I am a list admin for other lists hosted here at Notre Dame, and the times I have had problems like Ralph has reported, they are usually because:

* the DNS is reporting a mismatch for the outbound mail server between IP address and hostname
* the subscribers addresses are actually sent out as a different address than the one that the subscriber is subscribed with
* the mail host has been flagged as an open relay for spam and other nastiness, and go gets blacklisted

Ralph, did you folks recently change anything with your mail servers?  Please respond to me off-list and I can put you in touch with the primary listserv admin here at ND.  Thanks!

I haven't seen this problem, but I guess I haven't sent a message to the list recently. We'll see what happens when this goes out.

We've been having a similar problem with other listserv lists (autocat and oclc-cat) since the beginning of March. We just stopped getting mail from these lists but are still subscribed.

Our mail admins have been working on it in conjunction with counterparts from the hosting institutions but no resolution as yet.
