When I send something out via outlook it gets rejected and this is the response What MTA does SuSE OpenExchange uses? Postfix I'm guessing. Will your Outlook users always connect from the same IP? Are they on an internal network will you want to allow them to check with Outlook from anywhere in the world? Webmail works because the MTA sees the connection as coming from localhost because the connection is made from the web server running on the SuSE box. By default, most MTA's are configured to not relay mail when any old Joe from the Internet connects on the SMTP port. This is a good thing because of all the stupid spammers in the world nowadays. To allow SMTP relaying for your legitimate roaming users you will need to configure your mail transfer agent (it's definately not a Samba problem!) You can either set up authenticated SMTP or something like POP/IMAP after SMTP. The latter means that SMTP is allowed but only after the user authenticates via POP or IMAP (When Outlook sends the username/password to the server). I use POP/IMAP after SMTP on a qmail MTA running on SuSE 8.1 though, though it's kind of an ugly solution to this problem. Authenticated SMTP is probably the better choice. Since qmail is most definately not the MTA on your OpenExchange server, hopefully someone else on the list will be able to point you into the right direction for your MTA.
