 user is entering a password incorrectly, triggering:

Dovecot Invalid User Login Attempt.
Exim Auth failed
Dovecot brute force attack (multiple auth failures).

This 1 user then gets the entire office IP blocked and 9 other people can't get their mail.

cPHulk will actually block only the 1 offending mail user.

How can we solve this?

Good day,

Just want to check if anything regarding this issue has been addressed in 4.2.x ?

Hello Mauritz! Partially, it will be fixed in 4.4 release but major focus for SMTP traffic management is scheduled for 4.5 release.

how many years away is that?

when someone is asking for a time frame they are asking for dates, not roadmap version numbers. this is a problem that should never have existed in a first place. waiting 2 to 3 versions to get this fixed while pretty things like cosmetic changes to dashboards are getting coded is maddening .

Hello John, we're releasing v4.4 in September, version 4.5 in October.

Unfortunately, it's not just a cosmetic change, it requires specific improvement in the firewall component.

Thank you for your patience.
