As of 3 September 2007, the main lists had the following number of members (some of these could be set to nomail, but its a reasonable approximation as some are also feeding mailing list expanders).

• exim-announce - 1737 members
• exim-users - 1957 members
• exim-dev - 210 members

The total number of unique members across these 3 lists are 3802, 240 of these are currently set nomail [these figures are a month old - we have just dropped 500 undeliverable users from the announce list]
