Owners of new .capetown top-level domains may have some trouble using e-mail addresses from their new space on the Internet.
This is because a number of online services still check to see that the top-level domain (TLD) portion of an e-mail address (such as .com, .net, or .za) is only a certain number of characters long.
Even well-established, widely used open source Internet software checks for TLD lengths as short as 6 or 7 characters, despite an old Internet Engineering Task Force document, Request for Comments: 1034 (published in 1987) specifying that TLDs could be up to 63 characters long.
One example of a site in South Africa that only validates e-mail addresses which are much shorter than specified in RFC 1034 is the First National Bank (FNB) online banking site.
FNB checks that a TLD is no longer than 7 characters, according to the error message it spits out when you try to use a firstname.lastname@example.org e-mail address.
FNB was asked why it validates e-mail addresses in this way, but the bank did not respond by the time of publication. Read more from mybroadband.co.za
