E-mail from specific domain not delivered to one of the cc: recipients on Exchange 2010
- by BobC
we have a user on Exchange 2010 server who doesn't get email from one specific domain if her address is in cc: field. If she is a main recipient (To:) it goes through. We checked Exchange logs and it looks like our server doesn't even try to deliver it, it simply ignores her email address completely.
We did several tests:
send email with her email address in cc: field from another domain, succeeded
send email with her email address in to: field from another domain, succeeded
send email with her email address in to: field from affected domain, succeeded
turn off all email rules
check via webmail
We also turned off firewall, antispam and antivirus for SMTP rule.
Does anyone have any idea what could be an issue here?
Thanks
