DMARC and CommuniGate Pro Mailing Lists
Question
Why is delivery of mail generated by CommuniGate Pro mailing lists to Yahoo and Gmail users is failing with the following message in the CGP logs?
421 4.7.0 [XXXX] Message from (XXX.XXX.XXX.XXX) temporarily deferred - XX.XX.XX. Please refer to http://postmaster.yahoo.com/errors/postmaster-21.html
Answer
To be compatible with DMARC, please enable the 'Hide From Addresses' setting for the CGP mailing list(s) in question.

Preserving the "FROM:" address is not compatible with DMARC.
