permanently delete all emails from *@domain.com in a mailbox - how with one command?

[n8schicht]

Hello,

i want to delete some mails from one of our mailbox.

i want to delete:

*@mail.de

*@mail2.de

The mailbox is over 6 years old and every year we receive tons of mails from these mail-adresses. 
now we don´t need them and can delete them ?

How can i permanently delete them and not move to the trash with one command?

thx

Martin
