Would it be possible to save sent email to the sent folder without having to re upload the email to the sent folder?
I use Thunderbird but I guess this would be the same for every IMAP client. When I send an email it sends it to the recipient via SMTP then re-uploads it to the sent folder via IMAP. If the email has attachments this can take a long time. With my internet connection, a very long time…
With Roundcube this is all handled on the server so is quick. I guess the solution would be to configure the SMTP service to save all messages to the sent folder?
