It is interesting, for sure, that they are using a gmail.com email address for a role account apparently currently for which the recipient is CPT John Hutchison as of May 2025 [0]
But that's not what actually inspired me to write this reply I thought some of you may enjoy reading about.

Incidentally, the dot in the local recipient part of that NSA veterinarian address brings something of a fond anecdote to mind: Since for a gmail SMTP address at delivery time, (excluding organizationally-managed Workspace addresses) "dots" do not matter in the LHS of a recipient address [1], this gmail account address (since it is in the gmail.com domain) would actually be just "nsabahrainvetclinic[at]gmail.com", and the dot seems only to be a visual cue to make its meaning clearer for the human reader/sender. But that's just a preface to my actual anecdote.

More preface: Gmail account names (the LHS) must be at least six characters in length when the account is submitted for creation. [2]

As an early adopter from the Gmail invite-only beta stage, I was able to obtain my long-held, well-known (by my peers) 7-character UNIX login name @gmail.com without issue, which consists of my five-letter first name followed immediately by a two-letter abbreviation of my lengthy Dutch surname, as had been used for years as my Unix login (and thus email address) and sometimes as my online forum handle.

In this early day of gmail, I wanted to "reserve" similar short, memorable, and tradition-preserving usernames for my children, who would soon be entering ages where having an email account would be relevant for them and I was in a position with my allotment of invites to secure such "good" addresses for them. For my daughter this worked out easily as her first name plus surname abbreviation worked out to exactly six characters. For my son, this seemed to not be possible since his given name was only three letters long, and 3+2 being 5, meant that creating a gmail account for him, following my newly-imposed family standard naming scheme seemed impossible.

So, on a hunch following a scent of there possibly being something I could exploit here (and slightly influenced by the burgeoning non-Unix-login-length character imposition corporate trend of first.last[at]domain address standardizations), hypothesizing a letter-correct gmail web front-end implementation that might allow me to spirit-violate backend behavior to achieve my goal, I followed through and successfully got my son's gmail address past the first criteria that a new account must be at least six characters by creating his address as his three letter first name, followed by a "dot", with our two-letter abbreviation of our long surname at the end; something like abc.xy@gmail.com. And my hunch paid off, for as described in [1], the dot was simply ignored at SMTP address-parsing and delivery (and mayhaps also/because at username creation/storage time, but that's just a guess; I'm unsure how/why it actually worked at a technical level since I did not work at Google), giving my son the ability to effectively have a five-letter gmail "username" in his address, in the intended "first name followed by last name two-letter short form" I had created for my progeny, simply by omitting the '.' From his username when sending him email to his gmail address! :-) (My son, sadly has since passed - RIP my sweet boy Ryk; I miss you terribly every day) and I have no idea if this technique is still exploitable in this way today.

I did later wonder if I could have done similar using the fact that "+anything" is ignored in the LHS when parsing a gmail delivery address to maybe pull off creating a three-letter username for a gmail account for my son back then, but never actually tried it when it could have been trivial to try to exploit that sort of front-end-validation vs backend implementation technique for gmail addresses. shrug

I hope y'all don't mind my little off-topic tangent and enjoy the story of this afaik little-known feat that could be pulled off, at least for a time.
