egrep -i "message-id: [<][0-9]{10}[(_dot_)][0-9]{4}[(_at_)]" file(s)
gives me no false hits. The terminal @ appears to be necessary. All the
msgid strings begin with 104??? The second part (just before the @) can be
four or five digits. This also got hits in an old spam folder (Aug 02).
The .rc I'm using is:
N=[0-9]
:0 : #message-id <10digits.5digits
* ^Message-ID:[ ]*<$N$N$N$N$N$N$N$N$N$N\.$N$N$N$N$N@
s_msgidd
(And one for 4digits, of course).
Is there a way to say "4 or 5 digits"? Something like [$N[$N]]@ maybe?
