Cheers,
can u check 2 things.
1st: if u r using firewall at u r linux box than do it like this way
check rule of output and forward chain related 25 or 110 port blocking.
2nd thing.. do A ) telnet yourispmailserverip.com 25 if u get any some
sendmail or banner
B) telnet yourispmailserverip.com 110 u will get SMTP is
running ..
in both u should get some screen things... but if u will get something like
trying to connec or connnection refused ... that it is some where else
block your ip to access that mail server. Call to your isp.(Make sure
u dont have any rule in your local Linux rule for SMTP/IMAP port
blocking Rule)
