I do not know if others have experienced this but the quality of copier/printer paper now available to us exhibits noticeably inferior stability when wetted from paper of the same weight from the same brand-name supplier obtained as recently as four years ago. I can attest to that because I have compared the two. Increasing the paper weight improves wetted stability only marginally and certainly not the the level exhibited in the older paper stock. And this is so-called 'premium' stuff I am writing about. I suspect the increasing use of recycled, and therefore shortened fibre, in production of modern papers has something to do with this. -- *** E-Mail is NOT a SECURE channel *** James B.

It is supposed to turn itself on again if the printer asks for power, it doesn't. I need to pull the plug, reinsert is and switch on the printer within 5 sec. :-( > >> Thanks for your knowledge and experience. > FWIW. > > Bonno Bloksma > In the comments about the Photo Smart 7520 on Amazon I read about people (or maybe it was just one guy) who claimed he needed to repeated plug and unplug the power cord to get it to work. What you describe is probably that problem. Another guy on Amazon said that his printer mysteriously turned itself off one day. Thanks for the info! And the great clarification. I certainly don't want to buy a printer that's going to throw problems at me all the time. Sometimes I feel like the public has been turned into a bunch of beta testers for some of this new technology.

Amavisd-new delivers spam emails
by Jussi Hirvi 11 Sep '14

11 Sep '14

I recently noticed that my email server now delivers spam to final recipients even though the spam score is more than the $sa_kill_level_deflt. A probable reason is that some amavisd update has introduced new configuration variables, which I have not defined in my configuration, and the default value of some such variable causes this unwanted behavior. I tried to go through documentation, but did not find the reason. Has anybody else had the same problem? # amavisd -V amavisd-new-2.8.0 (20120630) - Jussi
