 > Interesting. Nice find, isis!

 Definitely!

 This will be (sadly) very difficult to fix, however. We do handle the '+'
 notation already:

 {{{
     idx = localpart.find('+')
     if idx >= 0:
         localpart = localpart[:idx]
     rules = domainrules.get(domain, [])
     if 'ignore_dots' in rules:
         # j.doe@ is the same as jdoe at .
         localpart = localpart.replace(".", "")

     return "%s@%s"%(localpart, domain)
 }}}

 So, limiting "incrementing" addresses and "similar" addresses is the next
 challenge. I fear it will be a losing battle.

 Interesting thought, it's something we can look into and experiment with.
