正文:

电子邮件正为中所包含的内容会根据数种文本选项而不同。 {}括号内的句子与词以"|"分开:

* Dear user {|of

would like to {inform you{ that{:|,}|}|let you know

{that|the following}{.|:|,}}|||||}

{We have {detected|found|received reports} that y|Y}our {e{-|}mail

{{unsolicited{ commercial|}|junk} e{-|}mail|spam}{ messages|} during

* {The|This|Your} message was{ undeliverable| not delivered} due to the

following reason{(s)|}:

Your message {was not|could not be} delivered because the destination

{computer|server} was

{not |un}reachable within the allowed queue period. The amount of time

a message is queued before it is returned depends on local configura-

tion parameters.

Most likely there is a network problem that prevented delivery, but

it is also possible that the computer is turned off, or does not

have a mail system running right now.

* Your message {was not|could not be} delivered within

days:

{{{Mail s|S}erver}|Host} } is not responding.

The following recipients {did|could} not receive this message:

The original message was included as attachment

* {{The|Your} m|M}essage could not be delivered

注意:

the email.
