For similar purpose I used to use .qmail based system: the script started from .qmail when a message to some special address arrives, the script checks the digital signature on the message, compare the first line with stored counter (to avoid replay attacks) and executes the needed command. The positive side of this technique is that it is very simple (just few lines to code), does not need to open a port (and so it is firewall-friendly, no need to talk with sysadmins, ...), very unlikely to introduce security holes (qmail has quite good records, and in my case the mail was needed anyway). -- Regards, ASK P.S. If the moderator is troubled with spam let us agree on some special word in subject so that he can automatically reject the messages which do not have it.
