I should add that such duplicity should not happen when using aliases.
Also, it may happen that two people get different copies of the same mail
(e.g. from this list).
Are you sure your duplicities can't be fixed other way?
In what way ? check alias expansion ?
The thing is I have some groups say group1 group2 and group3
there may be users that are part of only one group but there are others
that maybe in all groups .
Until I implemented lmtp and duplicate supression from it (dovecot) a
user who was in all 3 groups
would receive the message 3 times (and if send to his own email address
4 !) The problem persists
even with lmtp and messages that don't have Message-ID in header ( I
guess this is the criteria for supressing
duplicates) .
How can I track down this ?
Thanks for your time
