Is is possible to disable port 25 authentication in SM?
Question asked by Ben Conner - September 27, 2017 at 8:39 AM

Hi,
I recently found that some of my users are still using port 2 rather than 587 to authenticate.  Is it possible to disable authentication on port 25?
 
Thanks!

Hi Linda,

That's close, but the member there wanted to block port 25. I can't do that as I send/receive mail from other servers. What I want to to is disable just authenticated access on port 25, leaving it open for non-authenticated traffic coming from other servers.

Thanks!

Understood. I'm not sure if this is possible. I'm hoping that SM support will chime in here and let us know for sure.

If the client authenticates using port 25 successfully, what is wrong with that? Is there a benefit to having the clients only use port 587? As long as port 25 doesn't allow relaying without authentication then I'm happy. I don't think there are different logs for smtp submissions, is there?
