Hi,

how to put in filter or block certain types you have help me get rid of a lot of strange stuff but I get at least a 100 per day of emails like this....

[email protected]
[email protected]

Can we or is there a way to blacklist emails that have a bunch of digits in the email.... it not only form @car it is from a lot of emails with numbers...

Thanks

These emails, they are always 4 or more numbers, and after the @ ?

Yes I have not seen 2 or 3 yet

OK, this is a simple filter at this stage, I expect we'll need to tweak it as more examples come in.

But looking in the FROM field, for REGEX
@.+[:digit:]{4,}

That's looking for 4 or more consecutive digits after the @ in the From field.

Wow you really know your stuff we will test it and see if it works... I thank you

Well here it is maybe there has been more but....it only has 3

No worries, just change
@.+[:digit:]{4,}
to
@.+[:digit:]{3,}

Thank you again I was going to do that but I figured I should ask you...

No worries at all

Well I just got a boat load of emails and it caught all of them...

Great. As a safeguard you might want to add a rule to that filter, beside Add Rule click the drop down arrow and select Spam Tool Rule >> set it to be "Sender is not on my Friends List' >> and change the filter to match ANY to ALL rules.

Just in case you have any contacts with digits in their domain, then the filter will ignore if their are on the list.

It worked great this morning will do on you last post your so smart !!! I really thank you..

Went from 250 Emails in the morning to 32 no spam....Thank you...

Great, glad it's working out.
