i am trying to set up a mail server for the company i work for , however i ain't expert in linux
been trying to set the mail up for days and so far only manage to send mail but no success in receiving any
the MTA i am using is postfix , whereas for the POP , IMAP or SMTP , i don really understand but using chkconfig to check it seems like the POP3S, IMAPS are on , as for SMTP dunno about it but i heard it comes with POSTFIX .
i 've tried to telnet to localhost 25 from the terminal and it responsed, but when i tried it on the browser http://localhost:25 , it gave me some reply about the port has been disabled for security reason.
please correct me if i am wrong
i then set the port 25 to be opened in the firewall using
'iptables -A INPUT -p tcp --dport 25 -j ACCEPT'
after that i can receive mail from the outside(from yahoo.com) but will this post a security threat since i have heard that port 25 is not a safe port? are there any other ports to replace this one? please enlight me on these
Flibble , thanks for your reply
i think i might have set my MX record correctly , anyway is there any way for me to check it ?
maybe from certain files?
err cannot find the files you mention except the one in main.cf which i have posted at the start of this thread
by the way i just found out that i can only send and receive mail using pine,
i tried to configure evolutions with setting : receiving mail (pop.company.com) and sending mail (mail.company.com) but it did not work , maybe i misconfigured evolutions or the postfix main.cf files. any hints on these please thanks
nb: my main.cf is posted at the start of this thread
