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.
RFC 2822 3.4 punts the components of dot-atom to STD 3/13/14. STD 13 is RFC 1035, which, in 2.3.1, suggests (but does not impose) a standard for domain name literals which appears to expand to a pattern which does not in fact permit a trailing dot. In fact, Mutt (1.2.5) permits the trailing dot, and delivers the mail, and all the intervening MTAs (I only tested local mail on my machine, running Postfix) let the message through -- it came through apparently having been rewritten by Postfix to lose the trailing dot; there was an X-Original-To header.
