Any insight? >Greg The sites are regional exploders for the FreeBSD mailing lists. The idea is that instead of sending 50 or 100 copies of each message into the same region, one or two are sent to the exploder which does the fanout locally. It has a few bumps, but seems to work generally pretty well, and has _dramatically_ reduced the mail load on freefall. The current list is in /etc/mailertable on freefall: # # After editing this file, run (as root) # makemap hash /etc/mailertable.db < /etc/mailertable # # See RFC 1394 for country <--> domain mapping # # Domainname Mailer:hostname # phk@freebsd.org .at smtp8:mail-relay.dk.freebsd.org .be smtp8:mail-relay.dk.freebsd.org .ch smtp8:mail-relay.dk.freebsd.org .cz smtp8:mail-relay.dk.freebsd.org .dk smtp8:mail-relay.dk.freebsd.org .ee smtp8:mail-relay.dk.freebsd.org .es smtp8:mail-relay.dk.freebsd.org .fi smtp8:mail-relay.dk.freebsd.org .hu smtp8:mail-relay.dk.freebsd.org .is smtp8:mail-relay.dk.freebsd.org .lt smtp8:mail-relay.dk.freebsd.org .lv smtp8:mail-relay.dk.freebsd.org .no smtp8:mail-relay.dk.freebsd.org .nl smtp8:mail-relay.dk.freebsd.org .pl smtp8:mail-relay.dk.freebsd.org .pt smtp8:mail-relay.dk.freebsd.org .ru smtp8:mail-relay.dk.freebsd.org .se smtp8:mail-relay.dk.freebsd.org # # # via phk@tfs.com fallback: julian@tfs.com .tfs.com smtp8:mailhub.tfs.com #.mil smtp8:ref.tfs.com #.com smtp8:ref.tfs.com #.org smtp8:ref.tfs.com #.gov smtp8:ref.tfs.com #.net smtp8:ref.tfs.com #.us smtp8:ref.tfs.com # # joerg@freebsd.org .de smtp8:mail-relay.de.freebsd.org .leo.org smtp8:mail-relay.de.freebsd.org .sub.org smtp8:mail-relay.de.freebsd.org # # via ache@freebsd.org .su smtp8:relay1.kiae.su # # peter@freebsd.org .au smtp8:mail.au.freebsd.org .dialix.com smtp8:mail.au.freebsd.org # # garrett@freebsd.org .edu smtp8:halloran-eldar.lcs.mit.edu # # shaun@emma.sea.uct.ac.za /peter #.za smtp8:storm.sea.uct.ac.za .za smtp8:mail-relay.za.freebsd.org .iafrica.com smtp8:mail-relay.za.freebsd.org .sdd.com smtp8:mail-relay.za.freebsd.org # # roberto@freebsd.org /peter .fr smtp8:mail.fr.freebsd.org .fr.net smtp8:mail.fr.freebsd.org .fdn.org smtp8:mail.fr.freebsd.org # # hacks .netcom.com smtp8:netcom.com .sg smtp8:technet.sg .harris.com smtp8:harris.com .rockwell.com smtp8:rockwell.com .tmc.edu smtp8:tmc.edu # # / gpalmer .uk smtp8:ft-mailhost.brunel.ac.uk # # simokawa@sat.t.u-tokyo.ac.jp / asami .jp smtp8:mail-relay.jp.freebsd.org To see who "mail-relay.de.freebsd.org" is (for example), use the "host" command on FreeBSD and other systems. peter@jhome[4:03am]~src-116# host mail-relay.de.freebsd.org mail-relay.de.freebsd.org mail is handled (pri=100) by zit1.zit.th-darmstadt.de mail-relay.de.freebsd.org mail is handled (pri=200) by gilberto.physik.rwth-aachen.de In this case the primary exploder is zit1.zit.th-darmstadt.de with a fallback of gilberto.physik.rwth-aachen.de. In particular, we are looking for more sites in Asia and the South Americas. Cheers, -Peter
