In other words, your recipe is being used, but the pattern you give
\ndoes not match the incoming mail.\u00a0 I think you are hoping that “^FROM”
\nis a special procmail expression, like “^TO”, “^FROM_DAEMON”, and
\n“^FROM_MAILER”;\u00a0 unfortunately, this is not the case.\u00a0 What you meant
\nis probably:<\/p>\n
* ^From:.*jane<\/p>\n
However, that would catch mail from “joe@janet.com”, which is
\n^^^^
\nprobably not quite what you want either.\u00a0 Perhaps<\/p>\n
* ^From:.*\\<jane@cs\\.concordia\\.ca\\><\/p>\n
would fit the bill.<\/p>\n
What it means is:<\/p>\n
*\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Start pattern.<\/p>\n
^\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Match at beginning of a line; i.e. the next
\nword or symbol must occur at the start of
\nthe line.<\/p>\n
From:\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Match the word “from” (upper or lowercase
\nor mixed), followed by a colon.\u00a0 That’s the
\n“From:” header.<\/p>\n
.*\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Match anything (zero or more “wildcard”
\ncharacters);\u00a0 this will eat any “comments”,
\nsuch as the person’s full name, etc., and
\npossibly the space after the “From:”, though
\nthe last non-alpha, non-digit character
\nbefore the start of the thing you want to
\nmatch will be eaten by…<\/p>\n
\\<\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Match a “word delimiter” character
\n(anything except a letter, digit, or
\nunderscore) or a newline — this avoids
\nmatching on, say, “jbjane@cs…”.<\/p>\n
jane@cs\\.concordia\\.ca\u00a0 Match your target address, where dots are
\n*not* wildcards but match real dots.\u00a0 You
\ndon’t *have* to escape the dots, but if you
\ndon’t, you might accidentally match
\n“jane@csxconcordiaxca”, which is not what
\nyou want.<\/p>\n
\\>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Now match a word delimiter or a newline
\nagain; this avoids matching the unlikely
\n“jane@cs.concordia.cam.org”, for example.<\/p>\n","protected":false},"excerpt":{"rendered":"
