Mail transfer OK but NO downloading
I' ve just finished my "Perfect Setup-Fedora Core 4", and I have a strange problem.
I created a user into the server named john for sending emails.
On a second machine I created a user into Outlook Express. When I send an email from gmail (or whatever), the mail goes to my server, but Outlook cannot download it.
I can see johns' email through Webmin, but Outlook doesn't download it (No error messages).
Is this problem related with Postfix or OE?
Sorry for my bad English; I'm from Greece.
Thanks a lot
