[courier-users] what causes delay in getting the 220 ESMTP greeting?

[Ricardo K. <ri...@am...>]

Hi,

I'm trying to debug why sometimes it takes quite a while to get the 220
greeting on port 25.

I thought maybe it's the filter (I use pureperlfilter) but I only have
that enabled on esmtp and the delay I get is on localhost (telnet
locahost 25)

The server is not very busy. Sometimes it will take many seconds to get
the 220 response even when the server is not busy, sometimes it's
immediate.
