A simple message from person A to B and  person B received 9 copies (with
diffrent message-id in the messageheader). It is a stocastic problem, not
easy to reproduce and it only happends when the sender is using IMP as mail
client. 

I use qmail as MTA and if I interpret qmail's maillog correctly  there is
repeated deliveris of the same message with diffrent IDs in the maillog.

qmail: 1146081929.528803 starting delivery 5420: msg 6734278 to  local
2-i.n at stockholmpride.org
qmail: 1146081930.280561 starting delivery 5421: msg 6734278 to  local
2-i.n at stockholmpride.org ... etc

Since I also see corsponding multiple HTTP Post in the access_log I  suspect
that the browser has actually posted the same message several times.

access_log:
212.151.252.253 - - [26/Apr/2006:22:05:28 +0200] "POST

Maybe this is not a common problem but does IMP prevent the action 
"send_message" to be executed for the same value of uniq parameter to
compose.php? If not, adding this check would prevent the same message from
being sent several times.
