[Zope] ProxyPass

[Ben Ocean]

Hi;
I've successfully set up my Zope with SiteRoot to serve pages as though 
they were ordinary URLs and utilizing ProxyPass in the httpd.conf file 
(RH62) to direct traffic to the right place, like this:
 >>>
<VirtualHost 216.145.1.127>
ServerAdmin webmaster@allmyjokes.com
ServerName www.allmyjokes.com
ServerAlias allmyjokes.com *.allmyjokes.com
ErrorDocument 401 /errors/401.html
ErrorDocument 403 /errors/403.html
ErrorDocument 404 /errors/404.html
ErrorDocument 500 /errors/500.html
Alias /icons/ /apache/vhosts/icons/
ProxyPass / http://thewebsons.com:8080//allmyjokes/
ProxyPassReverse / http://thewebsons.com:8080//allmyjokes/
ProxyPass /misc_ http://thewebsons.com:8080/allmyjokes/misc_
ProxyPass /p_ http://thewebsons.com:8080/p_
</VirtualHost>
 >>>
All is well *except* when I try to send email to the server. It doesn't 
route it properly. I'm using sendmail. Any ideas?
TIA,
BenO
