Well to use other SMTP relay than the one from the used ISP is not allways possible, and should be prevented anyway. nearly 100% of the spam is caused by direct senders, very seldom they use the ISP's Relay. so lets close that big spamfriendly hole.

Geneva-Romandie Beer Event again
by Gregoire Huet 13 Feb '07

13 Feb '07

Hello everybody ! A new Geneva Beer Event is under preparation ! Attendees can still for about 1 week give their date preference on : http://www.doodle.ch/dpK24dP43J2d The place would be the same as the last time : the Moloko bar, inside L'Usine. I guess we should organize a vote, once the date will be fixed, to know how many people would get dinner. Thanks Greg

cacti multiple rra settings
by Philippe Strauss 06 Feb '07

06 Feb '07

Hello swinogers, does anyone know if there is a way, with cacti, to use different RRA settings for different RRD archive? I've only found one global "template" for the whole cacti installation, and sometimes I would like to setup some RRD to keep one month of 5minutes sampled data, but it doesnt seem to be possible to have differents RRA templates. regards. -- Philippe Strauss av. de Beaulieu 25 1004 Lausanne http://philou.ch
