[Mailman-Users] mailman list questions about password and bounces-back for invalid emails

Hi,

I have 2 simple questions about mailman mail lists:

1). I can see there is an option to receive monthly reminder of
password, and the password is sent in plain text. Is the password in
plain text visible to the mail list owner / administrator? Or mailman
stores a secure hash of the password like sha-256 or ripemd-160? If
the password is stored in hash format, how come I can receive it
monthly in plain text?


2). If an email address works for some time but becomes suddenly
invalid (e.g. server down, domain cancelled, etc.) and when messages
are being sent to that address they bounce back with permanent
failure, will mailman remove these email addresses automatically? If
yes, after how many attempts of sending? What if the email address
server is just down for a day or something.

Thank you!
