postqueue will show the current contents of the various queues. The maillog file will show a record of everything that has happened to each message. > Both qmail and postfix have modules to serve mail boxes using POP3 so > no problems here No idea about qmail, but postfix doesn't do POP.

Yes. You can route all your outbound mail via a specific relayhost: See: http://www.postfix.org/postconf.5.html#relayhost Note that there is no "bagging" (archiving, packaging, etc.) involved. Messages are sent according to the SMTP protocol. > However the mail provider my company is using has blocked access to > the SMTP server only to authenticated users, and sat provider doesn't > give SMTP services... Get permission to relay through the server you want to use and configure SMTP auth. The company that runs the server you're relaying through will supply the needed credentials. While it is possible to configure postfix to connect as a specific user, this isn't worth the time involved since it will work only until the ISP discovers what you're doing.
