Well, as pcre stands for 'perl compatible re', I would guess it should
be exactly the same.
But the best answer you can get is testing itself by using postmap -q
with that regex pattern and a few test-lines.
I believe a regexp style pattern is almost the same, with only \s
replaced by [[:space:]]
See the pcre(7) and regex(7) manpages for the details.

For pcre style expressions how would you represent the perl pattern
/\s{15,}[a-zA-Z0-9]{2,8}$/? Is it exactly the same in pcre as it is in
perl? How would you represent this in regexp style (for immediate spam
rejection patterns)?

Can anyone suggest the best way to handle this? Are you using regexp or pcre maps ?? If you are using pcre style regular expressions then \t should work. If the map is a regexp style map, then you just use a tab instead of \t. Testing your regular expressions with postmap -q is a great way to find out any problems with the regexes. -- Tot ziens, Bart-Jan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Postfix Regular Expressions
I have simple question that I can't find documented. I need to add basic spam/virus filters to body_checks using regular expressions where the line begins with a tab character. Using "\t" or "\s" doesn't seem to work. Can anyone suggest the best way to handle this? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
