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. Haines Brown
