exclude from freemail_domains

Good afternoon list.

is there a way to exclude a domain from the fremail_domain checks in the
local.cf?

I do not want to have to manually remove our domain (which does not
offer freemail) from the 20_freemail_domains.cf file every time we update.

refer to bug 6542

http://old.nabble.com/-Bug-6542--New%3A-Freemail_domains.cf-FP-td30899122.html

our own mail is matching:

FREEMAIL_FROM
FROM_MISSP_FREEMAIL

thanks in advance.

afaik you can't disable a domain atm but you could use a rule doing
something like (untested):

header NICE_ENVFROM_YOURDOMAIN
eval:check_freemail_header('EnvelopeFrom', '\@YOUR_DOMAIN')
describe NICE__ENVFROM_YOURDOMAIN Envelope-from YOUR_DOMAIN
score NICE__ENVFROM_YOURDOMAIN -100

score is just an example...

Is your domain vodamail.co.za or are you just offering that bug as an
example of the class of the problem?

And by "our domain" do you mean "the domain we own and administer" or "the
domain our ISP uses"?

If that domain does not offer free email or webmail services then the
listing is incorrect and should be removed.

If the domain _does_ offer free email services, then the listing is valid.

Question: is the problem that you yourselves are in a domain that is
included in the freemail list, and the rules are hitting on message from
that domain to you? It's possible that the freemail rules should have
someoffsetting tests for from_dom == to_dom.

So the outbound servers, which use SpamAssassin, are hitting the rule
mentioned.

As such, a lot of our clients outbound mail are being rejected.
It is a GSM network and a lot of mail is being sent via handsets.

Why don't you just disable FreeMail plugin? I don't see why you would need
it on outbound mail. Unless you share the same SA for incoming or expect
your users would be some 419ers forging Reply-To: etc..

In any case I think it is valid to open up a bug so we can implement the
"unlisting" config feature for FreeMail plugin.

Hi Tom,

FREEMAIL_FROM by itself is harmless. However, if your e-mail is also
hitting FROM_MISSP_FREEMAI, it means it has malformed From: headers.

Something like:

From: "Lawrence Williams"lawrencewilliams [at] nl

Notice the missing space between the quotes ending my name, and the
beginning of the e-mail address.

A proper From header would be:

From: lawrencewilliams [at] nl
or
From: "Lawrence Williams" lawrencewilliams [at] nl

This is most likely a bug in the e-mail system you are using.

Regards,
Lawrence

Thank you to everyone who has responded.

I will do some tests and will advise on the action which brought about
the desired result.

Keep up the good work guys.
Much appreciated.

Afternoon list

The rule which brought about the desired result is adding the following
to the local.cf file

ifplugin Mail::SpamAssassin::Plugin::FreeMail
freemail_domains example.com
freemail_whitelist example.com
endif

replace example.com with the problem domain.

Thanks once again for all the responses.
