Cannot send e-mail with Outlook 2003

[Eugen]

Hello.
I'm having problems with Outlook 2003, I can receive an e-mail but I can't
send one!
The Outgoing server requires authentication and I ticked that Options, still
I can't send. I'm using Symantec Endpoint Protection, I made firewall
exception for Outlook and for POP and SMTP ports, I disabled "Internet e-mail
Auto Protect" it didn't helped.
The funny thing that at work everything is working fine, but not at home, I
really don't know what to do else.
Here is Print Screen of the settings:

Waiting for a reply that would solve the issue, thank you in advance.

Hmm. The 1and1 help page I checked
(<http://www.faq.1and1.com/e_mail/set...ok_outlook_express_and_netscape_mail_/17.html>)
gives some troubleshooting tips. Did you try them?

Thank you Brian!
My ISP was blocking the SMTP port, so I changed it to 587 and everything is
working fine now

Thanks for the tip...

My ISP was blocking SMTP port 25, I changed it to 587 and now everything is
working fine.
