Why is my QMAIL server having trouble performing recipient verification over SMTP with my Email Security Gateway?

  • Type: Knowledgebase
  • Date changed: 11 months ago
Solution #00000657

Scope:
All Email Security Gateways used in conjunction with a QMAIL server, all firmware versions.

Answer:
By default the QMAIL email server software will not validate recipients during the SMTP transaction. However, there is a patch available so that QMAIL can return a 550 error for invalid recipients during the SMTP transaction.

Information on the patch can be found on the following website:
