@ilpianista I have my own dovecot + series of fetchmail scripts to aggregate mail from different external email sites. I didn't configure SMTP because gmail was throwing everything I'm sending to spam folder. Maybe because it was hosted on OVH, which is probably a popular choice for spammers, I'm not sure.
Ouch, I didn't consider the "gmail trustness" of supremevps at all :-/
Thank you for the feedback!
