Postfix/pop-before-smtp virtual domain relay problem on FBSD

[Chris]

Hello,

I am having a problem  using my FreeBSD/Postfix mail server to accept 
relays from my virtual domain clients.  I use pop-before-smtp on this 
server and the users for these virtual domains are able to pop their 
mail but not relay through the server.  Here are some vital settings 
from my main.cf

virtual_maps = hash:/usr/local/etc/postfix/virtual

relay_domains = $mydestination, $virtual_maps

smtpd_recipient_restrictions = permit_mynetworks, check_client_access 
hash:/etc/postfix/pop-before-smtp,check_relay_domains


These virtual domains are postfix virtual domains.  Below what I have 
the virtual file setup as:

#
mydomain.com anything
cstrzelc at mydomain.com cstrzelc


In my pop-before-smtp-config.pl I have the following specified:

$file_tail('name') = '/var/log/messages';

These are the recommended settings per the pop-before-smtp website.  I 
can realy when I am sending from the cstrzelc at mail.server.com to another 
address.  I can not when I try to send from cstrzelc at mydomain.com to 
another address.  I believe these are all the settings I need.

Thank you for you help
