Should I Use Two SSL Certificates on The Same Server?
I have one physical dedicated server. The name of the server is 'mail.iamghost.tld' which is obviously my Postfix mail server for my users. Now I generated SSL self signed certificates with 'OpenSSL' which is for 'mail.iamghost.tld'. I also have Apache installed on the same server to access my webmail application. I created a pointer record for 'www.iamghost.tld' to point to the same static I.P. as 'mail.iamghost.tld'. So my question is if I also want to encrypt site login's for www.iamghost.tld/webmail, do I need to generate a unique SSL certificate for 'www.iamghost.tld' or can I use my existing SSL certificates that are assigned to 'mail.iamghost.tld'? It's the same server but when people browse to my 'www.iamghost.tld/webmail' site, I don't want there to be an issue with the certificates saying it's for 'mail.iamghost.tld' when they're really communicating with 'www.iamghost.tld'.
Thoughts and or suggestions?

Re: Should I Use Two SSL Certificates on The Same Server?
If it's self-signed, just regenerate the certificate/CSR for *.iamghost.tld (ie, wildcard) then the same cert will work for everything in that domain. It's what I do for the archserver.org sites -- saves a lot of overhead in management of certificates.

I didn't know I could do that. Is that not frowned upon when people look at your certificates or is that normal / acceptable practice?

Wildcard's aren't common (they're very expensive from trusted CA's) but they're perfectly valid and normal.

Thank you. As long as it's 'valid' & 'normal' then since it's a self signed certificate with no CA, I think this falls right with in budget.
