Hi,

I would like to know which ports have to be open in the firewall
for a SuSE-IMAP2 server (mail/http/pop/imap-server).


#ssh only for some ip's
(ssh 22/tcp # SSH Remote Login Protocol)
# for all ip's
smtp 25/tcp mail # Simple Mail Transfer
http 80/tcp # World Wide Web HTTP
pop2 109/tcp # Post Office Protocol - Version 2
pop3 110/tcp # Post Office Protocol - Version 3
imap 143/tcp imap2 # Internet Message Access Protocol
imap3 220/tcp # Interactive Mail Access Protocol v3
https 443/tcp # http protocol over TLS/SSL
imap4-ssl 585/tcp # IMAP4+SSL (use 993 instead)
sshell 614/tcp # SSLshell
imaps 993/tcp # imap4 protocol over TLS/SSL
pop3s 995/tcp spop3 # pop3 protocol over TLS/SSL

More ports ?
Or can I close some of those ports ?

Bye,
Peer
