[Mailman-Users] new user ... some emails sent, some not

[Sherry Lumpkins]

I'm a new mailman list administrator.  My mail list implementation is through my web host.  I actually have several mail lists across several web sites, all the same web host, all mailman mail lists.

My problem is that the mail lists seem to be sending email to some of the list members but not all of the list members.  My member list sizes range from about 30 to over 2,000.

I've searched FAQ but can't find my specific problem (reaching some but not most).

I have tried to follow the instructions from the "No messages sent" FAQ but it appears that my host hides those file paths.

Please advise...thanks for any support you can offer...sorry if this is a redundant question.
