Hi all, I think I may have found something broken in the postfix package. I am using the retail version of SuSE 10.0, postfix-2.2.5-5, but I suspect the opensuse 10.0 behaves the same. I think cidr maps may be broken. There is a shell transcript below that illustrates it. The same commands work just fine on the SuSE 9.3 box that I have been using up to now. I had a quick look at the src rpm. There were a couple of patches in there called dynamic_maps.patch and dynamic_maps_pie.patch. I was wondering if they might be responsible? I will try recompiling the src rpm with those patches removed and see if that helps. Maybe most people don't used cidr maps so this went unnoticed? Note: In the transcript below, smtpd_helo_restrictions_mynetworks, smtpd_helo_restrictions_195_224_204_206, smtpd_helo_restrictions_microbus_nets, smtpd_helo_restrictions_80_176_186_173 and smtpd_helo_restrictions_others are smtpd_restriction_classes that I define locally but you can that just about anything on the right hand side of the map and postmap program should not care. --------------------------------------------------- deposit:~ # cat /etc/issue Welcome to SUSE LINUX 10.0 (i586) - Kernel \r (\l). deposit:~ # rpm -q postfix postfix-2.2.5-5 deposit:~ # postmap cidr:/etc/postfix/cidr_scr postmap: fatal: dict_mkmap_func: unsupported dictionary type: cidr: Is the postfix-cidr package installed? deposit:~ # cat /etc/postfix/cidr_shr # This is a CIDR map # # generate map with: # # postmap cidr:/etc/postfix/cidr_srr # # What about IPv6 ? # currently IPv6 addresses -> smtpd_helo_restrictions_others 127.0.0.0/8 smtpd_helo_restrictions_mynetworks 195.224.204.205 smtpd_helo_restrictions_mynetworks 195.224.204.206 smtpd_helo_restrictions_195_224_204_206 195.224.204.200/29 smtpd_helo_restrictions_microbus_nets 80.176.186.173 smtpd_helo_restrictions_80_176_186_173 80.176.186.168/29 smtpd_helo_restrictions_microbus_nets 0.0.0.0/0 smtpd_helo_restrictions_others ::/0 smtpd_helo_restrictions_others deposit:~ # postconf -m btree cidr environ hash ldap nis pcre proxy regexp sdbm static tcp unix deposit:~ # ---------------------------------------------------------
