Weird SSL horde wrong certificate error on one domain 'webmail'

[David Cottle]

I got a weird problem I can't track this down.

I got one domain that if I go

https://www.domain.com

I get the correct certificate.

I try https://domain.com

Its also correct.

But https://webmail.domain.com pulls up the wrong certificate the plesk default.

The DNS is set correctly all resolve the same IP, so it's some weird vhosts thing with webmail.

Every other domain is okay, just one domain doing this.

What is wrong and where?

Thanks!
