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 ?
