When you look up a *host*, you look for A/PTR or CNAME. When you look up an MX, you can look up an MX for a *domain*, *or* you could look up an MX for a *host*. I expect in most cases if you query for MX for SMTP*Host* you'll get nothing -- I wonder how many admins define MXers for each host these days. It shouldn't need FQDN though, it should add search domain suffix(es) from /etc/resolv.conf. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
