The fact that it can be done outside of Gnus doesn't alone make a good case that it shouldn't also be possible to do it within Gnus.

RFC 1034 doesn't use the term "fully qualified", but it does use "absolute" and "relative". A domain name is a sequence of labels which, in text representation, are separated by dots. An absolute domain name is one whose last label is the empty string, which designates the root domain - thus, its last character is a dot. Anything else is relative, and is subject to absolutification according to local configuration. (Also, there is no notion of a "hostname" which is different from "domain name"; a hostname is simply a domain name with an address record, and the term "hostname" is not used in the DNS RFCs.) In practice, people think of a domain name containing a dot *anywhere* as being absolute ("fully qualified"), and only those with *no* dots as being relative. The only reason people can get away with this is because their own local configurations make it work. The name "www.gnus.org." is absolute, but the name "www.gnus.org" is not. The most common way of making it absolute is to first try it in the root domain (i.e., just add a dot at the end), and then if that fails, try it in the local domain(s). OTOH, the name "www" is usually looked for first in the local domain(s) and then in the root. But the presence of an internal dot only affects the local absolutification configuration, not whether the name is absolute to begin with. I've set user-mail-address to end with "." (I think this violates 2822, but I won't care until it actually breaks something), and I set message-syntax-checks to include (from . disabled), but my From fields still have no trailing ".". :( Anyone know how to do this? I don't want to depend on others' local configurations. paul
