My linux mail server returns an error everytime I send a mail to our server as mymail@domain, however it is successful when I run it using firstname.lastname@example.org.
I already made our dns to have an entry::
domain. IN MX 10 mailserver
And I thought that this would solve it, but still an error mail returns to me saying
----- The following addresses have delivery notifications -----
<email@example.com> (unrecoverable error)
----- Transcript of session follows -----
554 MX list for addu.ph. points back to mailsrv.addu.ph
554 <firstname.lastname@example.org>... Local configuration error
What did I do wrong? Any suggestion?
