Could this maybe be added as new feature? "Outgoing SMTP Setting"
It's pretty common in every email-app, no?

This feature is really needed. It usually makes no sense to add external IMAP accounts that will try to send through the primary SMTP server.

I absolutely agree. When configuring identities for an IMAP account you should be able to alter the SMTP settings for that specific identity. This would make the IMAP accounts feature a lot more useful.
Is there any news on this?

Plus one here, I don't understand why this feature isn't implemented, IMAP mail retrieval without the ability to send mail from this same account is useless. I'd love to see the ability for the user to set outgoing SMTP settings on new identities. What could be even better is the ability to configure some domains settings in sogo.conf for example.

The idea here would be to set SMTP settings for he user, something like an array : SOGoSMTPAccountsDomains = ((gmail.com, smtp.gmail.com:587, TLS, PLAIN), (yahoo.com, smtp.mail.yahoo.com:465, SSL, PLAiN), ...)
SOGo would recognize the domain part of user identity and use SMTP settings accordingly.

Is there any progress here?

Also a +1 for this

And another one, with this feature we could set multi-accounts securely.

Also again +1 for this feature! We need this! Important...

time to push

Yes, I am also still waiting on this.

Made an account just to +1 this as well.
Sogo is almost perfect for my use case, but is overshadowed by the fact that I cant send emails in the web interface from auxiliary email accounts.

It's been a year... pushing

Hi there, this will be discussed for next roadmap
