mutt is a (good) SL-distributed alternative:
mutt -s "subj" -a attach whoever@wherever  <whatever

'whatever' needs to be present in some way (|,<,<< etc; but 
whatever=/dev/null should also work), or mutt will invoke an editor 
rather than sending it off ...

With mail/sendmail you probably don't have a choice other than
uuencoding the attachment and send it along as plain text, which has
however a fairly good chance to get trapped by a spam-filter...

ciao, Frank.
