I use Mailcow so that my applications can send mails via SMTP. This works fine and is well documented.
However, these mails do not appear under “Sent”.
Can I somehow enable or force these mails to show up under “Sent”? With Gmail this had worked.
That’'s usually someting the client does via IMAP. However Gmail seams to automatically place a copy to the sent mail folder, which is not standard behaviour though. A short Google search brought me to this: https://stackoverflow.com/questions/47472170/mail-sent-with-php-mail-are-not-shown-in-my-mails-sent-folder Maybe it is of any help…
