Email Stops Working w/ Procmail (Postfix)
 

I have a full functioning email server running Postfix, Spamassassin, and Dovecot on my Linux server. Now I am trying to filter email from Spamassasin headers using procmail however when I add this:

to my /etc/postfix/main.cf, any email that normally gets delivered to /home/user_name/Maildir from Postfix now gets queued in /var/mail/user_name.

I don't understand why this small change is causing Postfix not to deliver incoming messages to my Maildir and rather to /var/mail/user_name.

I am posting my main.cf if anyone can please tell me what I am doing wrong. When I disable (comment) this option from my main.cf. Incoming email is no problem.

main.cf

carlos@swordfish:/var/mail$ cat /etc/postfix/main.cf
# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Linux)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = swordfish.carlwill.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = carlwill.com
mydestination = carlwill.com, swordfish.carlwill.com, localhost.carlwill.com, localhost
relayhost =
mynetworks = 192.168.1.0/24, 192.168.2.0/24, 127.0.0.0/8
#mailbox_command = /usr/bin/procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
relay_domains = carlwill.com
home_mailbox = Maildir/

Because Postfix isn't delivering the messages any more procmail is.

I don't know a heap about procmail (I use maildrop), but I would guess you need a suitably configured .procmailrc in the user's home direcory. The Postfix site has info on using procmail (most of it in the negative as I recall)

OK - before I created the .procmailrc file in the home dir, I wanted to make sure I was not going to far and breaking stuff and noticed a huge change after step one. I will read Postfix info and see what the best route would be...
