Now I have no idea why the error message following STLS is in German. It
says  "command not supported". When I try this with telnet, it looks
fine:

Well, at least the other matches our source:
     /* possibly disallow USER */
     if (!(kflag || popd_starttls_done ||
           config_getswitch(IMAPOPT_ALLOWPLAINTEXT))) {
         prot_printf(popd_out,
                     "-ERR [AUTH] USER command only available under a
layer\r\n");
         return;
     }

Perchance if you tcpdump you see the client lying and not bothering to
send the STLS at all?

Well, I have meanwhile tried it myself and have found that it definitely *does* work for me. The user told me that a virus scanner is involved. I'm guessing that it's a POP proxy server and that *it* doesn't support the STLS command. The user claims that it doesn't even work without the virus scanner and that it *did* work with our old UW ipop3d server, but at this point I'm not sure I believe him ;-)

Cheers, Sebastian
