求助UIUC,CS说可以把GRE成绩自行发给他们但发送始终失败

UIUC admission页原话如下：
The Graduate Record Examination (GRE) general aptitude tests (Verbal, Quantitative, and Analytical) and subject test scores are recommended, but not required. In some cases, the scores may provide helpful supporting information. Applicants may email a scanned electronic copy of their official scores directly to 1point3acres.com (MCS-DS applicants: 1point3acres.com) or they may have official GRE scores sent via ETS.

但是我发给他们这个1point3acres.com的邮件都被自动退回，退回邮件如下：
