FWIW
The "compose" dialogs on Microsoft Outlook 2010, Yahoo! Mail, Live.com, and
Gmail do not allow dotless domains. Yahoo and Live.com reject the address as
malformed; Outlook tries to look it up in the local address book; Gmail gives
an error on send.
Thunderbird 2.0 to my employer's Exchange server (over SMTP) worked fine --
and then the message got rejected by the corporate firewall as "invalid
domain."
Yeah. Over in Mac land, no warning on dotless domain, but iCloud's Oracle
servers then tried to qualify the domains and hence failed. The username-only
form "foo" just puts up a "This looks wrong, continue anyway?" type dialog.
Continue and the SMTP server gets it as is.
On iOS (iPhone, iPad, iPod Touch) the "This looks invalid, send anyway?" dialog
comes up in both the bare user and dotless domain cases.
In Postfix, both append_dot_mydomain and append_at_myorigin are both set Yes by
default. So both cases are taken care of.
So yeah, stiff resistance from the front lines.
