Or should I always ensure that resolvers reach my domain explicitly by including the trailing "dot" in all uses, so that my email would be given out as "myname@smtp." in the hopes that everyone would correctly remember to add the "." at the end when entering my email address into their mail clients?
Trailing dots in email addresses are a syntax error.
In the past, this wasn't really a concern, as you never had a case of a single entity owning an entire TLD, and as such you'd never see A or MX records showing up for an entire TLD.
Not true. There have been TLDs with MX and A records for a long time, though they tend to be badly set up, and many MTAs treat single-component domains specially such that email to these TLDs will often not work. http://fanf.livejournal.com/72486.html Tony. -- f.anthony.n.finch <dot@dotat.at> http://dotat.at/ HUMBER THAMES DOVER WIGHT PORTLAND: SOUTHWEST BACKING SOUTHEAST 3 OR 4, OCCASIONALLY 5 AT FIRST AND LATER.
