    Have ISPConfig 3 running on fedora 21.
    Added config files.
    Squirrelmail working and can read/send messages as expected. Using imap is a different story tho - can not connect tunderbird to send/receive emails. Testing with telnet and openssl seem to give all correct responses. Can login, receive list.
    Some of the errors I managed to read from the journald when I try to connect thunderbird :
    Jul 24 15:35:52 xxxxxx postfix/smtpd[23722]: improper command pipelining after EHLO from xxxxxxxx: QUIT\r\n
    Jul 24 15:35:52 xxxxxx postfix/smtpd[23722]: disconnect from xxxxxxxx
    Is this related?

    This error is from SMTP, not IMAP, so probably not related. SquirrelMail is an IMAP email client, when it works then IMAP is working. Did you try to connect from thunderbird without encryption?

    When I put connection security from STARTTLS to NONE, I can read mails with Thunderbird so apparently the STARTTLS and SSL/TLS are not working correctly.
