I have a VPS that is currently hosting a website and also serves as a mail server running exim
. I own a SSL certificate for website.com
which also works for www.website.com
.
Since my server's FQDN is server.website.com
I cannot make use of my certificate for emails, so I was wondering if it was a good idea to change my hostname to www.website.com
?
I was pretty confident that it was a good idea... until I found this on WHM:
Hostnames should never begin with “www”
Is this definitely a no no? Would it be better to do a custom hostname configuration for exim?
Is it even reasonable to name a mail server as www.something.com
?
