Guys, sorry for my bad Inglês, is not my native language
I have today an e-mail server Postfix That runs and use a commercial certificate of Thawte. This certificate is used for connections via Webmail, IMAP and POP. and works very well.
I am migrating this server e-mail to the Zimbra Open Source and 7 am HAVING some doubts about the SSL certificates.
Can I reuse my old certificates Which Were used in the old server? If yes, is there any process I have to take?
If I Can not take my old certificate, then I must generate a new one. When I generate the new certificate in Thawte, I generate the certificate for the domain mail.xxxxxx.com
Here it is my greatest doubts. When I ride my server, the name of my server has to Be Exactly equal to the domain name in the register in Thawte? or Can I use any name for the server? and then generate a certificate in the Thawte for mail.xxxx.com domain?
Thank you for everyone's help.
