For a single address, you could put this somewhere ahead of the recipe:

Matching literal dot in To

I use the following to match a literal dot in the To field, the dot 
(period) has to occur prior to the  <at>  character.  The recipe is:

"^To:.*\..* <at> .*"

For some reason, the recipe matches some (but not all, I have not found 
a pattern yet) addressees in the To field where there is no dot in the 
To address prior to the  <at>  sign.  Logging shows the match occurring, but 
of course it does not give a reason why.

Any ideas on how to trouble shoot further?

Regards and thanks in advance for any help.

Time-based filtering in Procmail

Wondering if anyone has done anything with procmail and time based filtering.

For example, doing something different if a message arrive between midnight and 6am.

It’s just some regex and the top Received line, but I’d rather not duplicate work.

Anyone?

Limit user actions in .procmailrc

I'm updating a fairly old and very idiosyncratic mail system, and one
of the features of this system is that only explicitly listed users
can call external commands from within a .procmailrc.  I think this is
actually accomplished by having both a "regular" procmail for the
listed users, but a "hobbled" procmail that was locally compiled to
disallow such things, but in any case, I'm wondering what options I
have to recreate similar functionality?

Is there something equivalent to sendmail's smrsh functionality for
procmail?

I've looked briefly at jailkit and jk_procmailwrapper, but it has
pretty limited documentation and makes it look like users already need
to live in jailed shells as well as requiring a non-standard mailbox
location, so it's definitely not my first choice.

Another idea that occurred to me would be to prevent .procmailrc
execution by setting DROPPRIVS equal to "no" in the system
/etc/procmailrc unless the LOGNAME value appears in a file that listed
allowed users?  Does this even seem do-able?  I don't know if this
would be an acceptable solution for us, but I won't even bother trying
if it's not possible (or just a plain "Bad Idea").

Somewhat related to that, is it possible to set DROPPRIVS to yes, and
then change it to no later in /etc/procmailrc?  I'm thinking of a
situation where the system procmailrc might look for a user with a
vacation message setup, drop to being them to run vacation, and then
set DROPPRIVS=no to prevent any .procmail from being executed.

Thanks for any insight you might have to offer

Stripping extra stuff from text

I have the following which generates a 140 character blog for sending me an SMS alert:

MSGTEXT=`/usr/local/bin/formail -I ""`
SMSTEXT=`echo $MSGTEXT | lynx --dump --dont_wrap_pre -stdin | tr '\n' ' ' | /usr/bin/cut -c1-140`

:0c
      | (formail -brt -I"Subject: ${CLEANFROM}" \
        -I"To: ${MOBILE}" \
        -I"From: lbuter <at> kreme.com"; \
        echo $SMSTEXT) | $SENDMAIL -t

This works fine, but I end up with text like:

SMS:    This is the body of the email. It should be more than 140 characters to    = test if the cut pipe is working and
if this message will be 

As you can see, I have leading spaces, and an extraneous =, but if I remove lynx from the chain, I will get HTML
crap in the message on those messages.

Is there a simple way to remove any extra space AND encoding cruft, or do I just need to stack up some tr or sed
pipes?

strange error in my procmailrc

when the procmailrc hands off mail for my personal account it logs an error:

User me <at> mail.covisp.net has a .procmailrc, processing...
date: illegal time format
usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... 
            [-f fmt date | [[[[[cc]yy]mm]dd]HH]MM[.ss]] [+format]

None of the other accounts with .procmailrcs log this error, but when I look in my .procmailrc for date:

$ grep date /home/me/.procmailrc 
DATE=`date '+%d-%b-%Y'`
MDATE=`date '+%Y-%m'`
YDATE=`date '%Y'`
LONGDATE=`date "+%y-%b-%d %I:%M:%S %z"`
LOG="`date`${NL}Checking Spam Status... "
  LOG="done. `date`$NL"
  LOG="Delivered `date`$NL"
LOG="Delivered `date`$NL”

None of these seem like they should be throwing any sort of error. They all execute fine from the command line
and date is in /bin/ so I don’t think it could be a path problem. Also, there are not errors logged to my
procmailk log file, only to the global log file/

Any dangers with this recipe?


I know I'm probably being petty and unreasonable but there we are.  A 
couple of events have really annoyed me.

Firstly, I politely asked a company to stop sending emails to an address. 
They said the couldn't and I think they quoted the data protection act. 
They said I had to do it myself on their website.  Hmmm, was that true?

