Re: Still having mutiple delivery problems.

[Daniel Kelley]

i am having the *exact* same problem.  it only happens with mails
originating outside our domain, and tehre's no rhyme or reason to it.  
our logs do show 

seems to happen more often with hotmail and yahoo.  it's also happend with
this list!  the only constant i can see between the three is that they all
(i think) use qmail for outgoing mail.  

i can't comfirm that this has happend at all when the mail server is
anything but qmail.  how could this be the common link?

Are you seeing this as SMTP level?  We get duplicated messages frequently
but it's always (as far as I can tell) a pop issue.  It is always solved by
deleting an improperly formatted multipart mime message, almost always
from outlook.  The logs show somthing like "unable to lock mailbox; connection
lost" or something similar.  That's with cucipop.

Re: Still having mutiple delivery problems.

[Daniel Kelley]

aha!  we use cucipop as well.  there's only one 'error locking' message in
the logs, but there are plenty of these:

cucipop[20914]: Invalid command capa - -

i've tried to figure out what this means, but i have no clue.  could this
be indicative of what you're talking about?

if outlook clients are sending messages that cause this, what steps can be
taken to prevent it?

thanks-

It looks like this:
Mar  5 18:02:29 gray cucipop[15401]: Error locking hwware's mailbox 
Mar  5 18:02:29 gray cucipop[15401]: lost hwware 208.148.249.48 240, 16 (752895), 0 (0)

Note that this is a client issue, not qmail.  You need to find out
what "getting delivered multiple times" **really** means.  Get the headers.
Anytime anyone uses passive tense to describe what is going on - red flags.

RE: Still having mutiple delivery problems.

[Kep Brown]

For my site it is not a pop issue.

The progress for a message is as follows. (taking mail from our co-lo as an
example but it happens from multiple external systems)

Process on App Server attempts to send an email in house using a mail server
at our co-lo.

External Email Server
Co-lo mailserver attempts to deliver the message in house recieves an looses
connection while sending end of data.
Co-lo mailserver then waits 30-90 minutes and attempts to deliver the
message again, recieves the sam error repeats process for 2 days until it
gives up.

On the internal side.
Email server accepts connection and delivers the message normally, 30-90
minutes later accepts the same message and redelivers it normally.  Meaning
no errors in Maillog or Messages.

ok, i'm now pretty sure that this is a qmail/SMTP issue:

in examining the mboxes of those affected, they each have many copies of
the duplicate emails, so it's not the case that cucipop is simply
making it appear as if they have received the message 100 times;  there
are actually 100 copies of the mail in the box.

the date sent is identical on every message, but the message is actually
being received many times by qmail on our end.  

here are two examples of the exact same message being delivered twice
(from this mailing list).  i know that qmail tries to verify delivery, so
some situation must exist where my qmail installation is not providing
that confirmation to the remote mailserver.  

here are the messages:
