This feature is must have, considering there's no outgoing spam filtering.

AY, Please consider implementing this feature asap. It is really a must have to relay over external outgoing spamfilter services. Any shared hosting server without this feature will get blacklisted in no-time.

Pls implemente it... this feature is very important. Thank you.

Please implement this feature. It would be a great help to us MSPs providing shared hosting/email environments for our customers.

https://help.comodo.com/topic-157-1-288-4540-.html will tell you how to add smart host for individual or whole email server

How is this still not implemented?

this would be great, new Law´s in germany wan´t you to Archiving your mails in a special way, and for this you will need this!

So in germany we have new Law´s about archiving our mail´s, so we need to do this.

So this feature would be great!!!

Since Microsoft has changed policy this is a huge gap. Lots of people cannot deliver mail anymore when on hosting providers like strato (and others).

I agree. It's a needed feature

It will be nice to have module which works as SMTP relay only for outgoing mails.
At the moment on Google Compute engine with Plesk there is no easy solution to use Plesk to send emails.

Yes please!

Hello Plesk Staff!
Whats with this feature? seems important. You want to be the best? Then you should consider such big features :)

This Request has several posts and a lot more people want this feature than visible here:

Similiar approach, smarthost is the answer: 37 votes

Another one, don't focus on mailpipe, just smarthost:
https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/4452075-mailpile-support-secure-mail-server-option

All together it should not be that difficult and timeconsuming to implement this into the GUI/DB since postfix has native support for smarthost, single one, exceptions, domainbased or even receipient based.
Local delivery should always be excluded to avoid sending loops.

This should not focus on one particular service provider, but smarthost settings general.

Please bring this as default to the plesk panel and not as an Extension as this is quite useful to all of us (who understand why one needs a smarthost).

I am able to set this up via CLI, but not every user is able to do so and this isn't update/upgrade save either.

Thanks guys!

Per domain would be really great!

This actually a very important thing to be able to do. But many Plesk users don't know what this means I guess.
Even beeing able to set a global smarthost via GUI (inkl. SMTP Access Credentials, Security Settings and Port) would help a lot.
Per Domain would be nice too!

This should be a Basic Feature since most People use Commercial spam-protection These days.

we are starting to get requests from the field from customers who wish to use a 3rd party spam filter system. This feature would help us stay automated as each of these requests must be implemented manually on the MTA, and complicates migrations across plesk nodes, and prevents our customers from reconfiguring their setting for this themselves.
the ui should enable plesk admins and customers to set domain and mailbox-level transport rules. Our web developers are wanting to force email addresses used for web form notifications to use outgoing filtering, while also asking that some of the other addresses not be filtered (ceo, marketing addresses, etc)

This would be a must!

This would be a must!
