In summer of 2001, this was about 5,000 downloads per month. You can see the latest traffic stats here: http://www.apache.org/~vgritsenko/stats/projects/james.html + ---- '''Q:''' How stable is James? On a suitable server does it crash once a week, month, or never? '''A:''' + - * '''(Kenny)''' I've been running my James install for about 5 months and I found it not running only one time. I don't know if it was James or badness on my server that caused it to die, but regardless, it's very stable. + * '''(Kenny)''' I've been running my James install for about 5 months and I found it not running only one time.

My current install is 2.2.0a3, but that just went on line last Thursday. The previous version I used was 2.1.2a2 installed on 2/21/2003 and had no particular problems that I was aware of other than getting slow to respond when a spammer was deliberately trying to crash it. + * '''(Chris)''' In it's latest incarnations, I've not seen James crash once.

''It would be useful if above people would detail how many mailboxes (and messages per day) their setup supports.

Thanks'' @@ -28, +32 @@ '''A:''' Noel has run benchmarks of 600,000 (incoming) messages per day on an outdated 400Mhz Celeron running linux 2.2, and there is excess CPU remaining. He uses "postal", "rabid" and an SMTP sink, which can be found on the JamesRelatedTools page, to simulate a combined SMTP/POP3 environment. '''Update:''' We have scalability test results at JamesByTheNumbers. + ---- '''Q:''' Has anyone had any problem incorporating custom Mailets into the server or experienced any unusual problem with database connections? '''A:''' Yes, it is difficult to add custom mailets. As of James v2.2 this is significantly easier. See CustomMailetPackages. Database connection pooling code is getting reworked and will not survive a database outage. + ---- '''Q:''' Is there a published list of corporate users that anyone knows about? '''A:''' We still start compiling a list here. Please feel free to add your name. In the meantime, the JamesUsers page collects comments from some existing users. + ---- '''Q:''' Would you recommend James (version 2.1.3) as a production, scalable MTA? '''A:''' Absolutely! James has great throughput capability, and we can assure you of its incredible flexibility and extensibility!
