First of all: smtp auth is _the_ answer indeed :) But if it gets to a new feature, I think this is how it could work:
The actual check would be: check all fqdn-s in the dyndns_whitelist and get their IP. If any of them matches the source IP, it gets whitelisted. The problem is that this would be very resource consuming. Spamdyke already does a nice amount of DNS requests and even with a few items on this list, this can double, triple, etc. the number of requests. The only way that this could work would be a centralized solution similar to the recipient system due to come in 5.0.0. At least this is my 2c :) Regards Bgs Sam Clippinger wrote: > SMTP AUTH is definitely the best option, if you can configure postfix to > perform it for outbound email. > > I don't use DynDNS myself -- what would be required to support it? > Would spamdyke need to find the IP address(es) of a (list of) DynDNS > name(s), then add those IP address(es) to the whitelist?
