Re: Problem with aliases

Thanks for your answer Dan

1.I removed the space on the test alias. Address [email protected] is just fake
for this email.
2.The problem is that I'm not write a email to  [email protected],
but the spammers send email to address [email protected]. I'm
writing an emails to address [email protected].
3. I'm just afraid why owner-test did apperar in the logs

I don't know how to prevent delivery of mail to test-list, except from
the local alias expansion of test. 
Cause:
I use postfix with virtual users stored in mysql. Only majordomo aliases
are stored in local alias table. I cannot use virtusertable.I forgot to
describe one problem.
I have domain @test.com. I set in my virtual alias ( according to
http://www.postfix.org/VIRTUAL_README.html ) in my virtual table( or
file, it doesn't matter )
[email protected]         test  , and in my alias is

test             "| /usr/local/majordomo/wrapper resend -l test
test-list"
test-list        :include:/usr/local/majordomo/lists/test

But spammers sent an email directly to [email protected] and it
means, postfix looked directly to alias table ( not virtual table ) I
tried to use in my virtual table this;
[email protected]   error:nouser User unknown,  and it works for
the message to [email protected], but it doesn't work for correct
mailing list [email protected], cause when 
[email protected] pass message to test-list ( postfix looks again to
the virtual table ) and send message not to
:include:/usr/local/majordomo/lists/test but to error:nouser User
unknown

Thanks for an advices

#1.  You have a space (shouldn't matter) after "| on the test alias.
	I assume [email protected] is fake for the purpose of this email,
	if not, you better own/control delivery to [email protected].
#2.  If you write to [email protected], you are bypassing majordomo.
	The correct address for your list is [email protected] #3.  Your
log shows owner-test sending mail to test-list locally. uid-1003
	The message was never "To:" owner-test as you imply in your
final
	question.

Something is really hosed, as I do not see from the information provided
how test-list can get translated to test, unless your test.config file
or the test file itself reference the test@ address.  Mail should be
composed "To:" [email protected], which gets processed through majordomo,
then resent to the alias [email protected] when all the rules pass
inspection.  The test-list alias in turn evaluates to the contents of
file /usr/local/majordomo/lists/test and uses postfix/sendmail to
deliver to all those addresses.

You need to prevent delivery of mail to test-list, except from the local
alias expansion of test.  Anyone writing to test-list will bypass
majordomo and the rules/policies in test.config, and have full access to
your list of users in the "test" file.
