Greetings,
We've had a longstanding problem with emails not being copied to the Sent folder that seems to be a bug with various email clients (Thunderbird, TypeApp.)
I know that Dovecot has the option to use the Submission service to copy emails to Sent without using SMTP to do this.
Would this solve the problem we've seen over the years of emails not being copied to the Sent folder on various clients under certain (unknown) conditions?
I had the same issue some time ago, If I remember right, with submission the IMAP client needs to support some additional IMAP features which most clients currently don't do.
I did it the other way round - my clients send mails by smtp and a postfix milter script catches the mail on the mail server and copies it locally to the user's IMAP mailbox - the clients don't upload any sent mails by IMAP anymore.
Am using mailfromd as milter: https://puszcza.gnu.org.ua/software/mailfromd/

Thank you for your helpful response,
