Sven, your recommendation much appreciated, but didn't altogether
clear up the situation.

I took a look at /usr/share/doc/exim4/README.Debian.gz and found that to
use a macro to change a default configuration value I need to define the
new value in a local configuration file. I have a non-split
configuration, and so it seems I must create a
/etc/exim4/exim4.conf.localmacros file.

The document says that if present this file is read before the
exim4.conf.template file. I don't understand. Wouldn't reading the
template file subsequently to it just overwrite my custom value with
the default value?

In this localmacros file it seems that I simply need the line
MESSAGE_SIZE_LIMIT=200MB to redefine maximum message size from the
default 50 MB to 200MB. I'm unsure of the syntax here. Is "MB"
acceptable? Need it be separated from the number by a space? The
document seems to say that for answers to such questions I should read
the Exim Specification 6.4. It does not tell me where this specification
is to be found.

Another point of confusion is that MESSAGE_SIZE_LIMIT is referred to as
a macro, but in context it seems more just a variable. To set a custom
value, do I have to write an entire macro from scratch, which seems
implied by the text, or merely set the value of a variable, which is
implied by the example?

I apologize for these elementary questions.
