Hi I have just moved from a Fedora server using Dovecot, to Debian 6 with Courier. I'm having a problem connecting to IMAP on port 993. The server does not respond. I've tried everything I can think of, and I still cannot connect, so i'm hoping somebody can shed some light on this for me. The server was configuring using the Debian 6 ISPConfig3 Perfect Server setup. There are no useful errors in mail.log, only entries like these below: Code: Apr 1 23:15:01 server1 imapd: Connection, ip=[::ffff:127.0.0.1] Apr 1 23:15:01 server1 imapd: Disconnected, ip=[::ffff:127.0.0.1], time=0 Apr 1 23:15:01 server1 pop3d: Connection, ip=[::ffff:127.0.0.1] Apr 1 23:15:01 server1 pop3d: Disconnected, ip=[::ffff:127.0.0.1] netstat -an returns: Code: Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN tcp 0 0 192.168.1.10:53 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:953 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:55290 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:10024 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:3306 127.0.0.1:42812 ESTABLISHED tcp 0 0 127.0.0.1:3306 127.0.0.1:42806 ESTABLISHED tcp 0 0 127.0.0.1:42806 127.0.0.1:3306 ESTABLISHED tcp 0 0 127.0.0.1:42812 127.0.0.1:3306 ESTABLISHED tcp 0 0 192.168.1.10:22 90.202.203.187:49365 ESTABLISHED tcp6 0 0 :::143 :::* LISTEN tcp6 0 0 :::8080 :::* LISTEN tcp6 0 0 :::80 :::* LISTEN tcp6 0 0 :::8081 :::* LISTEN tcp6 0 0 :::53 :::* LISTEN tcp6 0 0 :::21 :::* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 ::1:953 :::* LISTEN tcp6 0 0 :::443 :::* LISTEN tcp6 0 0 :::993 :::* LISTEN tcp6 0 0 :::995 :::* LISTEN tcp6 0 0 :::110 :::* LISTEN tcp6 0 0 192.168.1.10:143 90.202.203.187:52854 ESTABLISHED netstat -tap | grep imap Code: tcp6 0 0 [::]:imap2 [::]:* LISTEN 12354/couriertcpd tcp6 0 0 [::]:imaps [::]:* LISTEN 21440/couriertcpd tcp6 0 0 server1.tgrsvr.co:imap2 5acacbbb.bb.sky.c:52854 ESTABLISHED 24761/imapd When I try: The server does not respond.

I have tried adding specific IPs (192.168.1.1,127.0.0.1) to the 'SSLADDRESS' field and restarting imap-ssl, but no joy. Please help! Thankyou.
