I setup a system following the Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 9.04) guide. When I sent a mail using the mailx command I received the mail just fine in squirrelmail. When I send mail from outside the system or by using fetchmail. All of the mail goes into /var/spool/mail Not sure what I have set up wrong. I have another system that is set up the same way that seems to work and I've compared the various configs but I cannot seem to locate where the problem is.
