why not delete this kind of email since it's known to
be a spammer tactic?
We're having this problem as well in addition to VERY high memory usage
for smtpd32 running 2006.03. By VERY high I mean 800 MB's for smtpd and
we're having to restart it daily!

spammers typically do is connect to the SMTP server, flood their data
to SMTP then close the connection after sending the "." (they don't
wait for the 250 OK from SMTPD). Since STMPD can not give the client
a 250 OK the message has not been accepted for delivery and is not
delivered (a proper client will resend the message later since it
didn't get the 250 OK). In this case it is left in the spool as a T
and D file. We are looking into why SMTPD does not clean up the T and
D file.

Subject: [IMail Forum] Stuck in Spool
We use an external company (Myriad Networks -
http://www.myriadnetwork.com) to take over our mail delivery in the
event our server is down. It is used as our secondary MX record. The
problem we are having is that many of the messages sent from Myriad to
our Imail server get stuck in the spool. We don't have this problem
with any other domain. There are hundreds of A, D and T files in the
spool. They are all sent from Myriad. Most (if not all) are spam, but
I'd still like to figure out why these messages are not being
delivered. Has anyone experienced anything similar with an external
company handling secondary mail delivery?
All the messages are received within a minute or two of each other
(there are perhaps 10 of these groups where 40 messages are delivered
at the same time - for example 40 messages at 7:38am, 40 at 11:32am,
etc). The logs for these deliveries all stop at "performing antispam
checks". In the declude log, the message are uniformly HELD. Does
that mean they are just left in the spool?
Imail 8.21, Win2000
Thanks
