SMTP long response.

[huglester]

Hello everyone.

WHat does it happen, that even telneting to port 25, from some hosts I get reply in 1-2 secs
and from other hosts ~30secs.

Maybe Qmail is doing reverse-dns check or smth? maybe I should 'somehow' disable it?

I can't see such problem in Plesk 9.0

Thank you!
