SRS Encoding cannot be done

Question

Hi,
We have messaging server 6.3-8.03. Because of our users who use Mail Forwarding facility in sun java system communication express, our server has to send outgoing mails which have envelope from: addresses those don' t belong to us. Most server administrators like Yahoo' s use spf and normally these mails don' t pass spf check. Because of lots of mail from us to Yahoo like these, Yahoo blacklisted us and doesn' t accept any mail from us(sends 4xx error messages in every try) including mails which are not forwarded and normally which can pass spf check.
To be able to pass spf checks, after some research i learned that messaging server has srs support. In 819-4428 it is written that, in order to do srs encoding we need to add SRS_DOMAIN, SRS_SECRETS and SRS_MAXAGE to options.dat file; sourcesrs, destinationsrs, and addresssrs to tcp_local channel. Although we wrote these keywords to our configuration we saw that there is no envelope from: address change in forwarded mails.
Our configuration is:
mappings file:+
+...+
+...+
INTERNAL_IP
+$(193.255.244.136/32) $Y+
+127.0.0.1 $Y+
*  $N
+...+
+...+
options.dat file:+
+...+
+...+
USE_REVERSE_DATABASE=4
+...+
+...+
SRS_DOMAIN=ogrenci.selcuk.edu.tr
SRS_SECRETS=testtest
SRS_MAXAGE=14
imta.cnf file:+

+...+

tcplocal.filter file:_+
require ["regex", "jettison", "envelope", "addheader"];
+if header :regex ["Subject"] "^{Spam\\?}" {+
+jettison;+
+stop;+
+}+
+if header :regex ["Subject"] "^{Mpam\\?}" {+
+jettison;+
+stop;+
+}+
+if allof (+
+not envelope :matches "from" "*@ogrenci.selcuk.edu.tr*",+
+not envelope :matches "to" "*@ogrenci.selcuk.edu.tr*"+
+)+
+{+
+if header :matches "sender" "*"+
+{+
+addheader "Resent-Sender" "Selcuk_Unv_Mesaj_Aktarma_Servisi <[email protected]>";+
+}+
+else+
+{+
+addheader "Sender" "Selcuk_Unv_Mesaj_Aktarma_Servisi <[email protected]>";+
+}+
+}+
NOTE 1: The purpose of tcp_local.filter file is to add a sender or resent-sender header (which has a domain part that is our server is authoritative to send mail as) to forwarded mails plus prevent sending spam mails out.
NOTE 2: We didn' t forget to compile configuration after these changes(imsimta cnbuild, imsimta restart, stop-msg, start-msg)
Any ideas about why server doesn' t do srs encoding? Is there something forgotten or any misconfiguration in our configuration, or something forgotten to be written to book 819-4428 by sun?
Thanks a lot.

You can upgrade to MS7 update 2 by using the "./commpkg upgrade" command with Communication Suite 6 update 2 (http://wikis.sun.com/display/CommSuite6U2/Get+the+Software).
