Error "TLS encryption required" Print

  • encryption, mail server, transaction log
  • 0

ListManager does not support connectivity with mail servers which require encryption.

As such, there may be instances where mail cannot be delivered to some recipients because the receiving mail server requires an encrypted connection to receive mail.

In these cases, the following error will appear in the transaction log for the member in question:

--> MAIL FROM: bounce-80484-3494097@newswires.ultimatesoftware.com
<-- 450 4.7.0 TLS encryption required
