 Wildcard Cert
I don't know if it's an option for you, but you could try using a wildcard cert. I've been testing it myself and have been pretty successful with SMTP/TLS(port 25), https, imap(on perdition), and pop(on perdition) using a test cert from thawte. I haven't gotten smtp over ssl(port 465) working yet, but am working with support on it.
The wildcard cert would allow you to use any DNS name you want. If you need to change it in the future, you don't have to get a new cert. However, it also costs a little extra $$. |
