Greetings I need some user opinions on obtaining certificates. Free or purchase ?
I have a bank of relays and imap servers running in my intranet. We have been using self signed certs for ever, but I am thinking that a Free " comodo " style cert may work in this case. But I know absolutely nothing about these in use with email, and I am really confused about the different certificate types. what i should use, and where to get them. good bad indifferent , is there a better way ? systems im looking at primary mx primary dns relays (1,2,3) imap/pop (1,2,3,4,) webmail/apache my primary concern is the smtp relays I have setup for external authentication. any advise would be helpful -j
