Subject: Re: [Exim] SMTP Coversation delay
Hello!

I am also having this problem. I have also tried similar things to
restore this issue. Strangely, nothing has been changed on the system
and I seem to have exactly the same problem since the weekend, possible
daylight savings changing issues???!!

Any assistance to this would be appreciated.

Thanks!

Shane.
