Hi,
We are switching to SMTP with port 587 (TLS) and we encountered some issues.
Everything works with port 25 (no SSL/TLS).
I put the "debug SMTP" and I have this log:
2024-03-13 15:03:04 SERVER -> CLIENT: 220 mail.server.com ESMTP
2024-03-13 15:03:04 CLIENT -> SERVER: EHLO

2024-03-13 15:03:04 CLIENT -> SERVER: STARTTLS
2024-03-13 15:03:04 SERVER -> CLIENT: 220 Go ahead with TLS
2024-03-13 15:03:04 CLIENT -> SERVER: QUIT
2024-03-13 15:03:04 SERVER -> CLIENT: 454 TLS not available due to a temporary reason
2024-03-13 15:03:04 SMTP ERROR: QUIT command failed: 454 TLS not available due to a temporary reason
SMTP connection failed.
Do you know if I can have more details in the logs?
Did I miss something.
