Here is the output:

This appears to be a C library/OS issue that has nothing to do with
Mailman. getgrgid(gid) should return a struct group for the group
whose ID is gid. This structure should contain the information which
is a representation of the fields in the /etc/groups record for that
gid. If gid is valid, the return from getgrgid(gid) should not be null.

Mailman only cares about getgrgid()->gr_name.

You got it Mark!
I didn't think to check those paths, and in fact they were wrong.
The error in the log was misleading me, nothing to do with virtual users 
and mysql...
I should have started with the simplest things...
Thanks a lot, I hope this thread can be useful to CentOS users.

Can I use /usr/sbin/postmap myself to update virtual-mailman.db?

Hi Mark,

I have moved my domains to a new server and have copied many mailing 
lists from the old server to the new one instead of creating them on the 
new server one by one.

Now I see that the virtual-mailman file isn't updated for these simply 
copied mailing lists, but only for newly created ones. The file warns me 
to edit it myself, but rather have it auto-updated from the 
virtual-mailman.db file.

If I have understood the process correctly, every time when I create a 
new mailing list, Mailman will add the relevant data to the 
virtual-mailman.db and run /usr/sbin/postmap to have the virtual-mailman 
file updated for Postfix.

Can I do this myself on the Server console? I would really like to avoid 
having to create all these mailing lists again ...

And - yes, they are all properly shown by list_lists and can be used in 
either way, but still not via the email interface.

Any help is appreciated, as always.

Actually, that's not what the warning means. See below.

That's backwards. Mailman adds the relevant data to the virtual-mailman
file and then runs /usr/sbin/postmap to update the virtual-mailman.db
file from virtual-mailman. When you put something like
hash:/path/to/data/virtual-mailman in your Postfix config, that tells
Postfix to consult the corresponding /path/to/data/virtual-mailman.db
database and to generate warnings in its log if the
/path/to/data/virtual-mailman.db is not at least as new as
/path/to/data/virtual-mailman

>Can I do this myself on the Server console? I would really like to avoid 
>having to create all these mailing lists again ...

What you want to run is Mailman's bin/genaliases which will completely
rebuild data/aliases and data/virtual-mailman based on the lists in
the installation including those you added by copying and run the
relevant postalias and postmap commands to update the .db files.

You are probably right. It may be an issue in C library/OS. I will try 
and discuss this in freeBSD lists.

Now here is something that spoiled my sleep: I wrote a small test 
program to call getgrgid(), and it prints getgrgid()->gr_name = www. 
When I added a print statement inside common.c, I get

Two questions ref virtual hosts and mailman

Question 1:
=========

Current situation:
------------------------

I have now pretty much a working solution for this situation (postfix
and mailman installed with Ubuntu packages on 64-bit 10.04 LTS (Lucid
Lynx) :

  1 server
  1 "real" domain: realdomain.com
  2 virtual domains: virtual-1.org
                            virtual-2.org

All are accessed successfully through SSL/TLS (https).

Desired situation:
------------------------

I can get new lists at the virtual domains okay, but here's what I
would like to do: change the mailing list virtual domains to:

  2 virtual domains: lists.virtual-1.org # this is my default domain for mailman
                            lists.virtual-2.org

BUT present the lists to the users as, say, info <at> virtual-1.org

I had some mixed success early on, but other problems intervened.  Now
that the other problems have been solved, I want to blow everything
