Error sending email via google's smtp server

Hi folks,

I have a bit unusual case because I'm running The Bat via Wine on Ubuntu 21.04.

For some reason newer version of The Bat no longer can send email via Google's SMTP server.

After a bit of experimenting I noticed that error occurs only when I have small jpg file attached to the email. Here is how log looks like

Code

It works if I use IMAP. What could be the issue and how to fix it ?
