I believe I have determined the program which has been
causing subtle corruption of POP mailboxes. I and others
have observed it as altering a sequence of "!" characters
to randomly inserted double-quote characters.
In the following examples, I mailed a message consisting of
lines of "!"s to a host which performs both POP and regular
mail delivery. The messages delivered with /bin/mail are
untouched, but the ones delivered with /bin/spop exhibit
the corruption.
The bug is serious as it obviates the proper reception of
binary --> ascii encoded data, such as uuencoded or binhex'd
files.
