if u mange shared hosting server?s you?ll probably find one of ur server?s blocked by other mail providers because of high mail volume or one of your users spamming. To change your exim IP for outgoing mail, you can edit your /etc/exim.conf file and locate this section:

PHP Code:

remote_smtp:
driver = smtp 


And below this add:

PHP Code:

interface - xxx.xxx.xxx.xxx 


Replace the x?s with the backup mail IP. Note that the backup mail IP needs to be added to the server, and should have a valid PTR and A-record.
