Currently an expiring autoreply needs a sieve master user configured for "sogo-tool update-autoreply".

Since it is not obvious how to do that in a very secure way, it may be better to expire autoreplies in the sieve script itself, e.g.

require ["date", "relational", "vacation"];

if currentdate :value "le" "date" "2023-01-28" {
vacation "I'll be back on the 28th";
}
