add sieve support for Thunderbird

[usul]

Would be nice to be able to edit sieve filters from within Thunderbird.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Rooting for this idea since the recommended plugin doesn't seem to be working any more on current versions of Thunderbird.

[valheru]

I would love to have this!

[HecateRaven]

I want it too

[JeffInTx]

Another vote for yes!

[Timbudong]

I upvote too!

There was good idea to add calendar.  Now time for sieve scripts:

1.) autoresponder

2.) filter/move mails on the server side

Having Thunderbird to support the Sieve protocol would be really great to see!

There's an old bugzilla issue with a very old POC at https://bugzilla.mozilla.org/show_bug.cgi?id=79525

Yes, please, add support for ManageSieve protocol (RFC 5804) to Thunderbird. It would be really helpful.

[ilo2]

It would be very useful, I support this idea!

Thunderbird needs to support Sieve protocol.  This would be extremely valuable.

I really was upset when I realized I'd had to use a "SieveBridgeClient" when wanting to use the only sieve plugin existing for TB >=128...  No! sieve should be possible *directly* - with or without plugin - I don't care. But if it's forbidden for plugins to communicate directly to external ports it should be integrated into the package. This may be a positive signal to other hosters to enable sieve for customers - maybe not the really big ones...
Sieve is important, and would be nice to be able to use it also on mobile devices.
Thank you.
