Assuming that I have methods to avoid looping at the SMTP level .. how can I do this in cyrus, sieve I would recommend an email autoresponder designed for the job, see: http://en.wikipedia.org/wiki/Autoresponder In particular Today's autoresponders need to be careful to not generate e-mail backscatter, which can result in the autoresponses being considered E-mail spam. I would probably hang something like request-tracker on the sales address, causing every contact to not only get an immediate response, but be trackable from there. Bron.

The moral is, if you need this, the implementation is far from trivial and you will need to implement internal controls and feedback loops to prevent these types of problems. Unless you are legally required to do this, figure out another way. Cheers, Ken Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
