No, that courier accept in the USER_HOME a file,
which is not owned by the USER.

Already discovered...  ;-)

I was not aware, that courier allow this.


What, the existence of the .courier files themselves? 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.

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...

Thanks for your time

I have gotten strange errors while running makealiasses from  a  script.
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.

Over the winter I have nothing to do and can go back deeper into IT.

Would it be sufficient to do something with the .courier-aliases?  Tell
your users to create something like:

.courier-forwardtodevnull

containing:

| cat > /dev/null

or whatever you want.  I've occasionally done this myself for mail I don't
want to receive.

I would probably do it through entries in the database db. But if you
already have "something" editing the aliases file, why not have it run
makealiases, too?

Best thing is to have an utility synthesize a throw-away address and insert it
directly in the users database, possibly along with some annotation.  Rather
than develop that, I subscribed to trashmail.com.  The feature I had little
desire to develop and maintain is the firefox addon that implements the "paste
disposable address" command.  It is too convenient not to use it.

I asked them about getting their functionality on my server, and Stephen 
replied:

Using its own server is better to have the full control. The only solution
I see for that would be to install a full clone of TrashMail.net with its
complete API. I was thinking already about that to propose this as
business solution. [...]

[courier-users] Throw-Away EMails

[Michelle Konzack]

Hello,

what is the easiest way to allow users to creat throw-away emails?

I do this somehow over aliases, but when I  change/delete  one,  I  have
always to run makealiases.  I do not really like  the  idea,  to  run  a
bashscript from cron all 5 min which check the users aliasses files  and
execute makealiasses if a changement has been detected.

Thanks
