Hello,
I cannot send an email with attachment via a RT ticket. This is the error message in the logs: Aug 23 09:26:42 MAIL-01 postfix/smtp[29806]: 9DD441D5362: to=<[email protected]>, relay=mx.eon.ie[XX.XXX.XXX.XXX]:25, delay=0.91, delays=0.07/0/0.21/0.62, dsn=5.1.0, status=bounced (host mx.eon.ie[XX.XXX.XXX.XXX] said: 550 5.1.0 q9Sg1j02P2zd5X8019SgxU invalid domain (in reply to MAIL FROM command)) The destination mail server recognises the smtp request as coming from invalid domain however I can send mail from my own account without using RT with no issues. The requestors have the correct email address in the ticket. Any ideas how to correct this?
