[Dovecot] Dovecot sieve and duplicate email subjects
Hi,
I'm running a small email server with the help of iRedMail.
I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder.
I have an email account setup to receive automated tasks.
Some of these "alerts" occur too often and they have the same subject line, but different senders.
This is the rule I am currently using:
##CODE START##
rule:[AutoAlerts]
if anyof (
header :matches "Subject" "AutoAlert Type1*",
header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*"
)
{ fileinto "INBOX.AutoAlerts"; stop; } ##CODE END##
I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ?
Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder.
Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve.
Thanks very much for your input.

It is currently not possible to maintain some sort of custom state information between deliveries, i.e. Sieve invocations. There is the unofficial vnd.dovecot.duplicate extension, but that uses the message-id exclusively and (currently) cannot be used to track duplicate subjects.

Ok.
Thanks very much for your response!

Although the above is still not possible with the standard Sieve features, I updated the Dovecot-specific vnd.dovecot.duplicate extension with support for the scenario you describe. Basically, I made it much more flexible for checking all kinds of string value duplicates and not only strictly based on the Message-ID header. Also, the user can now directly control the time frame within which duplicates are detected (within configurable limits).

It will be included in the next Pigeonhole v0.3 release.

Stephan.
