Any ideas what's happening here ?

The increasing delays remind me of the delays for failed logins.
Is there some sort of authentication, or similar pam or SMB access,
to check the existence of each recipient ?


i made a test mail with 3000 recipients in CC.

Exim is increasing it's CPU Usage the more recipients are used until 100% CPU 
Core usage is reached:


     PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM TIME+ COMMAND
1378404 root      20   0   66084  55300  10632 R  98,7   1,1 8:59.99 
/usr/sbin/exim -Mc 1lKd2y-005m5p-3V


I have a static linear timeframe from one recipient to another appearing in the 
log file, once the actual delivery from thunderbird ended.
strace says, it's due to my SQL select i use. it would go faster if the SQL 
result would be cached, instead of repeating itself.


Could you show us the ACL line?
