[Alpine-info] Filter patterns and whitespace

[Ferdinand Goldmann via Alpine-info]

Hi,

wanted to filter out annoying spam mails using a filter rule on the domain of
the spam sender. The spam mails From fields all have the format of

From: Annoying Sender at foo.host.com

where the "@foo.host.com" part is always the same.

It turns out that a rule filtering for foo.host.com does not work. I assume the
problem is the single blank/whitespace between "Annoying" and "Sender".

Is there any possibility to filter such mails? Or should I rather ask the spam
senders to politely use a valid RfC compliant format for their From addresses? :-)

Regards
Ferdinand
