Hi I set up iredmail today, and am having a roundcube/dovecot/imap related problem.

I suspect it is more dovecot related than roundcube, but the behaviour is displayed when you try and log into roundcube when you get the error message: Connection to IMAP server failed.

The message in the logs are as follows:

Apr 18 10:34:02 auth-worker(2679): Info: mysql(127.0.0.1): Connected to database vmail

I have chowned the directory to vmail and chmod u+w the directories recursively. I have created the directories that are mentioned in the error message.

Directory /var/vmail should be owned by user/group: vmail:vmail. But yours is owned by different user (uid/gid: 5000:5000). You can fix it with below command:

# chown -R vmail:vmail /var/vmail

Hi ZhangHuangbin.

I did do that and that did not resolve the problem unfortunately.

Could you please show me output of below commands:

# id vmail
# ls -dl /var/vmail
# ls -dl /var/vmail/vmail1
# dovecot -n

Re: Roundcube failure to connect to imap server

Hey.

I somehow borked my whole install while troubleshooting iredmail, and rolled back to this morning before I installed to restore at least web service.

I'll play around a bit and let you know after I installed from scratch.

Regards

Hey Zhang,

Just want to say thank you -- I was having a similar issue after restoring vmail from a backup.  Your post helped me to get it cleared up.
