Now watch the mail log and see everthing addressed to go to /dev/null tail -f /var/log/mail.logĮxample log entries for an email going to /dev/null: Jun 27 15:09:09 fake postfix/smtpd: connect from .com Postmap /etc/postfix/vmailbox echo "virtual_mailbox_domains = fakemail.ca" > /etc/postfix/main.cfĮcho "virtual_mailbox_base = /var/mail/vhosts" > /etc/postfix/main.cfĮcho "virtual_mailbox_maps = hash:/etc/postfix/vmailbox" > /etc/postfix/main.cfĮcho "virtual_minimum_uid = 100" > /etc/postfix/main.cfĮcho "virtual_uid_maps = static:5000" > /etc/postfix/main.cfĮcho "virtual_gid_maps = static:5000" > /etc/postfix/main.cfĮcho "virtual_alias_maps = hash:/etc/postfix/virtual" > /etc/postfix/main.cf Postmap /etc/postfix/virtual echo /dev/null" > /etc/postfix/vmailbox
Now we can configure aliases and postfix. # on the "Internet protocols to use:" screen, choose whatever applies to you. # on the "Local address extension character:" screen, accept the default "+". # on the "Mailbox size limit (bytes):" screen, accept the default "0". I can delete it and login with my usual email but when I goto my settings and view my primary email address it appears blank. When I go to login on my laptop this email address appears instead of mine. # on the "Force synchronous updates on mail queue?" screen, select "No" because we don't care about the mail queue. My facebook email address has been hacked and changed to the format: where the 'n' is a number.
# on the "Other destinations to accept mail for (blank for none):" screen, remove your hostname from the list so that it reads "localhost, localhost.localdomain" # on the "Root and postmaster mail recipient:" screen, leave the field blank. # on the "System mail name:" screen, accept the default of "localdomain". # on the "General type of mail configuration" screen, select "Internet Site" You will probably only see the first two unless you do a 'dpkg-reconfigure postfix'. # Use the below as a guide for any configuration questions.
Blackhole devnull facebook email install#
Install postfix apt-get -y install postfix
Blackhole devnull facebook email update#
Log in as root and make sure you’re all up to date: apt-get update & apt-get upgrade I started with a canned Debian 9 system at OVH, but this should work with other and older Debian versions too. Steps:- go to facebook settings- when you confirm blackhole make sure not to enter your password- remove your email and add a new email or you can still use. Requirement: Build a web server that will receive email for a particular domain and discard it immediately (and silently).
