hippriest commentedThis is not a typo. "An" is used preceding words that begin with a vowel sound- and this rule applies even with acronyms that begin with consonants. Saying the letter "S" is the same vowel sound in the first syllable of the word "estimate" (for example). Just as you would write "an estimate," you would also write "an SMTP."

Relevant example:
Articles with Acronyms, a or an
Finally, the rule applies to acronyms as well. If you pronounce a letter as a letter and it begins with a vowel sound, you should precede it with an. The consonants with vowel sounds include f, h, l, m, n, r, s, and x.
