This is with added debug info.
message numbers are external (1..) not internal (0..).

Same thing:

dovecot: Jun 02 12:39:45 Info: POP3(jenslt): RETR: fetch 1944
dovecot: Jun 02 12:39:45 Info: POP3(jenslt): DELE msg 1944 deleted

Could it be possible for dovecot to somehow repeatably process the same 
commands over again ?
But this seems strange as it needs to repeat two commands not simply the 
last command.

Something is really wierd. Again: it works with other pop servers.

Maybe Timo has a bright idea.. debug patch? :-)
