Since you are using a .de e-mail address i suppose that you speak german :-) If so, take a look at pofo.de.

Subject: [vchkpw] SMTP after POP
Hi,
I have a question is smtp after POP feature supported in the newest
Courier Imap?
I have installed courier-imap-4.0.2 and courier-authlib-0.55 everythink
is OK but
the SMTP after POP feature is not working.
Is there any know issue or I am doing sometihing wrong?
I was looking into .c code courier-authlib-0.55 file: authvchkpw.c
if ( (vpw->pw_flags & NO_RELAY)==0 && ((strcmp("pop3",
service)==0) || (strcmp("imap", service)==0)) ) {
/* Michael Bowe 13th August 2003
*
* There is a problem here because open_smtp_relay needs
* to get the user's ip from getenv("TCPREMOTEIP").
* If we run --with-authvchkpw --without-authdaemon,
* then this var is available.
* But if we run --with-authvchkpw --with-authdaemon,
* then TCPREMOTEIP is null
*
* If TCPREMOTEIP isnt available, then open_smtp_relay()

IMAP-before-SMTP is possible when using Courier-IMAP v3.x. However it only works when configured "--with-authvchkpw --without-authdaemon". When running --without-authdaemon, Courier-IMAP's authvchkpw code is able to make use of vpopmail's roaming user functions to allow IMAP-before-SMTP functionality. IMAP-before-SMTP is not possible when Courier-IMAP has been complied --with-authdaemon, because in this mode the user's IP address is not made available to the authvchkpw code (via the TCPREMOTEIP env var). Also note that in Courier-IMAP v4.x and later, --without-authdaemon functionality is no longer available thus preventing IMAP-before-SMTP from working. Courier-pop3d uses the same backend code as courier-imap, so courier-pop-before-smtp is also not available in v4.x Michael.

Augh... I mean "IMAP before SMTP", which actually doesn't sound as silly.

Courier IMAP provides neither POP nor SMTP services. It provides IMAP
services. If you are asking for IMAP before POP (sounds kinda silly to
me, but people have asked for it before), then yes, Courier IMAP can do
this.

It is possible that you're using a NAT router/gateway between your home network and your ISP? If so, the NAT address on the WAN side of your router serves both of your home computers.
