Qmail doesn't scale well with large injection rates. Qmail scaling in that sort of manner is completely dependant upon the filesystem. Now this may have changed, but not that long back everything in submission was in one dir, processing in another dir, just like sendmail (by default) does. This caused the queue manager to stuff up something wicked at high injection rates.

I have been a UNIX geek for quite a few years and in that time I have had the pleasure or displeasure of working with many mail packages. The 2 that I had the most exposure to was Sendmail and Qmail. Now barring any flames about sendmail, once I had exposure to Qmail I will never turned back. Qmail was developed with security in mind, it has never had a security bug in the years it has been available, it is scalable, reliable and easy to administrate. Now I will not bore you with every spec or detail about how it runs but even Hotmail.com uses Qmail as it's MTA. This the one of the leading webmail sites in the world with between 80-100million accounts, and still running strong. I would definitely put my vote to Qmail for any organization, any size! - Robert Bridgham-----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com]On Behalf Of Fisher, Shawn Sent: Thursday, September 04, 2003 11:03 AM To: Nanog List (E-mail) Subject: BMITU This is my first post so please be gentle. I would like to get some opinions on the Best Mailserver in the Universe. Is there a more appropriate list for this question? I have looked at Communigate Pro, IMAIL, and others. I am interested in integrated solution that can scale to handle 500k accounts Any experience good / bad would be great. Thanks /SF
