It doesn't matter.

Have a look on this discussion, it could help you:

I just found this:
the TLS feature "Server Name Indication" will solve all the described 
issues with certificate requests.
How far is that draft in the process of standardization at IETF and is 
there any XMPP server supporting this? OpenSSL version 0.9.8j and higher 
is supporting this and it was released on 7-th of January 2009...
