Can not get outgoing SMTP to work (sending mail from my computer)

Dan Mikkelsen

Basic Pleskian
I can not for the likes of me get the server to send mail via smtp from my computer.

I have some clients who need to use their server as a mail sending server also through outlook/thunderbird and such, since they don't have their own ISP to use.

I have tried with thunderbird myself, and it never seems to work. On port 25 it is just timing out. On port 587 it is not connecting.

I create an email with password, and try to use this as the sender login.
I have tried with both mailbox switched on and off.
In the PLESK's mail configurations relay is set to SMTP with authorization required.

I have disabled my antivirus when trying this, as this sometimes redirects to different ports

Anybody have some other stuff i can try?
