I'm seeing the following error message:

Jul 7 11:48:06 MacMini postfix/smtpd[71904]: can't access srvtab file krb__get_srvtabname() is no longer supported.: No such file or directory
Jul 7 11:48:06 MacMini postfix/smtpd[71904]: SQL engine 'mysql' not supported

I've tried re-installing cyrus-sasl but it doesn't seem to help. I'm running a PPC Leopard v10.5.4 MacMini with Postfix 2.5.2.

Any ideas?

Oh and MySQL is version 5.0.51b.

And I seem to be able to send and receive emails okay.

Paul, this isn't really a problem. To make the error go away just create an emtpy file with the same name and all will be fine.

Create a file with the name "krb__get_srvtabname() is no longer supported."?

No sorry, I meant create the file /etc/svrtab without anything in it and the error will dissappear.
