Losing Data Blocks

[david6633]

I am not sure if this is sendmail related or not - just hoping that someone may be able to point me in the right direction.

The problem that I am having is that on some incomming mail servers blocks of data are being lost. I have fairly good proof that it is the mail server that is doing it and not the program. These are hosted servers and I am at a total loss as to where to start looking.

If anyone can help I would be grateful.

Do you know if this happens to only certain types of data such as html code or attachments? I'm suspecting that it may have more to do with virus scanning and/or spam blocking software on the server rather than sendmail itself.

It is the html code.

My guess would also be along the lines of anti virus/spam too.

If that is the case would you know of any way to stop losing the data?

Although sendmail can be set to allow plain text only, I can't imagine a mail provider blocking html. They may have something misconfigured. Otherwise there service would be pretty much useless. Are you sure it's not on the client end? You said earlier that you were pretty sure it is the server. What makes you say that?

The reason that I say it is on the server is that I have had a user with two email addressess which are on different servers. With one of his addresses the email was always comming through corrupted but on the other it was fine. When he swapped the email addresses over then the situation was reversed - good became corrupted, corrupted became good. This to me seems to point to the incomming mail server.
