So as a workaround, you can do: --to='"LASTNAME, firstname" <firstname.lastname@xxxxxxxxxxx>' I think rfc822 actually requires even names with just spaces in them to be quoted, but git-send-email and most other mail programs are pretty lax about allowing just about anything outside of the <>, so people tend not to bother. > If the string preceding a comma is not a valid email address do not > split it off. That might work as a heuristic, though "is a valid email address" is a notoriously hard thing to check. Possibly looking for an "@" would catch most common cases, though. -Peff
