I have tested the script on another server and it works fine.
When I check exim logs there are lots of rows like this,
User 0 set for local_delivery transport is on the never_users list
lots like this
routing defer (-51): retry time not reached
and even some like this
R=lookuphost T=remote_smtp defer (-44): SMTP error from remote mail server after RCPT TO:
I am pretty stumped to be honest.
All mail is fine when sending from webmail/outlook etc! I have full SSH and root access as this is a VPS. Any help would be much appreciated

Exim is trying to deliver the mail to a remote SMTP host and is failing. This is what the:
lines mean. It queues these mails up for retry, and skips through the mailq to see if it should attempt to redeliver any of these mails. It won't attempt this straight away, a predetermined timeout has to be reached. This causes:
Finally, when the max redelivery attempts is reached without success, it tries to deliver a mail to the postmaster (which by default is configured as root). However, the default exim configuration is to never deliver to root, so you get:
There's two problems here:
Firstly: exim can't deliver to this particular SMTP server. Either the destination SMTP server is broken, or Exim cannot deliver to any SMTP servers. Does exim deliver mail to address on other domains? You can test this on the command line with:
Secondly, you don't have a valid way for exim to report failures back to you. Configure your
/etc/aliases
file to make sure that thepostmaster
and other accounts are properly aliased to a real address.
