debian/postfix-ldap.postinst: if [ $(postconf |grep alias_database | awk '{print $3}'|awk -F \: \
debian/postfix-lmdb.postinst: if [ $(postconf |grep alias_database | awk '{print $3}'|awk -F \: \
debian/postfix-mysql.postinst: if [ $(postconf |grep alias_database | awk '{print $3}'|awk -F \: \
debian/postfix-pcre.postinst: if [ $(postconf |grep alias_database | awk '{print $3}'|awk -F \: \
debian/postfix-pgsql.postinst: if [ $(postconf |grep alias_database | awk '{print $3}'|awk -F \: \
