sendmail on a dynamic ip

anybody know how to set up sendmail on a dynamic ip? right now im using a dynds.org domain, i used to be able to run a mail server with it in windows, but i havent really found any useful info on doing it with linux yet

thanks for any help :)

what's this got to do with sendmail? i'm confused, sendmail runs irrelevant to the IP number. mine certainly does.

I have the same problem. I am also using dyndns. I cannot seem to send mail to my linux box at home. Everytime I do the mail is delayed and then sent back to me.
Does anyone know what might be the problem?

This is a message I found on a mailing list I am on. I did it and now I am receiving mail.

First you need to edit /etc/mail/sendmail.mc file and look for the line
below..
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
Take out the Addr=127.0.0.1 part (just delete that part), or put dnl and a
space in front of that whole line.

Then you need to run the command ..
m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

Then make sure /etc/mail/local-host-names file has the domains and aliases
that you want sendmail to accept email for.

Then you need to turn on pop3 via, chkconfig ipop3 on, so that you can use
pop3 to receive/send email.

Then service sendmail restart and see if that gets you going.
