Difficulties e-mailing psycholegal?
If your emails bounce back then a likely cause is
reverse DNS, a device put in place by internet providers to combat
spam. For some reason this is more common for e-mails sent from
Northern Ireland and the Isle of Man. See below for an explanation
Forward Confirmed Reverse DNS (FCRDNS)
This has been implemented by our internet provider to reduce junk email
passing through their servers.
Both the forward and the reverse DNS entries must match each other.A
reverse DNS lookup is completed by our internet provider to get a list
of the PTR Records. For each of the PTR records that is returned a
regular Reverse DNS lookup is completed to see if any of the A records
match the original IP address. If there is a forward DNS lookup that
confirms one of the names given by the reverse DNS lookup, then the
FCrDNS check passes those allowing email into the server.
Many companies are bringing this into place to combat spam.
If you are getting a bounce back message saying you have
hostname and giving you an IP address then the IP you are sending from
does not have FCRDNS set-up. This can be set-up by contacting your
server administrator or by contacting your internet provider.
