Is there any chance that you're running SpamAssassin on those large
messages?  That could cause the problems you're seeing.

You can set the maximum mail message size in the sendmail configuration
file.

The variable you need to define is confMAX_MESSAGE_SIZE.

    confMAX_MESSAGE_SIZE MaxMessageSize [infinite] The maximum size of
messages that will be accepted (in bytes).

The exact line you would put in your sendmail.mc file is:

    define(`confMAX_MESSAGE_SIZE', `10000000')dnl

How you turn your .mc file into a .cf file is system dependent.  I leave
that as an exercise for the reader.
