Exim filter for specific requirement

[Source1]

We need to create a forwarder containing all email addresses of domain.com i.e [email protected] and the condition to apply is only [email protected] & [email protected] should be allowed to send mail to [email protected].

Tried following filter but it's getting applied incorrectly.

if ($h_to: contains "[email protected]" and $h_from: does not contain "[email protected]" or $h_from: does not contain "[email protected]")
then
save "/dev/null" 660
endif

Hello,

Try editing the filter to look like this and let us know if it helps:

#FilterRule
if
 $header_to: contains "[email protected]"
 and $header_from: does not match "^(abc|alerts)@domain.com"
then
 save "/dev/null" 660
endif

Thank you.

This filter doesn't work under Global Email Filters.

Thanks for your reply,

It's getting filtered as below if I give From in this fashion ^(alerts|abc)@domain.com but it works well with single ID i.e. [email protected].

My requirement is to authorize more than 2 IDs to be able to send to [email protected]

~~~~~~~~~~~~~~~~~~~
[email protected] T="test" for [email protected]

Could you provide more details about this? It seems like you may need to develop a custom regular expression for use in your rule.

Thank you.

Hello,

For instance, what's a specific example that's not covered by the filter rule mentioned in my earlier post?

Thank you.

Hi,

I have clearly mentioned what is happening if I create filter using ^(alerts|abc)@domain.com.

Hello,

The log output in that post suggests the actual email address in your filter includes hyphens (- symbol). This is going to require a custom filter rule using regular expressions. Here are a couple of documents you can reference if you'd like to try writing a custom rule on your own:

Exim Filter Specification - String testing conditions
8. Regular expressions

You may also want to post to the Exim users mailing list for additional assistance developing the custom rule.

Thank you.
