    We've been running the perfect spamsnake for about 8 months on ubuntu 8.04 we're mostly happy with it excluding a couple of issues we're working on in another thread.

    We've been using the relay_recipients file with just the domain in OK

    But have now sorted out the scheduling of exporting the 8000 email addresses from our exchange box over to the spamsnake, so I tried filing the relay recipients file with the 8000+ emails all with a space and OK at the end, ran postmap /etc/postfix/relay_recipients and even gave postfix a restart.

    even with that done we still see emails to <anyone> getting through even though those email addresses are not in the relay_recipient file.

    Am i missing another step or using the wrong file even?

    Stupid question but have you commented out OK? If you didn't, that would be your reason why emails are still going through.

    Yes, I renamed the original relay_recipients to relay_recipients.old then created a new file with all the emails in and did the postmap on the new file.

    Although I've not yet had a good look through the traffic this morning, as of midnight last night there was a significant drop in traffic, I'll try to look through to see any email addresses that shouldn't be there

    Ok, having had a quick look through the recent messages, emails are still flowing to addresses not in my relay_recipients file, although it's not the end of the world it would be nice to tie this one down.

    Make sure to delete the relay_recipients.db file also and then repostmap your new relay_recipients file so that it recreates the db file.

    Restart postfix and you should be good to go.

    Well, I did as advised, deleted the relay_recipients.db file deleted all versions of my relay_recipients file to ensure I didn't use the wrong one, then added the 8200 email addresses to a new relay_recipients file, ran "postmap /etc/postfix/relay_recipents" restarted postfix and for good measure even restarted the server.

    After a few days of testing I can confirm that <[email protected]> still comes through, but oddly, it is only that get through so it is filtering against the domain name, just not the full email address.

    Please post your

    The reason it's only allowing your domain to pass through is because it's defined in your relay_domains file.

    Hi Rocky, Thanks

    Below is my as requested, i've swapped out my actual domain name for '' and my IP for '123.456.789.0'

    I've noticed there is no reference in this file to a relay_recipients hash, i think this could be the problem! -->

    You are correct and it confirms what I thought was the problem.

    Insert this into your

    relay_recipient_maps = hash:/etc/postfix/relay_recipients or the name of your relay recipients file.

    Then reboot postfix and you should be good to go.

    Thanks Rocky

    I believe that has sorted it, now all that's left is cleaning the database but more RAM should fix that one.

    Thanks again for the great spamsnake and your assistance getting it sorted.
