[Dovecot] Auto forward virtual users mail using Sieve

[Julian Baker]

Hi Stan

Thanks for the response, please excuse the noobieness

If I add the domain to Exim's domains then email never gets to  
Roundcube (and therefore I presume Dovecot), which defeats the  
client's purpose'

If I can find a way to make Dovecot automatically read a sieve script  
in the (virtual) users mail directory then I can figure the rest.

Kind regards
Julian
