We use EXIM since decades now from small satellite mailer setups to very large ISP setups after migrated from sendmail and postfix as they brought our hardware down in performance with heavy mail loads. EXIM is very (!) efficient - especially when build from sources the "official" way (what is provided by pkgsrc by build options). This means you just compile fucntionality / code into the binary what you really need. The security footprint is very good. The config is very flexible but of consistent syntax (developed my a mathematican - Phillip Hazel) - for me much more transparent then on postfix. There are many of good examples and howtos out there which provide single config files you could easily adapt and use. But you can split config files too if you prefer that. i can hardly recommend it. just my .02$ good luck, niels. -- Niels Dettenbach Syndicat IT & Internet https://www.syndicat.com
