We host a website for a client who runs their own mailserver at their premises, so we have adjusted the MX record accordingly to direct incoming mail directly to their server. However, I notice in our mailserver logs that we are rejecting mail for their domain. The mail shouldn't be coming near our MX though. It's being rejected because the user accounts for the emails do not exist on our server (because they were created on the companies local server).
Here is a copy of an nslookup on the domain:
"v=spf1 a mx ip4:184.108.40.206 ?all"
solentmotorgroup.co.uk internet address = 220.127.116.11
primary name server = ns1.snowweb.info
responsible mail addr = root.solentmotorgroup.co.uk
serial = 2008060400
refresh = 14400 (4 hours)
retry = 3600 (1 hour)
expire = 1209600 (14 days)
default TTL = 86400 (1 day)
solentmotorgroup.co.uk nameserver = ns1.snowweb.info
solentmotorgroup.co.uk nameserver = ns2.snowweb.info
solent02.gotadsl.co.uk internet address = 18.104.22.168
ns1.snowweb.info internet address = 22.214.171.124
ns2.snowweb.info internet address = 126.96.36.199
When I do a perform a mailserver test using an online tool eg: http://mxtoolbox.com/ and I test our customers domain (solentmotorgroup.co.uk) into their diagnostic tool, it connects to our mailserver at 188.8.131.52 instead of our customers at 184.108.40.206
The DNS information for solentmotorgroup.co.uk is below:
ftp A 220.127.116.11
localhost A 127.0.0.1
mail A 18.104.22.168
pop A 22.214.171.124
solentmotorgroup.co.uk. A 126.96.36.199
www A 188.8.131.52
www.mail A 184.108.40.206
solentmotorgroup.co.uk. NS ns1.snowweb.info.
solentmotorgroup.co.uk. NS ns2.snowweb.info.
solent02.gotadsl.co.uk. MX 10
solentmotorgroup.co.uk. TXT "v=spf1 a mx ip4:220.127.116.11 ?all"
Does anyone have any suggestions please?
Thanks in advance.
