Hi all-

Got a toughie here.  We're running iMS 2.4d on a pretty nice machine running
nothing but cfserver, iMS and SQL Server 2000.  I'm having a problem with
our bounceback accounts.  I've got an acount set up for each major slice of
our mailing list, and we're using a piece of software from Alias called
Campaign, running on a separate machine to handle our mailings.  Campaign
runs the queries on our Oracle DB to build our mailing lists and mail merge
our personalized newsletters, which are then sent out through another
machine dedicated to that purpose, running the Lyris SMTP server.

Everything's going smoothly with that portion of the process.  Bouncebacks,
however, are coming back into our iMS machine, and being stored in our SQL
Server DB.  Then, on a 2-minute interval, Campaign polls all of our POP
accounts for bounces, and processes them accordingly, updating our Oracle DB
with bounce increments.  We've been having a problem, and saw this with a
previous version (I forget what I was running before 2.4d) of iMS, where all
of our bounces aren't being processed.  Our numbers, and say, AOL's don't
come close to jiving.  So I checked the DB, and sure enough, there are
28,000 emails waiting in account bounce151, which corresponds to our largest
AOL mailing list.  I haven't backed out numbers yet, but the fact is,
bounce151 just isn't connecting to the POP server at all, but every other
account is.  No errors showing it tried to log in and failed.  It just skips
from bounce150 to bounce152.

My CEO recently called me in because he was recieving an error connecting to
the POP server with Outlook 2000, and after checking with everyone in the
office, determined that he's the only person who was having problems, and
there were no configuration changes.  I had him quit out of Outlook, and go
back in after making sure his Outlook process was killed, and it started
connecting again immediately.

My first thought was that Campaign was screwing up connecting, maybe a
network error or something, and the program marked it as a problem and quit
trying, but after the Outlook incident, I'm starting to wonder if there's
something on the iMS side of it.

Even if the two issues aren't related, has anyone seen any kind of problem
with iMS handling high volumes of incoming traffic and just start ignoring
POP connection requests?
