dhanna Posted March 26, 2004 Share Posted March 26, 2004 I have added some domains, not email addresses, to my blacklist, but it does not seem to be blocking my choices. What is the proper syntax? I want to block a couple of domains. is it *[at]comcast.com , comcast.com, *.comcast.com or what? Can you also block IPs? Thanks Link to comment Share on other sites More sharing options...
StevenUnderwood Posted March 26, 2004 Share Posted March 26, 2004 comcast.com is the correct format Link to comment Share on other sites More sharing options...
cats Posted March 31, 2004 Share Posted March 31, 2004 comcast.com is the correct format According to the instructions the personal blacklist uses the Return-Path field. How do I blacklist messages with "<>" as the Return-Path? I'm getting several of these a day. Link to comment Share on other sites More sharing options...
dhanna Posted March 31, 2004 Author Share Posted March 31, 2004 Hmmm... I was told that blacklist actually resolve the source and then blacklist from there. Was I told incorrectly? Link to comment Share on other sites More sharing options...
StevenUnderwood Posted March 31, 2004 Share Posted March 31, 2004 There are 2 different blacklists at work here. The one being discussed here is the personal blacklist available in webmail (along with a personal whitelist) and those only work with the email address of the sender. I was under the impression that both the From and Return-Path fields were used in looking for a match, but cats is correct that the description does mention that only the Return-Path is used. There have been requests to expand the capabilities of the personal white/black lists to include other fields, but they have not been implemented as of yet. A standard DNS Blacklist like spamcop does indeed look at the IP address of the sending server to determine if it is blocked. In this way, a person can receive messages they want from a DNS blacklisted server by using their whitelist. For instance, the only SMTP server for foo.com is on the spamcop blacklist. You have a friend who uses foo.com for their ISP. You whitelist the address user<at>foo.com and any message except from your fried will be blocked. If you whitelist foo.com entirely, the spamcop blocklist for that server is over ridden. Link to comment Share on other sites More sharing options...
