Thanks for the info, so far did you face any problem
due to this work arround ??? like the person trying to
send the mail and he has to wait till your cron job
has to execute???
In my system, My cron job needed. for example, cron job off -> my system isn't realized POP before SMTP cron job on -> my system is realized POP before SMTP
because In my system, tcp.smtp.cdb automatically isn't update.
