This has probably been asked before but...
I have a SuSE MailServerII setup with Postfix etc...
Everything works fine and users can dial up their own ISP from home and then use StarOffice IMAP client to access their email across the net and syncronise mail...
But I need them to be able to relay mail (at the moment they can only send to the local domain (if they are outside)

SMTP-AUTH ? TLS ? help !?

Thanks in advance,
Malcolm.

Ps. How hackable is this config ? Can I set up password lockout after n attempts ?

SMTP AUTH would probably be the easiest to implement, but I don't know if StarOffice email can do authentication to an SMTP server (Netscape, Mozilla, evoloution, etc., can do SMTP authentication). You'll need to have Cyrus SASL installed and your sendmail needs to have been compiled with SASL support. I know that the sendmail furnished with late versions of RedHat includes SASL support, but I don't know about SuSE. You should be able to tell if SASL is available by looking for libsasl* and/or the presence of saslpasswd. And you ought to be able to tell if sendmail supports it by looking at the libraries with 'ldd /path-to/sendmail'.

I find that the best way to use SASL is to use sasldb and enter the usernames and passwords into the SASL database. Lot's of folks seem to have problems when they try to use the system password files. If you haven't seen it, there's a pretty good discussion of how to set up SMTP AUTH at http://www.sendmail.org/~ca/email/auth.html
