centos sendmail AUTH=client, available mechanisms do not fulfill requirements

I'm running centos-6.7 (command line only) with sendmail-8.14.4-9.el6.x86_64. I can't send emails, I keep getting an error in the maillog for each send attempt which says:
stat=Deferred: Temporary AUTH failure <snip> AUTH=client, available mechanisms do not fulfill requirements <snip> temporary failure, connection abort.
I've been trawling google but I can't find a solution, I get the impression I'm missing some kind of sasl component but I don't know what it is and I can't find a centos-based solution. Thanks for any help.
