Yes, if someone takes the time to come up with some common ones then please share The problem is that so many scammers seem to buy these mis-spellings and hold them with no MX record set and so the poor user who mistypes effectively see's their message sit in the postfix queue for 5 days (or whatever your timeout is set to) and then 5 days later gets a notice about an email they probably forgot they wrote by then... Instant rejection would be helpful for some mis-smellings (I already have a small transport map which maps to "ERROR: probably you mistyped that email address?") Ed
