Funny part is that this submission made it to the front page again... I guess this is a really popular topic?

#8Following this advice creates a lot of "I never got my activation email" and "Why won't it let me log in" support emails that are a big pain to deal with. It's pretty important to nip that in the bud, hence immediate email address validation.

#9If you've been developing login systems for any length of time, this should be fairly obvious.
Be careful about taking that "it’ll get bounced" attitude too far though. The last time I did so I forgot to trim the email addresses and didn't lowercase them. Failing to trim will probably result in the email going through, but then might cause problems later on when you try to match their login ID to what they enter the next time.
A similar issue arises for case. Email addresses are supposed to be case sensitive but providers don't seem to take advantage of it in practice. Again, the case a user types varies from time to time (I assumed nobody used upper case... it seems silly). And if you switch to case insensitive login IDs down the line, you may have to deal with duplicate accounts (same email but different case).
