Group Message Bouncing Back


  • Hello - I am attempting to send an email to a relatively large number of people (about 50). I am getting a large number of the emails back with the following message (email address is fictitious, I get these for a large numer of domains) ---> The following message to <''> was undeliverable. The reason for the problem: 5.1.2 - Bad destination host "DNS Hard Error looking up' (MX):  NXDomain"

    I can successfully send emails to one destination at a time.

    Can someone help?

    Thank you.

  • Could you double check these of your mail profile:

    1. the Seconds Until Server Connection Timeout

    2. the Connection settings like Proxy, Proxy authentication settings...

    3. the Security settings


    Also, could you tell which tech are you using for mail: sql agent? sql mail? or Store Procedures for mail?
