I would like to publish non-self-signed SSL certificates for some linux mail servers, which operate SSL and/or TLS mail services. (If relevant, these are dovecot+sendmail servers.)
I need to cover the usual {mail,smtp,smtp2,imap,pop3,...}@dom.ain server names, so naturally I thought of purchasing a wildcard *@dom.ain. (UC seeming unnecessary, they all stem from the same dom.ain name)
I have done that already for websites with few or no issues, but I would like to know if mail usage is any different - from a client perspective - since the main objective is avoiding issues with client software complaining about self-.signed certs.
Cheers, alf
