ACL / string expansion question

Post #1 of 3 (678 views)

in my RCPT ACL, I'm trying to accept mail bounces for lists I have,
regardless of how broken the sending mail server is, so I'm trying to add a
an accept ACL like this one:

accept domains = +local_domains
condition = ${extract{1}{-bounces+}{$local_part}{false}}

The RCPT I'm trying to match is:
Envelope-to: <svlug-bounces+lsann=hotmail.com@svlug.org>

Ideally, I'd like to get 'svlug' out of it if the match is successful so
that I can then check that svlug is a valid list before I accept the RCPT.

Unfortunately, my condition doesn't seem to work:

rcpt to: <svlug-bounces+lsann=hotmail.com@svlug.org>
>>> using ACL "acl_check_rcpt"
(...)
>>> check condition = ${extract{1}{-bounces+}{$local_part}{false}}
>>> = false

Suggestions?

Thanks
Marc

I look at it some more, is the problem that extract can only use one
character as the separator (i.e. that "-bounces+" is not valid)?

Correct. "Extract" uses one-character separators. You will have to use a
regular expression (${if match...).
