MX check

[timill]

Could someone please check the MX records for smofs.org and timill.co.uk? I'm having strange problems with mailing lists ATM and a bad MX record might explain them.

It all seems fine from here, and on DNSReport and CheckDNS, except that Nominet thinks the authoritative name servers for timill.co.uk are ns.nothard.net and ns2.nothard.net, but those name servers think that ns3.nothard.net is also authoritative. But that shouldn't be causing you any MX problems.

Ta. My problem is that one mailer at lsoft.com can see me (so I can sub and unsub lists) but another can't (so I don't get any mail from the list). Looks like somethings gone bad there then.

MX looks fine, but....

You're advertising a single MX, and the mail exchanger isn't accepting SMTP connections.
