As discussed on the list, yes, IMP-cvs does prevent multiple
submissions, and multiple posts are a browser/proxy fault.
Yes, my misstake.

Just for the record: The driver for token was set to none so this did 
not work. After changing $conf['token']['driver'] in conf.php I got 
rid of duplicate messages.

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@stockholmpride.org

qmail: 1146081930.280561 starting delivery 5421: msg 6734278 to  local 
2-i.n@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

/horde/imp/compose.php?uniq=18mqhdmzlmps HTTP/1.1" 200 4995

"http://webmail.stockholmpride.org/horde/imp/compose.php?

actionID=reply&index=1005&identity=0&array_index=85&thismailbox=INBOX&uniq=1146081544436" "Mozilla/4.0 (compatible; MSIE 6.0; Windows

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

"http://webmail.stockholmpride.org/horde/imp/compose.php?ac

tionID=reply&index=1005&identity=0&array_index=85&thismailbox=INBOX&uniq=1146081544436" "Mozilla/4.0 (compatible; MSIE 6.0; Windows

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.
