Hi
We have had several instances of the repeating email syndrome and it seems
to be from all flavours of mail servers including Lotus Notes Release 5.0.3
(Intl) and MS Exchange which are being used for both incoming and outgoing
mail. Not to sure that this information helps though.
Thanks
Steve

i take your point on packetloss / truncated SMTP conversations. however,
i'm seeing this from many different domains, including hotmail and yahoo.
one oddity: so far, the dups all seems to come from domains that are using
qmail for outgoing mail.
