They've been around for decades, with their functionality identical to the same functionality in Qmail, which has the same exact concept. The fact that they can be created at will – we'll they're just files, that's all. pgpJu3t1YN79F.pgp Description: PGP signature -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

I have just discovered, that if user "www-data" touch the file
"~/.courier-foo" courier accept it and does not complain about a from
file owner!
I allowed my PHP scripts to create/modify/delete files in the user homes
but only if they do not exist.
It seems, this way the problem is solved!
Now I have only to solv the problems with aliasses, because I do not
like to expose my "local account" to spammers.
Mean, my account is I can create any attachments to
it, but it will not work for my alias .
It would be very handy, if courier support it.
Thanks for your time

I am user "michelle.konzack" on the system and my account has the files ~/.courier ~/.courier-default ~/.courier-aliasses (which is symlinked into /etc/courier/aliasses/ ) the "~/.courier-default" point to a special filter which can sort out which mails I want to see and are sorted into mailfolder /dev/null ;-) However, I have installed a traffic counter on this filter to get an idea, how much spam I receive over the last 9y since I have installed the domain/server, this mean if I allow all users to do this, my mailserver would accept arround 300-500 GByte of additional spam. Removing "~/.courier-default" and use instead "~/.courier-" would be a better solution but require root rights (sudo?) to be installed from a webinterface...

It seems (on Debian/Wheeze) makealiasses do not like to run from scripts and need a terminal. I have to check this again, but I am currently very bussy with my new Bio Farm in Estonia ;-) since I get in some month 1500 apple/cherry trees.
