is it doable ?

Hello!

To do this you'd need to set up a custom Exim system filter rule. Documentation on how to use the Exim system filter can be found here:

Thank you,

acl_check_rcpt:

deny

senders = lsearch;/etc/exim/restricted_sender
domains = lsearch;/etc/exim/restricted_domains

/etc/exim/restricted_sender

Hello! While we offer an interface for configuring Exim, the actual configuration of the filters would be something I'm not sure about. Perhaps other users can assist with this.
