I am getting "Connection to storage server failed." in roundcubemail.
On doing a google search If find:
http://help.directadmin.com/item.php?id=473
Which puts the problem at dovecot. I did get a dovecot update back on 3-5 and that would match to my one roundcube mail user complaining and the delays I am seeing with thunderbird and outlook users.
So with my setup, I am trying to figure what are the index files to delete. Say for myself, I am seeing:
/home/vmail/htt-consult.com/rgm/dovecot.index /home/vmail/htt-consult.com/rgm/dovecot.index.cache /home/vmail/htt-consult.com/rgm/dovecot.index.log /home/vmail/htt-consult.com/rgm/.Drafts/dovecot.index /home/vmail/htt-consult.com/rgm/.Drafts/dovecot.index.cache /home/vmail/htt-consult.com/rgm/.Drafts/dovecot.index.log /home/vmail/htt-consult.com/rgm/.Sent/dovecot.index /home/vmail/htt-consult.com/rgm/.Sent/dovecot.index.cache /home/vmail/htt-consult.com/rgm/.Sent/dovecot.index.log /home/vmail/htt-consult.com/rgm/.Spam/dovecot.index /home/vmail/htt-consult.com/rgm/.Spam/dovecot.index.cache /home/vmail/htt-consult.com/rgm/.Spam/dovecot.index.log /home/vmail/htt-consult.com/rgm/.Trash/dovecot.index /home/vmail/htt-consult.com/rgm/.Trash/dovecot.index.cache /home/vmail/htt-consult.com/rgm/.Trash/dovecot.index.log
Do I delete all of these? The index.cache files are quite large.
