Telnetting To Port 25 Omits Envelope Signature In Newer MTA
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 0N9400NSBQ874100@mydomain.com
But, on the newest MTA using Oracle Communications Messaging Server 184.108.40.206.0 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?
