What is the best way to implement certificate in my case?
I have to implement SSL for IMAP, because many ISPs blocks port 25 and I have problem with roaming users.
I would like to ask first to prevent issues later.
My server name: ns0.test.com
I have A records mail, ftp, etc. which points to the same ip.
I would like to use mail.test.com for client email program configuration (Thunderbird). I have been using this configuration since I started with ISPConfig.
What would be the best way to implement certificate? Additional IPs are no problem.
On what domain I should create certificate. I would like to use free certificate from startcom.org.
I don't currently use certificate.
Thanks for help.
