FYI: https://mail.google.com/support/bin/answer.py?answer=10313&topic=1564 that was the only reference i found, http://www.ietf.org/rfc/rfc0821.txt doesn't mention anything beside EXPN which still treats the localpart literally and checks for a mailbox (or alias) as literally found in the localpart. Personally I think google's doing wrong here. Just don't do it anywhere else, as it's unlikely your mail will reach the person you intended to send it. -- http://noneisyours.marcher.name http://feeds.feedburner.com/NoneIsYours You are not free to read this message, by doing so, you have violated my licence and are required to urinate publicly.

Try the SMTP spec. IIRC there's a passage there that says that the server should try to make sense of addresses that don't map directly to a user name. Specifically, it says that firstname.lastname should be mapped to the user with those first and last names. -- [EMAIL PROTECTED] http://www.librador.com -- http://mail.python.org/mailman/listinfo/python-list

It's quite useful - apart from using it to determine which site I signed up to has sent me mail, I also use it so I can have multiple Guild Wars accounts using the same email account e.g. [EMAIL PROTECTED] [EMAIL PROTECTED] All resolve to @gmail.com.

Technically, everything in the local part of the address (the bit before the @ sign) is supposed to be interpreted *only* by the host given in the domain (the bit after the @ sign). So if Gmail wants to interpret "[EMAIL PROTECTED]" and "[EMAIL PROTECTED]" the same, they can. Or for that matter, "[EMAIL PROTECTED]". Although that would be silly. Postfix, I think, interpets "foo+bar" the same as "foo". -- Steven -- http://mail.python.org/mailman/listinfo/python-list

This is a feature of some mail services such as Gmail, not of email addresses generically. One use is to provide a set of addresses given one base address.

That is plain wrong and would break a lot of mail addresses as I have 2 that follow just this pattern and they are delivered correctly!

The localpart of an email is entirely up to the receiving mailserver and cannot be tempered with without risking misdelivery (at least). If I'm wrong I'd be gladly corrected, just point me to the references. /martin -- http://noneisyours.marcher.name http://feeds.feedburner.com/NoneIsYours You are not free to read this message, by doing so, you have violated my licence and are required to urinate publicly.

Looping through the gmail dot trick
So I have a very interesting task ahead of me and it is to loop through an email using the 'gmail dot trick'. Essentially this trick puts periods throughout your email to make it look different. Even though it has periods gmail will replace them all and send it to that email. So [EMAIL PROTECTED] is the same as [EMAIL PROTECTED] My task is this: Loop through an email and create as many combinations of periods as possible. So all the combinations for blah would be: b.lah bl.ah bla.h b.l.ah b.la.h bl.a.h I'm still rather new to python so this is turning out to be rather tricky. My current code is as follows: for d in range(1, len(email)): > for i in range(1, len(email)): > y = i > temail = email > for x in range(d): > if email[y] == '.': break > temail = temail.replace(email[y], '.' + email[y]) > if not y > len(email) - 2: y += 1 > print temail > It's not looking too bad except for some reason it's making emails like bl..ah which is invalid. So can anyone help me out with getting this to work? Thanks. Cheers, Josh -- http://mail.python.org/mailman/listinfo/python-list
