Notice when send message

[soromir]

Good afternoon.
How it is possible to realize the task.
I need to check the message before sending to the nesting file if the file is there and there are words in the body of the message
attach attachemnt, it's necessary to print notice "you forgot to attach the file".
Example gmail

roundcube ships with a plugin called attachment_reminder so all you should need to do is enable it in your config
