I do not understand what this means. Do you mean that a moderated
member was able to post to the list without the post being held, or do
you mean something else?

2. and 4. sound like a stale lock problem. See

For 3., the filtering of administrivia from the list is very simplistic.

For a message to be detected as administrivia, it must have fewer than
DEFAULT_MAIL_COMMANDS_MAX_LINES (default 25) non-empty body lines
preceding a "-- " signature separator, and then the body must either
consist of a single command word, or there must be within the Subject:
line and the first 5 body lines, a line that looks like an email
command with an appropriate number of arguments.

I.e., a message that has a line

  Unsubscribe me from this list

will not be detected as administrivia because the "Unsubscribe" command
has too many arguments.
