The following error messages were being shown in the mail log:</p> <p>$ tail -f /var/log/maillog Apr 25 15:04:34 server01 dovecot: service=imap, <a href="mailto:user=dan@example.com">user=dan@example.com</a>, ip=[192.168.0.1]. Error: /var/qmail/mailnames/exampledomain.com/dan/Maildir/dovecot.index: modseq_hdr.log_offset too large</p> <p>As you can see the the error is: &ldquo;modseq_hdr.log_offset too large&rdquo;.</p> <p>I&rsquo;m not sure what caused this (I think it&rsquo;s related to the dovecot.index file becoming corrupted - but not 100% sure), but this quick solution fixed it.</p>
