SERVFAIL and lame server errors for google MX servers

[andys]

Hi, 

  thanks for your mail.
Yes I mean 9.5.0-P2 (its reported from FreeBSD pkg_info the way I wrote it). 
And no, I didnt have an explicit setting for max-cache-size so I strongly 
suspect that this will be the issue (I hope so!). 

Thanks a lot for your help, 

Andy.
