Symptoms

After installing Imunify360, no users can log into Webmail and the following error can be seen in the mail log.

Error: imunify360: unsupported dovecot version found: 2.3.19.1

The following entrie also exists in /var/cpanel/templates/dovecot/main.local.

args = [% IF allow_domainowner_mail_pass %]dovecot_imunify_domainowner[% ELSE %]dovecot_imunify[% END %]

 

Description 

The PAM module of Imunify360 version 6.10.1 supports Dovecot version 2.3.18 instead of version 2.3.19.1, which is used on cPanel servers. Imunify360 has opened a case, DEF-22619, to correct this. 

 

Workaround

  1. Log into WHM as the 'root' user.
  2. Navigate to "Home / Plugins / Imunify360."
  3. Click the gear icon on the right side to open "Settings."
  4. On the "General" tab, scroll down to the "PAM" section.
  5. Deselect the "Exim+Dovecot brute-force attack protection" option.
  6. Click the "SAVE CHANGES" button.

Please note that DEF-22619 will be patched in Imunify360 version 6.11.
