寄信問題釐清?

[mixmaster]

請問我們公司寄到另一家公司，對方無法收到，當然

我們雙方都正常可以收發其他內外部MAIL，因為之前都沒退信

所以拖很久才發現這問題，昨天又試驗今天有收到傳遞延遲

裡面有附件寫:

11/16/2010 11:11:25 Original attachment (ATT00444.dat) was Deleted. The original attachment was blocked from delivery due to current attachment blocking rules. You can safely save or delete this replacement attachment.

到底信進不過去誰的問題阿?

對方公司對於信件的附件有特定規則...
試著用"純文字"的方式寄看看?
像我對於HTML格式信件就有些感冒...
