DKIM Problem

Post by petesky » 2023-01-20 15:20

Hi !

Whenever i send a mail trough Thunderbird, DKIM passes but when using a PHP SMTP Mailer trough HM (very simple plaintext mail) DKIM will be signed by HM but DKIM test shows "bad signature". I compared the two mails (TB source and PHP source) and i cannot find any differences so i assume there is something wrong with NL/BR or WHITE SPACES or whatever ?

Can someoneone give me an advise how to debug this ? Is this a problem in SMTP class ?
HMS 5.6.9 on Windows 2003 x86 :-)
Btw. this server is great & stable and i hope HMS still works in future.
