<P><FONT SIZE=2>You just have to arrange a so called "drop-box" ;)</FONT>
</P>
<P><FONT SIZE=2>A possible solution could be:</FONT>
</P>
<P><FONT SIZE=2>on your DMZ-mailserver you have to add one account for each domain.</FONT>
<BR><FONT SIZE=2>In your virtusertable just add:</FONT>
</P>
<P><FONT SIZE=2>@yourdomain domainaccount</FONT>
</P>
<BR>
<P><FONT SIZE=2>On your LAN-mailserver you shall use fetchmail (you may already use</FONT>
<BR><FONT SIZE=2>fetchmail now)</FONT>
</P>
<BR>
<P><FONT SIZE=2>in your .fetchmailrc you shall have something like:</FONT>
</P>
<P><FONT SIZE=2>poll DMZ-mailserver with proto pop3 user domainaccount there with</FONT>
<BR><FONT SIZE=2>password "hidden" is * here</FONT>
</P>
<BR>
<P><FONT SIZE=2>That should work ;)</FONT>
</P>
<P><FONT SIZE=2>> > One minor annoyance is that if the aliases (as well as every</FONT>
<BR><FONT SIZE=2>> > other valid</FONT>
<BR><FONT SIZE=2>> > email address) are not defined on the proxy then the mail is</FONT>
<BR><FONT SIZE=2>> > rejected. So,</FONT>
<BR><FONT SIZE=2>> > all the email IDs and aliases have to be on the proxy. But</FONT>
<BR><FONT SIZE=2>> > if any ID or</FONT>
<BR><FONT SIZE=2>> > alias is not ALSO defined on the mail server then mail sent</FONT>
<BR><FONT SIZE=2>> > from the LAN to</FONT>
<BR><FONT SIZE=2>> > that ID tends to bounce since the mail server (correctly)</FONT>
<BR><FONT SIZE=2>> > thinks the mail is</FONT>
<BR><FONT SIZE=2>> > destined to itself but does not find the ID or alias. So,</FONT>
<BR><FONT SIZE=2>> > user IDs and</FONT>
<BR><FONT SIZE=2>> > aliases need to be defined twice, identically, in both the</FONT>
<BR><FONT SIZE=2>> > server and alias.</FONT>
<BR><FONT SIZE=2>></FONT>
<BR><FONT SIZE=2>> Maybe I'm missing something here, but I can't see why you need to</FONT>
<BR><FONT SIZE=2>duplicate your aliases - unless your mailscanner box isn't set up to</FONT>
<BR><FONT SIZE=2>relay for your domain. I use mailscanner in front of an exchange box</FONT>
<BR><FONT SIZE=2>and my mailscanner box doesn't know any of my users names.</FONT>
