Hey MyBB Community,
i am using MyBB for my small little forum now for about 1 year. Everything works perfectly since then. I was using phpmail with a smtp relay from gmail to send users authentication emails, but now i build my own mailserver with postfix and dovecot (smtp.madgeeks.de / imap.madgeeks.de) and i connected my Phone (GS8+), Outlook, Thunderbird without any problems.
Now i wanted to switch my forum from phpmail to smtp, so user receive emails from "[email protected]" instead of "root - [email protected]". When i register after the settings changed to SMTP i get the error message:
The mail server does not understand the RCPT TO command. Reason: 553 5.7.1 <[privateadminmail]@gmail.com>: Sender address rejected: not owned by user [email protected]
It actually cant be my mailservers fault, because it works on multiple Platforms in different networks. I think my mailserver needs a sender email or something.
Any ideas?
Thank you in advance!
