Re: Subject Regular expressión
hi, Warnign : no regex will work if the subject is encoded, with more and more emoji and UTF8/accents in them your success rate will be low if you do not control the subject type (plain text). regards, Ghislain.

- In the last example you have a caret at the beginning of both Subject and
Reference.
- There is a period a the end between the asterisk and dollar sign. That means
there has to be exactly one character after the last number. Is this a
requirement?
You could simplify it as "Reference No: PP(-[0-9]+)+” unless it is mandatory
that the first group of digits is exactly three characters. If they all are you
could use {3,3} instead of the first plus. You could also use {1,3} if they are
variable length. You can do the same to the second plus as it is the count of
groups including the dash.
(I didn’t test any of these. It’s been a while since I last wrote regexps so I
might be rusty.)

Re: Subject Regular expressión
here again :-( i need match this: Reference No: PP-425-168-292
I use this regex: ^Reference No: PP-[0-9][0-9][0-9]+(-[0-9]+)*.
but not work.
i check this regex with grep, it work fine but in postfix no.
grep -E "^Reference No: PP-[0-9][0-9][0-9]+(-[0-9]+)*.$" test.txt
Reference No: PP-425-168-292
warning: header Subject: Reference No: PP-425-168-292
/^Subject: ^Reference No: PP-[0-9][0-9][0-9]+(-[0-9]+)*.$/ DISCARD
any ideas?

I've been having no luck with a simple regex to match strings with 64 or
less characters.
In a Perl-compatible regular expression, you want something like this:
/.{,64}(your linked profile)/

To restrict the match to strings where the desired pattern is at 64 bytes after
the start of the string, it would have to be anchored:
/^.{,64}your linked profile/
Oops. You're right, Viktor, I omitted the start anchor.

The above is much too cryptic. Perhaps you can state a clear goal and a more
precise question.

Not true - at least for pcre. Just enclose the entire expression in
brackets:
/^Subject:\s*(Hello there|Hey man)/ DISCARD

I'll never praise that tool enough, for Perl regex, it saved my bacon more often than not: The Regex Coach (http://weitz.de/regex-coach/) It works fine under wine. In fact, this morning I wrote a regex using the regex coach, so I could see what it did as long as I was writing it. Best s, Olivier --

There is little cost in doing so. The | operator is supposed to bind to a single token before and after. What I do in such situations is enclose the substrings on each side of the | in parens. As pointed out by another member here the trailing ".*" is unnecessary.

Well to start with, in that regex, both (.*) sub-expressions are completely redundant. But you may be making too many assumptions about whitespace. Your version will work only if there is *precisely one space and nothing else* between 'Subject:' and the text. Try this: /^Subject:.*(Hello there|Hey man)/DISCARD -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958
