I want to traverse a filesystem and copy parts of it to another filesystem by creating symlinks instead of copying anything.
rsync would be ideal if it had something like a --local-copy-via-symlink option, because rsync's inclusion/exclusion filters would be the best way to specify what I want to copy.
I know I can do this with a script, but is there a clever command that does this already?
Suppose I have a line like this in my /etc/aliases:
foo-bar: "|/etc/smrsh/some_script"
some_script is being run as user mail, but I need it to be running as user nobody.
I'm using procmail as the local delivery agent, and the system is some bastardized RHEL.
How can I configure sendmail or procmail to do what I want?
I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script.
I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error.
So here's a specific example:
I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address.
Here's the sort of SMTP session I need:
220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT)
HELO blort.foo.com
250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you
MAIL FROM: <[email protected]>
250 2.1.0 <[email protected]>... Sender ok
RCPT TO: <[email protected]>
250 2.1.5 <[email protected]>... Recipient ok
I tried some stuff with regex maps, but I never got past 550 user unknown.
