Hi,

Our email domain is sparrowdesk.com (and host is mta1.sparrowdesk.com)

when we send email to your customer jaya.rv@cherrylabsglobal.com  - the email is rejected with below error.

Aug 12 17:46:03 mta1 postfix/smtp[72888]: 8390D1AF16E: to=< jaya.rv@cherrylabsglobal.com>, relay=mx.zohomail.com[165.254.167.50]:25, delay=5, delays=0.17/0/4.1/0.67, dsn=5.4.1, status=bounced (host mx.zohomail.com[165.254.167.50] said: 541 5.4.1 Mail rejected by destination domain (in reply to RCPT TO command))

Please help to close this issue.

Our mail server may send email from different hosts - like mta1.sparrowdesk.com, abc.sparrowdesk.com.  - but our domain remains as sparrowdesk.com

Regards
Shanmu
