Mail Queue Manager : what means YY, NN, YN, etc.

[koolos.com]

Hi all,

Ok, I sent a message to a large mailing list via the cpanel mailing list script,mailman (version 2.1.9.cp2).

Everything works fine, but when I log in whm and look at my Mail Queue Manager, I see about 20 messages, with about 200 recipient listed in it.

My question :

When I open one of those message, I see the recipient list like this :

YY aname(at)somewhere.dot
YY aname(at)somewhere.dot
YY aname(at)somewhere.dot
YY aname(at)somewhere.dot
YY aname(at)somewhere.dot
YY aname(at)somewhere.dot
NN aname(at)somewhere.dot
YY aname(at)somewhere.dot
NN aname(at)somewhere.dot
NN aname(at)somewhere.dot
YN aname(at)somewhere.dot

What is the meaning of the two digits codes : YY, NN, YN, and even NY ?

Thanks!

S.

This actually has nothing to do with WHM, rather the MTA on the server. If you are using exim you might want to check out their documentation:

The short answer is that the list of addresses you see is the list of
addresses *not* to be delivered to (this may mean they have already been
delivered)
