I just installed iRedMail on Ubuntu 12.04 lts, fresh install following the tutorial on their website. Everything functions well, including webmail, however sending mail over smtp (port 465) doesn't work at all and I also cannot telnet to the server on that port.
Here's the result of nmap:
rDNS record for xx.xx.xx.xx: xxxxxxxx Not shown: 991 closed ports PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 80/tcp open http 110/tcp open pop3 143/tcp open imap 443/tcp open https 587/tcp open submission 993/tcp open imaps 995/tcp open pop3s
I tried telling postfix to restart in the hope that smtp would appear on the above but no such luck.
Does anyone with more experience with this have any ideas? Thanks in advance.
edit: Note i have removed iptables for now so that can't be the issue.
