I use EMailMessage and SMTPSecureSocket to send confirmations to clients.
Works ok, no complaints.
But lately I get more and more bounce emails regarding RFC 5322 violations.
In this case it’s a xojo 2024r4.2 webserver running on ubuntu and sending emails via a hoster.
Cause is the line with Date: like:
Date: Mon, 24 Mar 2025 11:37:47 0000
It should be (at least) regarding RFC 5322 chapter 3.3
Date: Mon, 24 Mar 2025 11:37:47 +0000
or
Date: Mon, 24 Mar 2025 11:37:47 -0000
Better of course would be a date with the correct timezone like:
Date: Mon, 24 Mar 2025 11:37:47 +0200 (CET)
Is smtpsecuresocket responsible for this line (then it’s maybe a bug), or where gets this line added?
Can I somehow modify the behavior?
