Due to the trouble of the spam mail detective server in this university, some of the sent mails from Dec.10(10:40) to Dec.11(19:43) were deleted by accident and weren't sent correctly.We are very sorry.

We had sent the date, recipients' mail address, and subject of the deleted mails through the e-mail(Subject:Apology for the trouble of transceiving mails) as of Dec.12.

The cause of the trouble had gone and all users can use it as usual now.
We aplogize for the inconvenience.
