Procmail rules with regexp

Question

here are my procmail recipes:

:0 * ^Subject: [JIRA] (EDRV-*) *$ .JIRA.edrive/new :0 * ^Subject: [SPAM] *$ .SPAM/new :0 * ^X-Spam-Status: Yes .SPAM/new :0 * .* new 

I want to put my messages with [JIRA] (EDRV-XXX) in the subject into the JIRA/edrive folder of the mailbox and messages marked with [SPAM] in the subject - into the SPAM folder.

But what I am getting now:

procmail: [8652] Sat Aug 27 19:08:19 2016 procmail: Assigning "SHELL=/bin/bash" procmail: No match on "^Subject: [JIRA] (EDRV-*) *$" procmail: No match on "^Subject: [SPAM] *$" procmail: No match on "^X-Spam-Status: Yes" procmail: Match on ".*" procmail: Assigning "LASTFOLDER=new/msg.qVktB" procmail: Opening "new/msg.qVktB" procmail: Acquiring kernel-lock Subject: [JIRA] (EDRV-100) xxxxxxx Folder: new/msg.qVktB><------><------><------><------><------><------> 2795 

Where is a mistake?

Answer 1

This is a very basic regex error. In order to match [ or ( literally, you have to escape them with a backslash.

The same applies to any regex metacharacter - ., *, |, etc.

Also, to match unconditionally, simply don't put any conditions.

I'm guessing you didn't really mean to only allow whitespace after the matches, so I took those out, too. If you wanted to say "anything", that's .* in regex, but there is no point in having a condition whitch matches anything.

:0 * ^Subject: \[JIRA] \(EDRV-.*\) .JIRA.edrive/new :0 * ^Subject: \[SPAM] .SPAM/new :0 * ^X-Spam-Status: Yes .SPAM/new :0 new 

Answer 2

You need to backslash escape regex characters that you want to match as literals.

It looks like you are using your mail is stored in Maildir format. I don't know if you excluded the header or don't have one. This will deliver files to the appropriate mail subdirectories. It includes a log file so you can verify that the messages were correctly processed.

# .procmailrc - procmail configuration file # Variable definitions MAILDIR=$HOME/Maildir/ LOGFILE=$MAILDIR/procmail.log DEFAULT=$MAILDIR

These rules should match the messages and deliver them to the new subfolder of the specified mailbox.

:0 * ^Subject: \[JIRA\] \(EDRV-.*\) .JIRA.edrive/ :0 * ^Subject: \[SPAM\] .SPAM/ :0 * ^X-Spam-Status: Yes .SPAM/ # Anything left goes to inbox
