I already have that one (*.the-grue.de) and it's working perfectly :) > and then have your customers use that in > their MUA as the host to send and retrieve mail. But then the hostname for the virtual domains won't match, won't it? Can I use the certificate for *.the-grue.de for *.virtualdomain.de? > This is the simplest of setups, without any hassle long-term.

I think the virtual domains are very practical :) Thanks for your help! -- Markus Grunwald http://www.the-grue.de Männerchor Markt Kirchseeon Registered Linux User 101577 Notenwart und Webmaster http://counter.li.org http://www.maennerchor-kirchseeon.de pgp/gpg key ID 79D7E890 Fragen zur Mail? http://www.the-grue.de/mail_und_co/
