Exim4 + Sophos XG Relay

Hey! Good morning everyone! ;) I'm trying to configure a relay together with another provider I have. (set up as relay) I have an email called 'noreply@sub.domain.com' configured as a relay and I would like to envelop messages like 'contact@domain.com'... If I forward directly from the account, everything goes perfectly, but if I add the 'FROM ', I get the erros: A=dovecot_login:noreply@sub.domain.com rejected after DATA: Your FROM address ( contact@domain.com, CONTACT ) must match your authenticated email user ( noreply@sub.domain.com ). Spoofing not allowed!
Section: AUTH: sophos_login: driver = plaintext public_name = LOGIN client_send = : noreply@sub.domain.com : pass Section: PREROUTERS: send_via_sophos: driver = manualroute domains = ! +local_domains senders = *@sub.domain.com transport = sophos_smtp route_list = "* imap.sophos.com::25 byname" host_find_failed = defer no_more Section: TRANSPORTSTART: sophos_smtp: driver = smtp hosts = imap.sophos.com hosts_require_auth = mail.domain.com #hosts_require_tls = mail.domain.com I would like some help to resolve this issue and allow wrapping of sub.domain.com in domain.com to be allowed.
