Hey- I 99% use Pine, too.
But I think the issue is your leading "*" in your recipe; these aren't "glob"-type expressions, they're full regular expressions, and as such that "*" means "0 or more of the preceding match character", which in your case is the space.
I think:
Code:
:0:
* ^From:.*lan.com$
/dev/null
... will work, but for safety while testing change "/dev/null" to a folder so you don't inadvertently end up trashing
all your mail.
