Now, suddenly, outlook stopped rejecting username and password (i think it's somehow connected with the dns server refreshing time).
But now i get this error when i try to send an email via outlook:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'firstname.lastname@example.org'. Subject 'test', Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: SMTP, Server Response: '554 <email@example.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
is some working mail adress.
and also, if I try to send a mail from somewhere else to my firstname.lastname@example.org
, i get this err:
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 550 <email@example.com>: Recipient address rejected: User unknown in local recipient table
