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 ip4:22.214.171.124 ?all"
solentmotorgroup.co.uk internet address = 126.96.36.199
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 = 188.8.131.52
ns1.snowweb.info internet address = 184.108.40.206
ns2.snowweb.info internet address = 220.127.116.11
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 18.104.22.168 instead of our customers at 22.214.171.124
The DNS information for solentmotorgroup.co.uk is below:
ftp A 126.96.36.199
localhost A 127.0.0.1
mail A 188.8.131.52
pop A 184.108.40.206
solentmotorgroup.co.uk. A 220.127.116.11
www A 18.104.22.168
www.mail A 22.214.171.124
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 ip4:126.96.36.199 ?all"
Does anyone have any suggestions please?
Thanks in advance.
