Sept. 5 - People who have applied for buying Olympic tickets are reminded to pay special attention to their email boxes, since the reply letter delivered by the Beijing Olympics organizer, BOCOG, may possibly be categorized as spam.Shanghai Youth Daily reported that some applicants, using email services offered by Hotmail.com, Yahoo China and 263.com have complained about the effect.A local citizen, surnamed Wang, told the paper that he fortunately noticed the BOCOG letter in his hotmail box having lent a glance over the spam column by accident.Wang was not the only person annoyed with the discreet filter function of his email system. One of his mates, a user of 263.com, was also close to a wrong deletion which was later avoided by recognizing the suffix of the sender's address, "beijing2008.cn."The BOCOG's reply letter is very important since it will confirm whether a buyer's bid for the Olympic tickets is valid or not.Valid bidders are required to make payments through Bank of China not later than September 30, otherwise, the order will be nullified, the report said.IT technicians said the problem likely owes to the strict anti-spam program designed by the email service providers. They advise applicants to re-check the safety level set in their email boxes or add the domain name of the BOCOG to the reliable list.An employee with the BOCOG ticket center said they will be sure to reply every ticket bidder, as long as a correct email address is available. However, applicants who miss the letter by wrongly deleting their mail will not be given a rain check, he added.
