Re: New warning: PRMT not found

[Paul Menzel]

Dear Rafael, dear Len,


Intel’s MTA rejects Erik’s address:

    <erik.kaneda@xxxxxxxxx>: host mga17.intel.com[192.55.52.151] said: 
550 #5.1.0
        Address rejected. (in reply to RCPT TO command)

So, I assume Erik left Intel.

The new warning shows up on a lot of systems, with no indication what to 
do about it or why Linux actually warns about it.

Should the message be removed entirely? Or is there another indicator 
for systems where absent PRMT causes problems, so should be warned about?


Kind regards,

Paul
