I've installed SuSE 8.2 with a program that requires /usr/lib/sendmail to send email. So I have to start postfix on that machine. But it also starts SMTP - and I don't want that! Isn't it possible to just have let it send email? Commenting out smtp from master.cf stops all outgoing email as well. -- Kaare Rasmussen --Linux, spil,-- Tlf: 3816 2582 Kaki Data tshirts, merchandize Fax: 3816 2501 Howitzvej 75 Åben 12.00-18.00 Email: kar@kakidata.dk 2000 Frederiksberg Lørdag 12.00-16.00 Web: www.suse.dk

Uhhh sending email is done using the smtp protocol. So if you don't have it, no mail gets sent. What you don't want is outsiders getting into your machine using smtp protocol, and that's the job of a firewall. Nothing wrong with running smtp internally to your network/machine. -- +----------------------------------------------------------------------------+ + Bruce S.

So with postfix, usera@localhost sending email to userb@localhost will do this with smtp ?? Maybe I should install sendmail instead. -- Kaare Rasmussen --Linux, spil,-- Tlf: 3816 2582 Kaki Data tshirts, merchandize Fax: 3816 2501 Howitzvej 75 Åben 12.00-18.00 Email: kar@kakidata.dk 2000 Frederiksberg Lørdag 12.00-16.00 Web: www.suse.dk

usera@localhost sending email to another.user@another.domain requires smtp on localhost ?? -- Kaare Rasmussen --Linux, spil,-- Tlf: 3816 2582 Kaki Data tshirts, merchandize Fax: 3816 2501 Howitzvej 75 Åben 12.00-18.00 Email: kar@kakidata.dk 2000 Frederiksberg Lørdag 12.00-16.00 Web: www.suse.dk

The sendmail command would be the local delivery agent, but it would not use tcp/ip to do so. It would just plunk the mail into the proper spot.

There's an unnecessary open port. There's an unnecessary process. -- Kaare Rasmussen --Linux, spil,-- Tlf: 3816 2582 Kaki Data tshirts, merchandize Fax: 3816 2501 Howitzvej 75 Åben 12.00-18.00 Email: kar@kakidata.dk 2000 Frederiksberg Lørdag 12.00-16.00 Web: www.suse.dk

Only open (to the internet) if you allow it to be.

Only while an email is being sent... It's a dirty job, but someone has to do it. (that is, some program would have to do the sending) I think you're running on the wrong assumptions about smtp. -- +----------------------------------------------------------------------------+ + Bruce S.

Not unless you tell it to listen to the internet device. If you forget, as you will be running a Firewall (which you should in any case), this will not allow connections to it - unless, again, if you open it explicitly.
There's an unnecessary process.
Yo can configure it in Yast for "no permanent network connection" in which case it will not be up till you call sendmail manually. Of course, this means that internal mail will not work (no local smtp), and that if the outgoing mail can't be sent for some reason, it might not retry, and you might not know it - because the process dies. In any case, a process that is not doing anything is swapped out if the memory is needed. -- Cheers, Carlos Robinson

Yes, sendmail would be called, but it would just deliver the mail. No tcp/ip needed. And postfix has its own 'sendmail' command so there's no need to install sendmail. -- +----------------------------------------------------------------------------+ + Bruce S.
