I have redhat 7.3 installed on my server. I have DNS and Apache setup. Using Postfix for SMTP. And UW IMAP for IMAP/Pop3. I am able to log into SquirrelMail and view my mail. When I compose a new message and send it; nothing shows up in the sent items folder; and the message never goes thru. I do not get a return response either. It just disappears like it was never created. I have checked the squirrelmail settings everything seems to be configured correctly. I have running Outlook Express on a desktop system on the network and have no problems sending or receiving mail. Help would be appreciated.... i am completely stumped. I have tried google and google groups with no luck.