The second event was a company that sent me several emails on the same day 
to an address that only appears as a contact address on my website.  I 
wondered if I could persuade them to stop.  As I don't want the website 
email address to be repeated here, I've used xxxx <at> example.com in the 
recipe below.

I've attempted to target specific people at the company concerned to annoy 
them with their own email spew. devnull <at> clifford.ac is rejected by 
sendmail so hopefully no mail loop.  And I tagged my gmail address I use 
for testing onto the the list of recipients so I could see what I was 
sending out.

Any problems/dangers?

:0
* ^to:.*xxx <at> example\.com
* ^from:.*michael <at> smmexevent\.com

help with a recipe

I have a recipe to sack all maildaemon mails to a file:

  :0 H
  * ^FROM_DAEMON|^FROM_MAILER|^From:.*(MAILER-DAEMON|spam_master|postmaster|ait-admin|Mail 
Delivery|bounce <at> )|^To:.*-request
  * ^Subject:.*(Error Condition|DELIVERY FAILURE|Delivery Status Notification|Delivery
delayed|Returned mail|Undeliverable|failure 
notice|Warning: could not send message)
  Mailerror

(Note /* ^FROM_DAEMON/ and /* ^Subject/ lines may be wrapped in this mail; 
the 4th line is "Mailerror".)

However it misses mail bounces like:

  From: postmaster <at> xxx.xxxxxxx.xx
  To: xxxxxxx-request <at> xxxxxxxxxx.xxx
  Subject: Undeliverable: xxxxxxxxxx

I could not find but does my construct have a problem?

procmailrc to match body

I wrote a set of procmailrc recipes to "quarantine" certain category of
incoming mails to my site. It works with 3 simple steps: when a mail meets
certain criteria, it triggers a "quarantine" process by (1) holding the mail while send a confirmation mail to the sender; (2) when the confirmation mail is replied by the sender, the mail gets delivered normally; (3) when the confirmation mail is bounced, the mail is trashed.

So far everything worked well.

Lately I noticed a minor problem with my recipes to recognize certain bounced mails (a small proportion of all bounced).

My recipe to catch bounces is like:

:0
* ^FROM_DAEMON|^FROM_MAILER
* ^To:.*(mailmaster <at> xxxxxx.xxx)
{
   :0 B
   * ^.*Verify the mail you sent: \/[0-9a-zA-Z\.]+
   {
     MATCHED="$MATCH"

     :0 fw
     | cat "$MAILDIR/QUARRENTEEN/$MATCHED" >> $SPAM;

     :0 a
     | echo 'bounced, go to spam' > "$MAILDIR/QUARRENTEEN/$MATCHED"
   }

   :0 e
   /var/mail/Mail-error
}

which works well for most except one type of bounces from certain mail daemon, with multi-parts:

----------start quote---------------------
From: Mail Delivery Subsystem <MAILER-DAEMON <at> xxxxxx.xxx>
Subject: Returned mail: see transcript for details

(omitted)

   [ Part 2: "Delivery Status" ]

(omitted)

   [ Part 3: "Included Message" ]

 Date: Wed, 28 Jan 2015 14:05:32 -0600
 From: mailmaster <at> xxxxxxxx.xxx
 To: xxxxxxxxxxxxx <at> xxxxxxxxxxxxxxx.us
 Subject: Verify the mail you sent: 20150128.140532KAMGTNXTV

 This mail hub is withholding a mail just received from you:
  - sent to <xxxxxxxx <at> xxxxxxxxxx.xxx>
  - with the Subject: "Find lost or stolen items from your iPhone."
 
 This is to verify that the mail from your mailbox is not a spam.
 Please confirm by replying this mail (no need to write anything;
 only be sure to include this mail in the reply, and leave the Subject
 line and mail body as they are):
 
   Verify the mail you sent: 20150128.140532KAMGTNXTV
 
 Your mail will be automatically delivered when the system receives
 this confirmation from you.
 
 Thank you.
----------------end quote-----------------------

which fell into "Mail-error". It appears the body match failed. Any advice how the recipe should be modified in order to catch this?

Thanks, joe

procmail local delivery and aliases expansion

Hi,

I am using esmtp which in turn uses "procmail -d %T" for local
mail delivery - and would prefer to avoid installing any of the
big sendmail-like packages.

Problem is, procmail does not expand aliases when used like this 
so mail from daemons to root etc ends up in the wrong places.

Coding the alias expansion myself should not be too difficult but
perhaps it has been done before?

Richard
