When sending a mail with attachments that result in php running out of memory, roundcube will log an error to its log: "PHP Fatal error: Allowed memory size of 15728640 bytes exhausted...".
However there is no notification that anything has gone wrong for the user as the browser just hangs on "Sending message..." for a while and then leaves the user at the compose screen for that email.
Is there any option within the config that will force this error to be shown, I can only see "$rcmail_config['debug_level']" within the config file which just affects how the error is logged by roundcube or php.
(And I know that to fix the actual issue I just need to bump up the memory_limit assigned to php.)
Cheers,
Tom
