Got a fairly unhelpful error while trying to send an emailĀ using LuaSec and LuaSocket to connect to googles SMTPĀ servers:
555 5.5.2 Syntax error. uc3sm9880237wib.2
Turns out google doesn’t like the recipient format
‘FirstName LastName <name@example.com>’
and instead prefers just
‘<name@example.com>’
