hi,all!

here is some messages i received.

I received the following message for delivery to your address. This message contains several internal formatting errors. This is often caused by viruses that attempt to infect remote systems. Instead of blocking this message, I converted it to a safe, text-only attachment that can be safely read with a text editor.

This sometimes also happens when the sender's mail software has a bug that creates improperly-formatted messages. Although these kinds of formatting errors may often be ignored by other mail servers, this server detects and intercepts improperly-coded messages in order to prevent viruses from taking advantage of bugs in E-mail programs:

----------------------------------------------------------------------------- The headers in this message contain improperly-formatted binary content.

See <URL:ftp://ftp.isi.edu/in-notes/rfc2047.txt> for more information.

how to? thank you!
