[Phamm] Automatic creation of maildirs when using maildrop.

[Jorge Armando Medina]

Hi list.

After some time I finished the new revision of my howto,
Ok, this are the instruction for automatic creation of maildirs when we are
using maildrop as MDA.

First of all, we will use the virtual_mailbox_base = /home/vmail/domains
parameter as our filtering base.

Maildrop can use the /etc/maildroprc as the default and global filtering rules 
file and per user files: .mailfilter we will use the last because it wont 
affect our system when we upgrade maildrop.

As I said we will use /home/vmail/domains as our base, then we will create 
there our .mailfilter file:

# touch /home/vmail/domains/.mailfilter
# chown vmail:vmail /home/vmail/domains/.mailfilter
# chmod 600 /home/vmail/domains/.mailfilter

NOTE: Don't forget to set those permisions.

Maildrop can use enviroment variables to make references to arguments and 
directories:

Wi will use this global variables:

HOME=/home/vmail/domains
DEFAULT=domain.tld/username/
LOGNAME=username at domain.tld

Now, let's fill the .mailfilter file, the example is attached.

It is important to se the welcome message in phamm,

With this setup, whenever a new mail comes, maildrop will log something like 
this to /home/vmail/maildrop.log

If we want to use per user filtering, we need to create a .mailfilter file in 
the user mailbox directory, for example:

# cat /home/vmail/domains/tuxjm.net/jmedina/.mailfilter
log "Processing per user filters for: $LOGNAME"
if (/^X-Spam-Flag: YES/)
{
log "Moving Spamassassin tagged mails to the SPAM Folder"
log "into $LOGNAME Mailbox."
  exception {
    to $DEFAULT.SPAM/
  }
}

You can comment the "log" parts, I configure them for better debuging.

For example you can see something in the maildrop.log file:

====  BEGIN maildrop processing for jmedina at tuxjm.net ===
Including /home/vmail/domains/tuxjm.net/jmedina/.mailfilter
Processing per user filters for: jmedina at tuxjm.net
Moving Spamassassin tagged mails to the SPAM Folder
into jmedina at tuxjm.net Mailbox.

Subj: *****SPAM***** Do you viagra?
File: tuxjm.net/jmedina/.SPAM/

Well you can do a lot of practical things with maildrop, this is only one 
example, for more info you can read this pages

I hope this text is easy to understand, if not someone can rewrite it with a 
bette english? :D

Best regards.
