Out-of-the box Bind 9.2 thru 9.4 has no problem with underscore SRV 
records (required for Kerberos details) or TXT records (required for 
Domainkey and DKIM details). But I had a hell of a job initially in 
getting our large Dutch ISP to change his system to accept entering of 
underscores in TXT records, he didn't want to at all, did in the end.
