Folks,
G'day.
From ICANN SSAC SAC 053
(www.icann.org/en/groups/ssac/documents/sac-053-en.pdf):
"3.4 Electronic Mail One serious and prevalent concern is that
dotless domains would not work with protocols that specify additional
rules of what constitutes a legal domain. The most prominent example
is the Simple Mail Transfer Protocol (SMTP) to deliver electronic
mail. It requires at least two labels in the FQDN of a mail address.
Thus standard-compliant mail servers would reject emails to addresses
such as user@brand."
I'm not seeing this requirement/limitation in RFC 5321. It merely
requires an FQDN.
Does anyone have an explanation for the assessment in the ICANN report
that at least two levels are required?
