Hi Abdur-Rahman,

nice to see, that there is a quick response to security issues.

I have seen, this as an old and well known security hole in Mailman
since 2006:

A move to Mailman 3 seems to solve the problem:
" In Mailman 3, passwords are both stored in hashed form (i.e. /*not*/
clear text) and the monthly reminder feature has been removed. "
If the default password hash is really "salted sha512", I would strongly
recommend to replace it. I'm wondering why they have chosen such an
insecure default. I took a short look at GNU Mailman and I found there
are several password hashing schemes available. Unfortunately there is
no Scrypt, but Bcrypt is available.

HTTPS would be nice, but I think this is not as necessary as avoiding
this password policy. I think it is generally a bad practice to send
passwords anywhere whether hashed/encrypted or not and Mailman 3 does
not do it now.

I hope this helps to fix the problem.
