It would be nice to have an external SMTP (smarthost) ability for a per-domain basis (most mail services have this)
We use this for external scanning, data leak prevention and more.
Can this be be done?
Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
Everyone, please continue voting for this feature if you consider it important.

I would like to request to add the function for PleskWEBUI for Enable/Disable Mail relay function from firstname.lastname@example.org to registered email address.
Several 3rd party vendors offer email filtering and email encryption. To use these services you have to setup the mail server to send through a 3rd party smarthost. This would be a nice feature. I see that there is a comment about manually doing this through Postfix. What about those people using Qmail and those whose use Plesk that do not have shell access.

You can do this with Postfix and Sender Dependent Relayhost Maps:
But would indeed be nice if Plesk allowed for this via panel.
I'm not sure that is more than an edge case though.
