add imap to existing pop3 server

Hello all, i hope this is a simple step. i have a centos email server with 5.3 on it. we have used the pop3 server for many years without problems. i are needing to add imap on this server now (an apple thing), is this possible to just add and not redesign or rebuild the server? i am running dovecot on this server currently. it seems dovecong.conf shows imap in theprotocols but when i try to telnet, it will not connect. maybe it is something as simple as a port needing opened, not sure what i am looking at. built this thru a guide from the forum back when just pop3 (yeah, old) .

if someone could please help me or guide me in a corret direction to look i would really appreciate it.

thank you

ok, i have an update. looks like imap is in dovecot but the iptables is not letting me in. i added to the table as show below, but when i still cannot telnet into the imap. if i turn off iptables, i can telnet into using the imap port with no problem. what am i missing here. i have issued services iptables save and restarted services. still only can hit the imap if iptables is stopped. any help is appreciated.

Imap is port 143. I don't see that in your output.

i noticed that also and also port 993.

when i add these to the iptables in the etc/sysconfig using vi editor and restart iptables services, it still will not let me test with a telnet session, it will not connect, but when i shutdown iptables, i can telnet.

can ou give me the proper context on how to add to the iptables and whta may be hosing it up and not working correctly?

thank you.
