I have just had to fix a debian5 system which suddenly started rejecting correctly addressed emails as '550 relay not permitted.' It turned out that rogue exim4 config files had been injected into the system at /etc/exim4/exim4.conf and /etc/exim4/exim.conf and these were messing up mail routing.
I also found a few strange processes running which were started around the same time as the problem started. Note that you must restore a valid version of ps (see the link) before you use it to look for rogue processes.
I have exim4 smtp server running on Debian. I tend to use only one user account to login. The machine is running multiple websites and I have assigned unique email addresses for each of the websites.
Emails sent to these addresses do not seem to get delivered. Emails sent to the alias that I... (0 Replies)
This seems to be a rather constant question that pops up on a lot of forums but as of yet I have not found a complete solutions on any of the forums so I'm asking everyone who might know about this in an attempt to find a complete solution for this:

EXIM_CONVERT4R4(8) System Manager's Manual EXIM_CONVERT4R4(8)NAME
exim_convert4r4 - Convert Exim configuration from v3 to v4 format
SYNOPSIS
exim_convert4r4
DESCRIPTION
This script is provided to assist in updating Exim configuration files. It reads an Exim 3 configuration file on the standard input, and
writes a modified file on the standard output. It also writes comments about what it has done to the standard error file. It assumes that
the input is a valid Exim 3 configuration file. A typical call to the conversion script might be
exim_convert4r4 < /etc/exim/exim.conf > /etc/exim4/exim4.conf.new
The output file MUST be checked and tested before trying to use it on a live system. The conversion script is just an aid which does a lot
of the "grunt work". It does not guarantee to produce an Exim 4 configuration that behaves exactly the same as the Exim 3 configuration it
reads.
Each option change in the new file is preceded by an identifying comment. In fact, the conversion script tends to make quite a mess of
your configuration, and you should expect to go through it afterwards and tidy it up by hand.
Unless you are running a very straightforward configuration, the automatic conversion is likely to generate a non-optimal configuration.
You should not only check it thoroughly, but also run as many tests as you can, to ensure that it is working as you expect. In particular,
you should test address routing, using -bt and -bv, and the policy controls, using -bh. If possible, you should also do some live tests
(i.e. send and receive some messages) before putting Exim 4 into service.
If you have a very complicated configuration, it is possible that exim_convert4r4 will break it in some situations, which is why thorough
testing is strongly recommended.
BUGS
This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
would be greatly appreciated.
