Reason: 5.3.0 - Other mail system problem ('542'

[aangster1]

Hello,

I have one Ironport C370 and when I send a message to an address I have this response

bounced by destination server. Reason: 5.3.0 - Other mail system problem ('542', ['5.7.1 Spiked: templates/60cde3022cf2c937.1.0.419.2522.2820.07090306040200..1/10'])

this recipient correctly receives these emails.

By performing tests still to the same destination but with a different address from our area I saw it functioned.

You would need to check directly with the recipient end as to why they are denying your connection.

5.3.0 --->

Mail system status

       X.3.0   Other or undefined mail system status

          The destination system exists and normally accepts mail, but
          something about the system has caused the generation of this
          DSN.

The '542' = Bad Connection

5.7.1 always means there is a permanent failure of "Delivery not authorized, message refused"

5.7.1   Delivery not authorized, message refused

          The sender is not authorized to send to the destination.
          This can be the result of per-host or per-recipient
          filtering.  This memo does not discuss the merits of any
          such filtering, but provides a mechanism to report such.
          This is useful only as a permanent error.

Hope this helps!
