I have a problem with some clients that use exchange server.
This the scenario...
domain1.it is on iredmail server, but sends email form internal exchange server
domain2.it is on iredmail server and send and revice using iredmail services.
When domain1.it try to send an email to domain2.it, iredmail reject the email;
below is the log
Jun 28 17:33:00 mx postfix/smtpd: NOQUEUE: reject: RCPT from unknown[22.214.171.124]: 553 5.7.1 <firstname.lastname@example.org>: Sender address rejected: not logged in; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<domain1.it>
I think it is because domain1.tld is not logged in the iredmail smtp server.
Is there any way to solve this issue?
Another option is to use the Microsoft Exchange connector for use an external SMTP server, but I can't use iredmail because the connector accept only one account (like email@example.com) so if the sender is firstname.lastname@example.org the email was sent, but if the sender was email@example.com the authentication failed.
I hope it was clear.
