... when talking to ironportmailer1.fujixerox.co.jp:

& gt& gt& gt from: & ltplfanjuan@yahoo.com.cn size = 27352662 body = 8 bit mime.

& lt& lt& lt exceeds the size limit of 552.

554 5.0.0 service is not available.

If the sending is unsuccessful, the other party's server cannot be used, because the file size you sent may exceed the size limit.

Permanent fatal error
