Block mails sent to a spacific address

Hi

I've exim version 4.69 running on WindowsXP.

This is currently configured as a SMTP transfer agent for a specific application. Exim uses a specific SMTP account on the external hosted mail server with which it just transfers all mails to it.

Now the question is that i need to just block mails from Exim sent to a specific mail address.

I'm not sure how to use filters to do this. moreover my setup is on Windows & most of the document on the internet explains steps for linux.

Please help.

Interesting, I had no idea there was a port to windows.

99% of the steps for setting up exim on linux would apply to windows
except for installation.

Assuming that the email address you want to block is blah [at] example

If the email is being delivered to exim via SMTP and not submitted
locally then placing the following in the rcpt acl section will block
that address.

deny domains = example.com
local_parts = blah
message = This address is blocked

If its submitted locally,
create a file and place the following line into it.

blah: :fail: This address is blocked

Then place the following router at the top of the routers section.

reject_user:
driver = redirect
domains = example.com
allow_fail
data = ${lookup{$local_part}lsearch{/path/to/above/file}}

Re: Block mails sent to a spacific address [In reply to]

Thanks for your response. Actually i'm running Exim on Cygwin in windows.

The mails are submitted locally to Exim.

Other point i forgot to say is that i need to allow mails to all other IDs of the domain example.com except abc [at] example

But I hope the below entry would actually block sending mails to example.com.

reject_user:

driver = redirect

domains = example.com

allow_fail

data = ${lookup{$local_part}lsearch{/path/to/above/file}}

And can I just freez the mail instead of fail

abc: :freez:

It will allow mail to all users of that domain (if they exist) except
the entry in the file.

To use freeze you have to change the allow_fail to allow_freeze in the
router and change the fail in the text file to freeze.

BTW to take out the whole domain just replace
data = ${lookup{ etc
with
data = :fail: This domain is blocked.
or
data = :freeze:

Re: Block mails sent to a spacific address [In reply to]

Thanks Andrew. This seems to work for me. But i get the following error in the Exim log, not sure why.

I think spaces are not allowed between : and freeze, Also a space after
the second colon surrounding freeze might be required, but not 100% sure.

Are you using a file for storage of local parts to reject?
If so, do you have a : at the end of the local part, a space (well at
least one) and then :freeze:
If not, that's where the problem lies.
eg
abc: :freeze:

I have the following entry in my exim.conf at the start of router configuration.

reject_user:

driver = redirect

domains = example.com

allow_freeze

data = ${lookup{$local_part}lsearch{/etc/blockmail.txt}}

In blockmail.txt, i've the following entry - i need to block abc.def [at] example

abc.def: :freeze:

I tried the following too, but the same error in the log.

abc.def: :freeze :
