exim interview questions
Top exim frequently asked interview questions
I am using Exim. I am trying to "send" all emails to a rails controller, but unfortunately I have no experience with Piping emails. Any help with the configuration of Exim is welcome. What i want is that Exim should forward all emails that are going to "bounce", because no such user exists, to the script
Source: (StackOverflow)
From our rails app we send out some system-generated emails with the 'from' address set to noreply@ourdomain.com. If these bounce they get sent back to this address by our mail server. However, what i'd like to do is to not have bounced emails get sent back to noreply@ourdomain.com but to a different address, such as bounced@ourdomain.com.
Is there a header or something i can set in the email that will achieve this, without me having to go and investigate the vagaries of our email server? We send the mails out using exim in case that's relevant.
cheers, max

This may be a ridiculous question, but it's been bothering me for a while.
I have a mail forwarder piped to a PHP script, it receives perfectly, however I have the following error mailed back to me instantly:
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
pipe to |/home/[webroot]/public_html/external/mobile/email.php
generated by mobile@[mydomain]
The following text was generated during the delivery attempt:
X-Powered-By: PHP/5.2.13
Content-type: text/html
As you can see, Exim thinks the header response an error from the script I have. The script can receive the Email perfectly from php://stdin but Exim is quick-replying with the error.
Plus,
- It's running from console, not Apache so HTAccess or configuring Apache most likely would do nothing.
- I can not find any solution, or anyone with the same problem.
So my question is: How to I get rid of those two headers?
Thanks,
~Jonny

<?php

$email .= fread($fd, 1024);
}
fclose($fd);
$dat = fopen(dirname(__FILE__).'/test.txt', 'w');
fwrite($dat, $email);
fclose($dat);

I am looking to set up a mail relay so that any mail sent to for example
@example.com
gets parsed be a PHP script.
I know to do this for indervidual address I could do some thing like
(from the following web site http://evolt.org/incoming_mail_and_php)
Con figure an Aliases such as
script: |/our/script.php
then any emails sent to script@example.com will be passed to the script given..
but how can I make it that every email to @example.com is passed to the script?
thank you

I'm new to Exim and I'm using it as a smarthost (to recive emails from users and send it to my ISP).
The system is working ok, but I have some problems with frozen messages. I watch the queue sometimes and there are some frozen messages without sender, so Exim cannot send them, because if there isn't sender it can't authenticate with the ISP.
Where can I start to debug this?
Thanks a millon.

I'd say it's quite a simple question but I'm stuck with it:
I need to communicate with external program (specifically, Exim) run with some debug options. As I run it from linux shell, it goes like this: run exim -bh 11.22.33.44, then read its output (both STDOUT and STDERR), the type in some line from SMTP dialog, then read Exim output again, type another SMTP line and so on. And it's nicely works while I'm on bash shell, but as I run it from PHP script it stuck in STDIN read loop.
I use proc-open:
$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pipe", 'w'),
2 => array("pipe", 'w')
);
$process=proc_open('/usr/sbin/exim -bh 11.22.33.44', $descriptorspec, $pipes, NULL, NULL);
if (is_resource($process)) {
stream_set_blocking($pipes[1], 1);
stream_set_blocking($pipes[2], 1);
while(!feof($pipes[2])) {
$txt2 = fgets($pipes[2]);
}
while(!feof($pipes[1])) {
$txt2 = fgets($pipes[1]);
}
fwrite($pipes[0], 'HELO testhost');
...
}
Looks simple, but as it goes to the end of first STDERR, it stuck.
Tried both blocking and unblocking mode, tried to swap reading from STDERR and STDIN - no luck so far.
Please point me the right way to do that!

Currently I am filtering incoming mails by a .forward in the following way:
if $header_to: matches "(office|info)@domain.com" then
save Maildir/.office/
endif
if $header_to: matches "whatever@domain.com" then
save Maildir/.whatever/
endif
So I have a mail account, which receives mails for different addresses. Basically I want them to land in different subdirs based on the address the mail was sent to.
This works for mails where the recipient is in the to-header, but does not work if the recipient was in the bcc.
When a mail is received which was sent with the bcc-header, only the envelope-to-header matches the real address the mail is delivered to and it is mentioned in a Received-header
Envelope-to: office@domain.com
Received: from mail.other.domain ([1.1.1.1])
by mail.domain.com with esmtps (TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32)
(Exim 4.71)
(envelope-from <sender@other.domain>)
id 1RO5xc-0001TF-Qj
for office@domain.com; Wed, 09 Nov 2011 12:04:57 +0100
...
To: can_be_anything@whatever.com
I already tried:
if $header_envelope-to: matches ...
but this does not work, mails are not filtered at all even when sent with To-header (looks like the Envelope-To-header is not available in forward-files). Should I try to parse the (multiple) Received-headers?
How can I move mails into a subdir of the recipient based on the real recipient address?

What I want to do is pretty simple - I want the output from cron on an EC2 instance to go to an external e-mail address. I've clearly done some wrong things, though, and am confused.
I've configured exim4 to use gmail as a smart host, but somehow I've managed to do something to get the e-mails from the cron daemon to come as From: Cron Daemon <email address from /etc/exim4/passwd.client>. Why has cron decided to run as me?
I have
root: external@email.com
user-account: external@email.com
in /etc/aliases. However, I get emails sent to that say
Delivery to the following recipient failed permanently:
root@domu-____.compute-1.internal
Why is exim4 trying to reach root by such a weird-looking e-mail address? I could theoretically add domu-(redacted).compute-1.internal as a local domain in the exim4 config, but these are dynamically provisioned instances, and that would be a real pain, and I also don't know where in the world that domain is coming from - hostname -f gives ip-11-11-11-11.ec2.internal. What have I done to make cron do something other than just send to root@localhost (which given my config would work fine)?

Debian Squeeze/Exim 4.72: ACL
I have the more or less standard exim acl for rejecting emails based on mime attachments with some common compressed file extensions added in (.zip/.rar etc.)
deny set acl_m1 = ${extract{-1}{.}{${lc:$mime_filename}}}
message = This message contains a prohibited file extension ($acl_m1)
log_message = REJECTED ATTACHMENT ($acl_m1)
condition = ${if match{$acl_m1}\N^(ade|adp|bas|bat|chm|cmd|com|cpl|crt|eml|enc|exe|hlp|hta|inf|ins|isp|js|jse|mdb|lnk|mde|msc|msi|msp|mst|pcd|pif|rar|reg|scr|sct|shs|url|vbs|vbe|wsf|wsh|wsc|zip)$\N}{1}{0}}
Q: How would I use a "Whitelist" to allow specific users to receive emails containing attachments of a certain type (e.g. .zip)?
Thx

I have dedicated server with many domains on it.
I want to catch all emails from specific addresses for any domain that means accepting all emails from xxx@example.com and forward it to a specific address.
I used, Exim on my server and cpanel.
I don't want a method to accept and forward on one account!

I can't find exim on the latest cygwin installation (1.7.29). Was it removed? How can I install it in such a case?

My Exim mail queue was full of spam so I ran a custom grep command to search out spooled messages that contained the spam terms. Problem is, I didn't know that Exim breaks messages up into multiple files (one for header information, one for data, etc.) so my grep command deleted the data files while leaving the header files.
Does anyone know of a way I can easily find and delete messages in the queue that have a header file but no data file? Or another way to fix it?
