A malformed MIME structure with many parts can cause sendmail to
crash while trying to send a mail due to a stack overflow,
e.g., if the stack size is limited (ulimit -s). This
happens because the recursion of the function mime8to7()
was not restricted. The function is called for MIME 8 to
7 bit conversion and also to enforce MaxMimeHeaderLength.
To work around this problem, recursive calls are limited to
a depth of MAXMIMENESTING (20); message content after this
limit is treated as opaque and is not checked further.
