The mail-filter/postsrsd-1.4 package ignores 2 config options from /etc/conf.d/postsrsd due to them being explicitly set at the beginning of /etc/init.d/postsrsd: SRS_DOMAIN=`postconf -h mydomain || true` SRS_EXCLUDE_DOMAINS= To restore correct behavior and allow configuration via /etc/conf.d/postsrd the following could be used (as a direct replacement) to apply these values only in case of them not being set already: SRS_DOMAIN="${SRS_DOMAIN:-`postconf -h mydomain || true`}" SRS_EXCLUDE_DOMAINS="${SRS_EXCLUDE_DOMAINS:-""}"
Fixed in postsrsd-1.4-r1. Thanks for reporting!
