Inclued "message export to a OS folder" into rules

Due to there is no api available for em client that makes me able to access stored messages by an external tool it would be nice to get at leaste the posibility that incoming messages become stored outisde the em ecosystem, so they become accessible for programmers. Even an api would be much more useful for buisness use the posibility of the automisation of en mail export would be an easy way for private programmers to handle mails. The export function is already available and the rules function too. So why not just combine both until api is offered? 

Right! So a Rule that allows the Save As (same as Export) option. Could be useful Frank.
