 Posted: Thu Apr 10, 2008 6:44 pm Post subject: procmail, the MATCH variable and newline |
 |
|
Hi,
I have several email addresses, and I sort incoming mail using procmail depending on the X-Mailbox header (which my smtp inserts):
| Code: |
:0
* ^X-Mailbox: phpldapadmin$
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.phpldapadmin/
:0
* ^X-Mailbox: conkeror$
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.conkeror/
:0
* ^X-Mailbox: ot$
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.ot/
...
|
My procmailrc is getting really full, and I have to add a newline everytime I add a new mail address. So I thought, a more generic way would be cool:
| Code: |
:0
* ^X-Mailbox:[ \t]*\/[A-Za-z0-9]*$
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.$MATCH/
|
The problem with this code is, that the MATCH variable includes the $ (newline) at the end. If the header is "X-Mailbox: ot", it results in this mailbox:
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.ot
(without the trailing /), which makes procmail store the mail in mbox format (I wont it in maildir format).
If I remove the $:
| Code: |
:0
* ^X-Mailbox:[ \t]*\/[A-Za-z0-9]*
/var/vpopmail/domains/lonely-star.org/ls/.maildir/.$MATCH/
|
The MATCH variable is always empty, resulting in
/var/vpopmail/domains/lonely-star.org/ls/.maildir/./
Also, not what I want.
Any Ideas on how to do this?
Thanks!

In your matching expression
| Code: |
* ^X-Mailbox:[ \t]*\/[A-Za-z0-9]*
|
replace the trailing "*" with "+". The asterisk qualifier means "zero or more of the preceeding
expression", and procmail, unlike other regex engines, uses the shortest match - in this case
zero. The "+" qualifier OTOH means "one or more".
Please try it - although I have a sneaking suspicion the modification might yield only one letter
in MATCH, in which case you could try something like \/[^ \t]* (or \/[^ \t]+).
HTH. |

Hi,
Thanks for your reply. I do not really understand why, but
* ^X-Mailbox:[ \t]*\/[A-Za-z0-9]+
works ...
Thanks!
