Change port for sendmail smarthost

[Marc UBM Bocklet]

Hello everybody! :-)

I've googled around and looked at www.sendmail.org and the handbook, but
was unable to find anything regarding that subject.

My problem is that the smtp-server at my sendmail smarthost is
listening on port 697 instead of 25 and i need a way to tell sendmail
that.

I experimentally tried 

define(`SMART_HOST', `smtp-server.com:697')

but that didn't work.

Any help is appreciated :-)

Bye
Marc
