Telnetting To Port 25 Omits Envelope Signature In Newer MTA

(Doc ID 1916055.1)

Last updated on SEPTEMBER 07, 2017

Applies to:

Oracle Communications Messaging Server - Version 7.0.3 and later
Information in this document applies to any platform.


When I test mail routing with a "telnet <MTA host> 25" command on older MTAs using Sun Java(tm) System Messaging Server 7u3-17.01 64bit, I get the following output:

250 2.5.0 Ok, envelope id

But, on the newest MTA using Oracle Communications Messaging Server 64bit, I get:

250 2.5.0 Ok.

Notice that there is no envelope signature.

Why am I seeing a difference in the output from the telnet between the different versions of the MTAs?
