Separate Incoming IMAP and Outgoing SMTP Servers?

Initial setup
1

I’m still using Postbox, thinking about moving to eMClient.

I use gmail for incoming IMAP but use Amazon SES for outgoing mail. This was a showstopper to using EM Client before… is this possible nowadays?

Thanks.

No the SMTP server address is still automatically specified to Gmail in the automatic account wizard.

There is a Sleekplan suggestion you can vote for that feature with OAuth token login access.
