    Default What should the mail server hostname be?

    Hello,

    So we already have a mail.domain.com running Exchange which we're hoping to migrate from. What would be best to name the new Zimbra mail server?

    I'm concerned if we go with anything but mail.domain.com, then we encounter mismatch certificate warning when choosing SSL with an email client. Am I correct?

    Thanks,

    In the first instance you will get a mismatch as the server name will be different, but do not fear their are plenty of Wikis for sorting these out including the server rename aswell :-

    As long as the FQDN is the same as when you create the certificate, you can name the mail server whatever you want. If you change the FQDN of the server you will have to install a new certificate bearing the new name.

    Also, you need an MX and A record in your DNS matching the FQDN of the server to prevent possible issues such as rejection by servers that do DNS checking.
