I'm hoping someone on this list will have an idea as to why i'm getting
this problem. It happened shortly after we upgraded the memory on the
server as well as daylight saving time changes. Suddenly it disappeared,
and then reappeared last night.
When I telnet to the host on port 25, for around 1 min 20 secs, nothing
happens, then it pops up the 220 acknowledgement.
I've tried disabling all RBL and DNS checks as well as making the ident
timeout 0s.. doesn't help.
Here's what debugging shows (with RBL re-enabled):

I've seen one reference to something similar in the archives but it
doesn't provide any solutions..
