are you saying the subject is 3 lines (not one long line that wraps
over 3) before you try to send it as email?

if so you need to strip out the newlines (or CR/LF) or whatever is
there as linebreaks.

Have a look at the "tr" command, possibly the -d option.

echo "now  
time" | tr -d "\12\15"

prints "now is the time" but note that there is no newline at
the end of the string, so you'd need to add one back.

if you do this, you get the trailing newline, though this looks
pretty weird:

/usr/bin/echo -e  `echo "now 
time" | tr -d "\12\15"` 

good luck!
