I believe the generally accepted regex is: ^From .+ (that's "^From" followed by SPC, followed by ".+"). The date format can be variable from client to client, and as we've seen on mutt-dev in the past IIRC, may be omitted entirely by some clients / MDAs. This is why most clients / MDAs will escape lines that start with "From" or use quoted-printable to encode messages containing them. Sadly there is no official standard which defines what should be in the From line which starts an mbox message, as there is no single formal standard for mbox message stores (there is RFC 4155, which is NOT for message stores -- otherwise you get whatever your vendor decided to implement). -- Derek D.
