I’ve been running MIAB for a long time, but in testing a new mail sender for work (sender=MailGun), messages to my box are being rejected:
“SMTPUTF8 is required, but was not offered by host”
Of course I did search the forum first and found a couple of closed posts, but have not found a solution to this.
Has anyone encountered and solved this?
I’m on Version 0.51at present
