[exim] Run a Program from within Exim
Hi All,
Sorry if I am repeating something already asked. I searched the
archive before sending this question and found only one thread that
appears to be related, but does not seem to work.
The short of the story is that I need exim to execute another program
upon the delivery of an email and send that program the following
string:
"/var/spool/maildirs/${substr_0_10:$tod_log}/${domain}/${local_part}/Maildir/new"
For example, I tried adding a condition to my local_delivery transport
that looked like this:
condition = {run echo
"/var/spool/maildirs/${substr_0_10:$tod_log}/${domain}/${local_part}/Maildir"
>> /dev/shm/temp.file}{0}{1}
In this example I am simply trying to echo that string to a file in
/dev/shm. I do not get an error in my logs, but I also do not get
this file.
Any advice is much appreciated.
Thanks!

The ">>" is a shell operator. ${run doesn't use shell by default.
An example from my config:
LIM = 100
PERIOD = 1h
WARNTO = ab...@example.com
DIR = /var/spool/exim
EXIMBINARY = /usr/local/sbin/exim
SHELL = /bin/sh
...
acl_check_rcpt:
...
accept authenticated = *
set acl_m_user = ${sg{$authenticated_id}{\N\W.*$\N}{}}
condition = ${if exists{DIR/blocked_users}}
condition = ${if eq{${lookup{$acl_m_user}lsearch\
{DIR/blocked_users}{1}{0}}}{1}}
control = freeze/no_tell
add_header = X-Authenticated-As: $acl_m_user
accept authenticated = *
!verify = recipient/defer_ok/callout=10s,defer_ok,use_sender
ratelimit = LIM / PERIOD / per_rcpt / user-$acl_m_user
continue = ${run{SHELL -c "echo $acl_m_user >>DIR/blocked_users; \
\N{\N echo Subject: user $acl_m_user blocked; echo; echo because \
has sent mail to more than LIM invalid recipients during PERIOD.; \
\N}\N | EXIMBINARY WARNTO"}}
control = freeze/no_tell
add_header = X-Authenticated-As: $acl_m_user

What do you mean by "send"? Give as an argument? Write to its stdin?

RTFM:
1. The syntax is
${run{ }{}{}}
not
{run ...}
2. "As in other command executions from Exim, a shell is not used by
default. If you want a shell, you must explicitly code it. "
As you use redirection in your test, you need to use a shell there.
3. You have to give the full path to the executable you want to run.
(Unfortunately, this is not documented in the spec of the ${run...}
expansion item. Should probably be added.)
So the expansion string would look like this:
${run {/bin/sh -c "echo
/var/spool/maildirs/${substr_0_10:$tod_log/${domain}/${local_part}/Maildir
>> /dev/shm/temp.file"}{0}{1}}
You really have to take care here that nobody can do shell injection
(e.g. by using ';' or other special shell chars in the local part). This
only applies when using a shell, so you should probably avoid that. Just
use a little script, that logs what your program would get, e.g.
#/bin/sh
echo $1 >> /tmp/bla.log
and use that instead of your real program.

Errors are hidden here. Look into $runrc to see what went wrong.

[exim] Problem with .forward
Hello.
I'm french user of exim4 and i apologize for my bad English.
I configured exim4 with clamav and spamassassin on Debian.
Clamav :
deny
malware = *
message = This message was detected as possible malware ($malware_name).
And Spamassassin :
accept
condition = ${if >={$message_size}{500k}{yes}{no}}
warn
spam = nobody:true
message = X-Spam_score: $spam_score\n\
X-Spam_score_int: $spam_score_int\n\
X-Spam_bar: $spam_bar\n\
X-Spam_report: $spam_report
deny
message = This message scored $spam_score spam points.
spam = nobody:true
condition = ${if >{$spam_score_int}{120}{1}{0}}
I'm doing tests with viruses, and spam testing and everything works well.
The problem is with the .forward
# Exim filter
if error_message then
finish
endif
if $h_X-Spam_score_int is above 50 then
save Maildir/.junkmail/
finish
endif
finish
The problem is with the .forward. When I receive a local mail or mail with
attachments, I get a *Mail Delivery System,
*
An error has been found in your .forward file.
If someone knows the solution to this problem

