Individual SSL-Certs for IMAPS/SMTPS

[Dawn]

Hi,

I wanted to ask here if its possible to set up SSL cert (bought or self signed) to have an individual SSL certificate for every domain? I tried a lot of things but I didn't found a solution... I think its very "unnice" to have a shared cert for all domains.

I'm using Plesk 8.1 with Debian 3.1.

You can only set up one cert for qmail (SMTPS) and one for courier-imap (POP3S/IMAPS). Remember that an SSL certificate requires a unique IP address, so you'll need an exclusive IP address for every domain you want to use HTTPS on. This is not a Plesk limitation, SSL certs just need a unique IP address.

Thanks for your answer

That's not the problem, I know that every domain needs its own IP when I want to use a own SSL-cert of it.

But when I have an IP for every domain which should have its own cert, how can I set up the cert for SMTPS/IMAPS for this domain?

I don't know if this is possible. You'd need different instances of qmail and courier-imap listening on all those different IP addresses...

Hmmm sounds very compilcated. But what would you suppose for a professional solution? It sounds like its impossible to offer trusted access to SMPTS/IMAPS... Or am I wrong?

Yes, that sounds complicated. Just create a certificate for your company and use that. Your clients will have to trust your company then.

Ok I'll do that. What a shame that there is no better solution for that problem.. (like https) But thanks a lot for your help!

Well, the https solution is actually the same, but Apache has pretty good virtual hosts support and I don't believe qmail and courier-imap have similar support.
