It may be worth noting that the open source Zimbra integrated messaging suite uses Postfix as its MTA component. Some noteworthy Postfix using sites in the USA: 1. Stanford University's 4 MX hosts run Postfix http://www.stanford.edu One of the leading research universities in US Cisco Systems powers the internet and was born at Stanford: http://www.stanford.edu/group/wellspring/cisco_spotlight.html Current enrollment 19,535 Graduate students 12,595 mx2.stanford.edu. 1800 IN A 171.67.219.72 mx3.stanford.edu. 1800 IN A 171.67.219.73 mx4.stanford.edu. 1800 IN A 171.67.219.74 mx1.stanford.edu. 1800 IN A 171.67.219.71 2. NASA's 6 MX hosts run Postfix http://www.nasa.gov ndmsnpf02.ndc.nasa.gov. 600 IN A 198.117.0.122 ndjsnpf03.ndc.nasa.gov. 600 IN A 198.117.1.123 ndjsnpf01.ndc.nasa.gov. 600 IN A 198.117.1.121 ndmsnpf03.ndc.nasa.gov. 600 IN A 198.117.0.123 ndmsnpf01.ndc.nasa.gov. 600 IN A 198.117.0.121 ndjsnpf02.ndc.nasa.gov. 600 IN A 198.117.1.122 I don't have time currently to research/confirm others, but there are many high profile and medium to high volume mail sites in the US running Postfix both at the edge and internally. Though the fact that AOL alone, which handles millions of emails per day, is using Postfix should provide ample backing to your proposal to use Postfix. These above are simply icing on the cake. -- Stan
