Can we set the message_size_limit for new Email role installs as its using the default Postfix setting of 10MB at the moment which is pretty small by todays standards. If this could be initially set to 35MB or 50MB or even better make this an option we can set in the UI. For now I would be happy with just increasing this to 50MB for all new Email role installations.
For those of you who want to increase it now to 50MB you can use this one liner:
sudo postconf -e 'message_size_limit = 51200000' && sudo postfix reload
