procmail error

My procmailrc:

MAILDIR=/var/spool/mail
LOGFILE=/var/log/procmail
SHELL=/bin/bash
VERBOSE=on

:0 B
* (filename|name)=.*\.(bat|cmd|com|dll|exe|...|vbs)
dev/null

:O H
* ^(From|X-from|Sender|X-sender|Reply-To|Received|Reply-To):.*\
(abcdef\.com\.br|\
almg\.gov\.br|\
@com\.br|\
...
usa\.com)
/dev/null

:0:
${MAILDIR}

and I'm getting some weird error, as for the double back slash "/var/spool/mail//procmail" below:

procmail: Locking "/var/spool/mail.lock"
procmail: Error while writing to "/var/spool/_A9E.vPiB8.int.efoa.br"
procmail: Lock failure on "/var/spool/mail.lock"
procmail: Error while writing to "/var/spool/mail/_A9E,vPiB8.int.efoa.br"
procmail: Couldn't create or rename temp file "/var/spool/mail//procmail"

I would apreciate any help.
Thanks in advance.