[exim] Exim 4.71 on netBSD pthreads
Dear all, i'm fiddeling some time here with an update to Exim 4.71 on NetBSD but can't get it running as the running process complains: 14512 LOG: MAIN 14512 exim 4.71 daemon started: pid=14512, no queue runs, listening for SMTP on [w.x.y.z]:26 [127.0.0.1]:26 [127.0.0.1]:10026 _res is not supported for multi-threaded programs. this seems not new and so i found and followed this thread: http://mail-index.netbsd.org/pkgsrc-users/2009/11/18/msg011153.html and tried to remove all parts which (i think of) pulling out pthreads out of the exim build, but this brought no solution for me and btw i rely on things like mysql and openssl here. This is my last working exim version on NetBSD (exim 4.69): # ldd /usr/sbin/exim /usr/sbin/exim: -lc.12 => /usr/lib/libc.so.12 -lcrypt.0 => /usr/lib/libcrypt.so.0 -lm.0 => /usr/lib/libm387.so.0 -lm.0 => /usr/lib/libm.so.0 -lcrypto.4 => /usr/lib/libcrypto.so.4 -lssl.6 => /usr/lib/libssl.so.6 -lz.1 => /usr/pkg/lib/libz.so.1 -lmysqlclient.15 => /usr/pkg/lib/libmysqlclient.so.15 -lresolv.1 => /usr/lib/libresolv.so.1 -lsasl2.2 => /usr/pkg/lib/libsasl2.so.2 And this is what i get compiled with 4.71: # ldd build-NetBSD-i386/exim build-NetBSD-i386/exim: -lc.12 => /usr/lib/libc.so.12 -lcrypt.0 => /usr/lib/libcrypt.so.0 -lm.0 => /usr/lib/libm387.so.0 -lm.0 => /usr/lib/libm.so.0 -lcrypto.4 => /usr/lib/libcrypto.so.4 -lssl.6 => /usr/lib/libssl.so.6 -lz.1 => /usr/pkg/lib/libz.so.1 -lmysqlclient.15 => /usr/pkg/lib/libmysqlclient.so.15 -lpthread.0 => /usr/lib/libpthread.so.0 -lcrypto.0.9.8 => /usr/pkg/lib/libcrypto.so.0.9.8 -lssl.0.9.8 => /usr/pkg/lib/libssl.so.0.9.8 -lresolv.1 => /usr/lib/libresolv.so.1 -lsasl2.2 => /usr/pkg/lib/libsasl2.so.2 -lpcre.0 => /usr/pkg/lib/libpcre.so.0 As the machine is not used for exim alone it would be very nice to find any kind of solution here - i'm happy about any hint or tip here... many many thanks in advance. cheers, Niels. -- --- Niels Dettenbach --- Syndicat IT&Internet http://www.syndicat.com T.-Muentzer.-Str. 2, 37308 Heilbad Heiligenstadt - DE --- Kryptoinfo: PGP public key ID 651CA20D Fingerprint: 55E0 4DCD B04C 4A49 1586 88AE 54DC 4465 651C A20D https://syndicat.com/pub_key.asc --- -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
Re: [exim] Problem with .forward
I think that in case the value of $h_X-Spam_score_int is undefined, the
filter can not work.
I did a test with this rule has proved correct
# Exim filter
if 40 is above 70
then
save Maildir/.junkmail/
finish
endif
So if a mail came from the local area there is no value in the variable.
It should therefore that I can write a rule saying that if the header exists
X-Spam_score_int, then I apply the rules

Since the last time the NetBSD incompatible changes to _res behaviour changes came up, I've bought a new laptop and have a VM system installed on it. I'll set up a NetBSD VM and look into what are the minimal code changes needed to support NetBSD without turning the source code into spaghetti.

Re: [exim] Exim 4.71 on netBSD pthreads
Dear Phil, i've got it running for now with some ugly hacks here (i.e. i've deleted all sqlite stuff and tricked with other libs) - so i'm really happy if someone brings exim back to "compatible" with NetBSD again as i like EXIM like NetBSD (it's a really nice couple...). If you need active devel- or beta-tester(s) for your code for NetBSD - just contact me. In case you prefer a small NetBSD VM for testing purposes this would be possible too.
