Exim 4.94 update causes email temporary rejects

Yes looks like they are working on it a few Taint Bugs in there. Looks like they have a fix but not sure if its Released.

I've downgraded to Exim 4.93 and exim_conf 4.5.22 to resolve the issue temporarily.

/usr/local/directadmin/custombuild/custom_versions.txt and added:
exim_conf_45:4.5.22:
exim:4.93:

After that i rebuilded exim, that solved the issue for now and my mail queue is running perfectly again.

All of these were backported to 4.94 on DA fileservers when they got fixed (the same day DA included 4.94 in versions.txt). So, they're not a problem there :) It's likely some post/pre custom configs, or not latest versions of exim/eximconf.

exim=yes

clamav=no
mailman=no

dovecot=yes

I don't have any custom configurations.

The exim.conf diff from the da server (http://files.directadmin.com/services/exim.conf) compared to the /etc/ one:

< file = /var/spool/virtual/${domain}/${local_part}
---
> directory = /home/${lookup{$domain}lsearch*{/etc/virtual/domainowners}{$value}}/imap/${domain}/${local_part}/Maildir
> maildir_format

Which, as far as I understand is patched by ./build exim_conf


Am I missing something?

Ok, that makes sense to result in failure then - so why this:

Even though I explicitly specify 4.5 and it is in versions.txt:

Please let me know the output of:
Code: 
cd /usr/local/directadmin/custombuild
./build version
grep ^exim options.conf

I guess you're using EOL CustomBuild 1.X.
 
Was this eventually solved? We get tons of

Anybody here got some suggestions?
 
I removed exim.conf and did a ./build exim && ./build exim_conf several times. I've got

```
exim=yes
eximconf=yes
eximconf_release=4.5
```

in my options.conf
 
Have you checked your Custombuild version? The last solution/problem was around using Custombuild 1.x.

If you type ./build on top it should say like Version: 2.0.0 (rev: 2513)
 
I've switched to version 2 (was using 1) after reading this post, but that didn't seem to change anything intuit part. It does build 4.94, but the config file used is invalid. It contains that if exists-line and that triggers those errors in maillog in receiving.
 
So when you switched fro CB 1 > 2 did you do all of this?

CustomBuild 2.0 FAQ (DirectAdmin 1.46 or later is recommended)

CustomBuild 2.0 plugin to control CustomBuild from DirectAdmin UI: http://forum.directadmin.com/showthread.php?t=48989 1. What is custombuild? Custombuild is a tool, which can install/update: Apache AWstats Autoconf Automake ClamAV cURL Dovecot Exim configuration files FreeType GD htscanner...
forum.directadmin.com forum.directadmin.com

2. How to upgrade custombuild to 2.0?
The best way to do that is a complete reinstallation of CustomBuild, because of changes in configuration files, options.conf etc.
Please note that you need DirectAdmin version 1.46 at least to run CustomBuild 2.0.

IMPORTANT: It's recommended to execute pre-installation commands again before the upgrade: http://help.directadmin.com/item.php?id=354.

Code:
cd /usr/local/directadmin
mv custombuild custombuild_1.x
wget -O custombuild.tar.gz http://files.directadmin.com/services/custombuild/2.0/custombuild.tar.gz
tar xvzf custombuild.tar.gz
cd custombuild
./build update_da

Please check your options.conf file, set the settings you would like to have. The following steps are needed after upgrade of the CustomBuild script, if you would like to use apache:
Code:
./build apache <<< Your webserver here.
./build php n
./build rewrite_confs

However, if you want to rebuild everything:
Code:
./build all d
