As it seems that cyrus doesn't support the notify example scripts in the contrib directory anymore I have come up with a workaround: All Mail to *@sms-gateway.internal is piped to an external shell script which sends the mail as sms (the user part is used as the number). Just define a new mailtransport in /etc/postfix/master.cf . I'm using postfix as the mta but I'm sure sendmail can do the same. Now forward important mail by sieve to the address [EMAIL PROTECTED] in addition to any other archiving sorting etc. If anyone is interested I can supply the script and a more detailed description.
