With 'Pop Before SMTP' Enabled on the MMP, Why do some SMTP Clients Not Need to Authenticate?
Last updated on JUNE 20, 2017
Applies to:Oracle Communications Messaging Server - Version 6.3 and later
Information in this document applies to any platform.
Checked for relevance on 01-06-2014.
In the Messaging Administration Guide, on 'Enabling POP Before SMTP', in the section 'To Install the SMTP Proxy' the following is written :
4.Make sure the IP address that the MMP uses to connect to the SMTP server is not treated as “internal” by the INTERNAL_IP mapping table.
See To Add SMTP Relaying for information about the INTERNAL_IP mapping table.
We have made sure this is configured correctly but nevertheless we see a certain smtp client does not need the 'POP Before SMTP' process to be able to send mail.
We've checked and it seems the client IP address is inside the INTERNAL_IP range inside the mappings file..
Is this expected ?
