yeah...its definately when this account is receiving emails. i temprorarily
removed it from mysql (im using virtual accounts) and it seemed to behave
since all the emails bounced back.

NB: i use this account for receiving all the reports from the servers, any
cron jobs that have any out put email to this account.

Anything in the exim logs when this happens?


when this happens, i have more than 20 deliveries for this account in the
exim logs. and exim shows no errors either in delivering them.


Does systems at one2net.co.ug account have any funky forwarding, procmail or
> spam filtering? Try


no forwarding or anything funky at all

# exim -bt systems at one2net.co.ug


that works fine

 exim -bt systems at one2net.co.ug
systems at one2net.co.ug
  router = virtual_localuser, transport = virtual_localdelivery



to see if it gives you a clue.

ill do this when the problem seems to persist most. from the times i have
noted, this is morning hours and evening hours (about 9am and 7pm).

what puzzles me is that this has been running for a while now with out any
ptoblems. it all started when one of the disks was failing, which when
replaced all seemed to be going well, but two days after the disk swap it
started again.

thanks


Mike
