Error message when trying to send mail via imap

[982c80311320c1b]

When trying to send a mail via imap I get an error message, but the mail gets sent anyways. That made me send emails accidentally multiple times already.

Failed to send message.

The server needs too long to respond.
Try to change the port to 25, 587 or 465.

Using the Postler version packed with Jupiter

Well apparently Postler also messes with the mails content:

1) The recipient's name "Königs" was changed to "K��nigs"

2) Zoho webmail showed this in my sent folder:

-------------------------------------------------------------------------------------------------------------------
Unable to process this message. It does not follow message RFC specifications.
Click 'More Options'->'Show Original' to view the original message received.
