*bump*

Have tried everything here and still no mail for me. So sad.

Perhaps Your Account Does Not Exist on Mail Server?
 

If the mail server is remote to the computer you log into, it needs to have a way of knowing who you are. What I do is the lazy way and just set up a user account with the same name and password as the one I log into on my main Linux box. Then I set up qpopper POP3 server on the same system as Postfix is running on, and I can connect to it and get email with the same username/password as I log into my Linux workstation on.

There may be more elegant methods as using a centralized logon system such as NIS+ or LDAP, but I have had time to learn either of those. Anothing alternative would be to try and setting the desitation as usersname@workstation_ip_address ( e.g. jsmith@10.0.0.2 ) and see if that works for you.

That's all I have as far as ideas go.

Wait a sec, I haven't read your whole thread, but you are running a service to allow you to retrieve emails, right? Your options are using a file-based client to read email directly from the mail file ( difficult unless you are running the client on the same system as the Postfix mail server ), running a POP3 or IMAP server to 'serve' the email files to a POP3 or IMAP client, and that is all I can think of for ya. You cannot retrieve delivered emails from Postfix, all it does is send email out, and accept delivery of incoming emails from other SMTP servers.

I hope something in the email clarified things for you.
