Using Postfix for incoming mail and external SMTP server for outgoing mail?

[Zachary Grimshaw]

Hello,

I was wondering if it's possible to use Postfix for incoming mail (to email accounts and forwarding addresses) and then use an external SMTP server when sending mail?

Would following these instructions work with Plesk's setup?

Any guidance would be appreciated.
