List, I have looked through the list-archives and although I have seen several threads on the following issue, I don't feel like they were fully concluded, so would like to get an opinion now if possible.
Dspam as a spam filter is working great, and we are seeing good results in our testing. However, we are struggling a bit with getting the accounts to work the way we want them to. My goal is to avoid a massive amount of unnecessary users from being created by spammers who mail to hundreds of made-up [EMAIL PROTECTED] I also want to maintain the ability of users to create special addresses for individual online accounts, such as [EMAIL PROTECTED], but have those map back to the user in dspam so only a single account is necessary for each user. - I have postfix and dspam running with mysql (virtual uid support) on debian. - I have the 'recipient_delimiter = -' set in postfix - I have users who use a lot of aliases such as [EMAIL PROTECTED] - I have virtualmaps in postfix that look like this [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] @domain [EMAIL PROTECTED] # This is to prevent [EMAIL PROTECTED], [EMAIL PROTECTED] etc. - I then have a transport map in place to transport all mail for a given domain to the message-store which hosts it. Here is how I would like it to work: - Postfix sees [EMAIL PROTECTED] and sends it on to dspam. - Dspam recognizes that this is user and not user-amazon and processes it accordingly. - Dspam hands it back to postfix, and postfix delivers it appropriately. I know in dspam, you have 'EnablePlusedDetail' setting. When I set to on, and test with [EMAIL PROTECTED], everything works fine. But it doesn't work with a minus "-" sign. Does anyone have any recommendations for getting around this problem? In the previous threads, some posters mentioned front-ending dspam with a separate postfix instance. I am not opposed to doing this, but would like to see what other options are available. If the front-end method would be best, does anyone care to share how this worked well for them? Regards, Sean
