disallow Trash mails

[Tealk]

Hello,

would it be possible to include a field in which you can insert a trashmail list?

Hello, could you define what trashmail is?

Hi sure
like this one https://www.trash-mail.com
there are many lists like this one https://github.com/teklab-de/Trashmail-List/blob/master/trashmail.lst

it would be grate if you would add a field that a user can add its own list

Related to #160 I guess and afterwards it's just an additional setting.
