I need to know the names of some medium to large ISPs that uses Postfix as their SMTP server. Do you know where I can find that information?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
At least one of the big player in computer market is also using Postfix: goog@web:~# telnet smtp.hp.com 25 Trying 15.193.32.72... Connected to smtp.hp.com. Escape character is '^]'. 220 g6t0181.atlanta.hp.com ESMTP Postfix EHLO kwsoft.de 250-g6t0181.atlanta.hp.com 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN help 502 5.5.2 Error: command not recognized quit 221 2.0.0 Bye Connection closed by foreign host. goog@web:~#It should be obvious by now that many organisations around the world which value e-mail are using Postfix.
