Re: [exim] Lots of incomplete transactions

I added the +log to log_selector and had the guy send another email to
that address...

I appended the +all to the beginning of the other variables for
log_selector - will that not output more detailed information if I leave
the other settings enabled?

Any ideas what might be going wrong? As always, thanks in advance! :)
