I've fixed this by changing the name of the sieve script in the database from
"active" to "main script". I'm a bit confused by this though.

I could see this in the log:

delivery.

So it's looking first for "main script", which is why it now works. But it was
then looking for "dict:proxy::sieve;name=active". Why didn't that work when I have
this in my sieve config?

plugin {
    sieve = dict:proxy::sieve;name=active
}

I also don't understand why it is looking for "main script" rather than "active"
at all, and why things stopped working when I upgraded.

Sorry for all the questions - I'll be happy to update the wiki once I've
understood things better.

Thanks for all your help,

Andy
