Mail transfer OK but NO downloading

[ggouts]

Hi everybody,

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

Did you install ISPConfig? Which pop3 server do you use, the one mentioned in the howto or do you use dovecot?

No ISPConfig at all. As far as Dovecot is concerned I didn't touch it. I followed the step-by-step guide "The Perfect Setup - Fedora Core 4".
So my mail server is Postfix.
And by the way, when I create my OE user, I don't check this SSL options; if this can help you.

Thanks a lot

I've just noticed something: The Sent Items are OK; I mean that when I sent an email somewhere using this account, the mail sending process works fine! Except this, my message is also stored into "Sent Items" folder correctly. My only problem is when I try to receive my e-mails; OE doesn't understand that there are new e-mails for downloading....

Thanls a lot

Where did you see these newly arrived messages? In /var/spool/mail/ ?

Please post the output of

netstat -tap

What's in your mail log?

Never mind guys. I've just turned my server into SuSE 9.3 Professional following "The Perfect Setup - SuSE 9.3" and all works fine.
Thank you all however.
By the way I have a question:
1. Is there a way (step-by-step tutorial) to secure my server, because I don't know much about firewalls etc.
