[Mailman-Users] does mailman ever automatically delete an expired email address?

[Jane Frizzell]

Hello
Does mailman ever delete members from lists automatically for any 
reason? One of the owners of one of our lists (only 1 list seems to have 
been affected) recently reported that he had lost 100 users from his 
list. They were removed, not just marked as nomail. A primary look at 
some of the names lost. show that the addresses were no longer valid 
email addresses. The addresses would have expired about 6-8 months ago. 
The message he got as he was the owner, one message per address was:

Thank you.  Jane
