Symptoms

Mail authentications aren't being saved in the tracker. The file is updating but empty.

file /etc/recent_authed_mail_ips
/etc/recent_authed_mail_ips: empty

Exim ACLs that rely on the tracker may also reject emails.

hostlist recent_authed_mail_ips = net-iplsearch;/etc/recent_authed_mail_ips

 

Description

Dovecot 2.4 changes how logged-in users are presented in the logs. This information is used by the recently authenticated mail IP tracker in Tailwatchd. The tracker ensures that logged-in users are automatically trusted for other functions in Exim where the IP is being tracked. The syntax change in the mail log prevents this functionality from being used. Some users who rely on this hostlist in an ACL may find that some emails are rejected.

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-50725. Follow this article to receive an email notification when a solution is published in the product.
