Hello folks,
There is a parameter
message_size_limit in exim configuration which defines the maximum email attachment size.
To check what limit set, run below command.
Quote#exim -bP | grep message_size_limit
To set limit open exim configuration file and enter the limit value that you wish to set on the server.
Quote#vi /etc/exim/exim.conf
message_size_limit = 30M (M stands for MB)
save the file and restart exim service.
Quote#/etc/init.d/exim restart
Hope this post will help you.
Enjoy !! :)
