Likely. Though at one point it wasn't unusual to configure the
separator to be - instead of + because of all the web forms that
didn't handle escaping properly and would record
"[email protected]" as "steve [email protected]".
A disturbing number of "ordinary people" (who don't live in SMTP
land) also believe that + is an "invalid character" in email
addresses.
And a disturbing number of programmers which make interfaces to record
email addresses still think the localpart isn't case sensitive.
I've given up on trying to tilt that particular windmill. There are too
many broken intermediate mailers (/spamfilters/middleboxes) that
lowercase email addresses before even sniffing the message.
