Can I try anyway?
Assuming you have something like the default config file, your lsearch looking isn't looking up anything and all of the work is being done by the :blackhole: in the aliases file. It's simply being bit bucketed with sender thinking that the message made it. If you just want to fail certain addresses, you can still use the alias file which will be trigged on the "verify = recipient" line of your rcpt ACL. Use something like peter: :fail: This person no longer works here They are both just linear flat file searches so they are equally fast/slow depending on the file size (1000+ entries and you probably look into making them into a db4 file instead). If you still really want to do it with an lsearch, you'll want to see what is really happening when the mail is coming in. Best way would be to fake an SMTP session and use the "exim -bh 11.22.33.44" command line to debug what exactly is happening. When you run that command the program will treat you like the supplied IP, so you have to do the HELO, MAIL FROM:, RCPT TO:, etc stuff. You best bet for getting this working is to keep reading the lsearch part of the manual as it has a lot of options.. the only thing I use it for, in combination with "recipients = " is a @@lsearch of a file in the form of domain.com: person1,person2,person3 domain2.com: person4,person5,person6,person7 The @@ is a special case lookup. I use that particular search to collect all my spamtraps from multiple domains into the one account and "control = fakereject" them.
