I've stopped receiving mail from fedora users

[Sherman Grunewagon]

For the past few days I've stopped receiving e-mail from the fedora list.

I' checked my fedora membership mailing list config and found this:

   We have received some recent bounces from your address.  Your current bounce score is 3.0 out of a maximum of 5.0.
   Please double check that your subscribed address is correct and that there are no problems with delivery to this address.
   Your bounce score will be automatically reset if the problems are corrected soon.

I can't see anything out of order on my ymail.com account profile. (I've changed nothing.) 

There are no filters and no blocking set. I really don't know what to do at this point. Who should I contact and what else should I check?


Any help will be appreciated!  (I'll monitor <http://lists.fedoraproject.org/pipermail/users/>)
