M-x vm-mail-send-and-exit not using sendmail

[Lynn David Newton]

For the first time in my 21-year Unix experience I am
using a system that uses Postfix rather than sendmail
to deliver mail. (SuSe Linux 9.1 with xemacs 21.4 patch
15) Therefore, I don't know how to ship mail off the
system, since it's my understanding that by default M-x
vm-mail-send-and-exit delivers mail through sendmail.

I don't really know where to start fixing that problem,
and realize there is probably some Linux side work to
be done, which I though I did, using the YaST2
interface, but there is probably more to it.

Can someone help me get back on track? Meanwhile, I'm
able to receive mail just fine, but I have to send mail
using MS Entourage on my Mac.

Thank you.
