I'm trying to implement SRS in my setup, using:
http://www.openspf.org/SRS
and the 'srs' debian package. Because i'm doing some test and i've not big
email flow, i'm implementing running directly the script, and not using the
'daemon/socket' mode.
Also, i want to use it only when i forward the email using forward data from
an LDAP database (mailRoutingAddress, old 'laser' schema). At least for now.
My current setup is:
SRS_SECRETFILE = /etc/exim4/srs_secret
SRS_HASHLENGTH = 8
SRS_DOMAIN = ac.test.it
[...]
user_ldap_redirect:
debug_print = "R: user_ldap_redirect for $local_part@$domain"
driver = redirect
domains = +local_domains
.ifdef LOCAL_MAILHOST_NAME
condition = ${if eq{\
${if eq{${lookup ldap {LOCAL_MAILHOST_LDAP_ROUTE_QUERY}}}{}\
{DEFAULT_MAILHOST_NAME}{${lookup ldap
{LOCAL_MAILHOST_LDAP_ROUTE_QUERY}}}}\
}{LOCAL_MAILHOST_NAME}}
.endif
.ifdef SRS_SECRETFILE
address_data = ${run{/usr/bin/srs --secretfile=SRS_SECRETFILE
--hashlength=SRS_HASHLENGTH --alias=SRS_DOMAIN $sender_address}{$value}{:fail:
SRS failure}}
errors_to =
${quote_local_part:${local_part:$address_data}}@${domain:$address_data}
headers_add = "X-SRS-Rewrite: Sender address rewritten from <$sender_address>
by $primary_hostname."
.endif
data = ${extract{1}{:}{${lookup ldap {LOCAL_USER_LDAP_REDIRECT_QUERY}}}}
check_ancestor
And seems to work, using 'exim -d -bhc':

But still the sender of the email is set to '[email protected]'. What i'm missing?
Thanks.
