Issue/Introduction
While sending email via Release Automation email action
This email has been sent from an invalid sender domain and will be blocked on 11/9 if not corrected. Valid Domains: @domain1.com ,@domain2.com,@domain3.com, @domain4.com
Cause
1: The error reflect a failing callback verification or Sender Address Verification. In this SMTP is trying to verify the "Mail From" domain and unable to find "customdomain.com". This is feature, used as an anti-spam measure.
2: In above process the receiving mail server verifies the sender address, i.e. the domain name (part after the @ character), and the local part (part before the @ character)
There is nothing wrong with Release Automation action rather an error at SMTP server side. At this point we can provide below suggestions. If it was working earlier and started to fail recently, there may be some change made in SMTP Server (Receiver end) which is now causing the callback verification failure.
Environment
Release : 6.4, 6.5, 6.6, 6.7 or higher
Component : CA RELEASE AUTOMATION RELEASE OPERATIONS CENTER
Resolution
Suggestions:
1: Try to add domain "customdomain.com" as an additional domain to SMTP server(receiver end), so that it is a valid domain and doesn't get failure at callback verification as it will be able to find a valid MX records for the domain.
2: Try to change "Mail From" address to something like [email protected] with valid domains from below list @domain1.com ,@domain2.com,@domain3.com, @domain4.com
