Hello, I'm making a survey about internet mail (focus on number of large sites): which kind of servers used, amount of accounts hosted, etc. I don't know how to get this info, the only thing I can is look into the full header of the mails. I don't know that info either critical or not. Anybody here can point me where and how to find some pieces of info for this ? If you are administrators of that sites, can you give me some advices ? I'm working for an ISP which would like to switch from Netscape Messaging to qmail. Thanks in advance.
