I need exim to allow messages larger than 20 Megabytes Last Modified: Apr 7, 2016, 9:49 pm

The default setting in the /etc/exim.conf for the message size limit is: message_size_limit = 20M You can edit the /etc/exim.conf and increase this value as needed.  Restart exim after changing the value /etc/init.d/exim restart SpamBlocker 4.x+ Newer exim.conf versions will use the /etc/exim.variables.conf file. To change that, edit /etc/exim.variables.conf.custom using the custom variables guide to add: message_size_limit=500M or whatever you need, then run: cd /usr/local/directadmin/custombuild ./build exim_conf which should rebuild the exim.variables.conf If you're using ClamAV, you'd also need to match the StreamMaxLength setting in /etc/clamd.conf, to the message_size_limit.
