Dovecot modseq_hdr.log_offset too large (Plesk)

Tue, 25 Apr 2017 00:00:00 +0000

Another quick fix post!

Problem

A mailbox for a specific user was not receiving mail on a postfix & dovecot on a Plesk server which I managed. The following error messages were being shown in the mail log:

$ tail -f /var/log/maillog Apr 25 15:04:34 server01 dovecot: service=imap, user=dan@example.com, ip=[192.168.0.1]. Error: /var/qmail/mailnames/exampledomain.com/dan/Maildir/dovecot.index: modseq_hdr.log_offset too large

As you can see the the error is: “modseq_hdr.log_offset too large”.

I’m not sure what caused this (I think it’s related to the dovecot.index file becoming corrupted - but not 100% sure), but this quick solution fixed it.

Plesk "The component was not installed" for all services.

This is a really small blog post, but it’s an issue I wanted to share - so hopefully anyone who comes across this issue themselves can avoid the mistake I made!

Basically, we noticed that one of our older Plesk servers seemed to have lost basic functionality like editing DNS zones, or accessing PHPMyAdmin or Webmail.

When going to Tools & Settings > Server Components we noticed that next to all the services (components), there was the message “The component was not installed”.
