sendmail.smtp port 25 can only access in localhost

[frederick van targero]

i can send mail in localhost, (sendmail),
#nmap localhost|grep 25
it exist;
pop3 has been normal.

i can not access the same smtp port 25 in remote host, nmap themailserver|grep 25
nothing.

how to set the sendmail support smtp/pop3?

hi

Check your sendmail.cf file.
You can find O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

this Addr limit your access only from 127.0.0.1

If you build your mail server , you may want to change this line.

good luck
