Right. The cache is not specific to mysql, but is a feature of the trivial-rewrite transport lookup. This is only likely to be noticed when you use mysql-based transport_maps and a high percentage of the queue is for a single destination. This is not configurable. The workaround is to use a hash: or cdb: table, which triggers a restart of trivial-rewrite upon changes -- but note that frequent restarts of trivial-rewrite may be bad for performance. -- Noel Jones
