ssmtp will leave dead.letter behind if it cannot reach the configured 
relay MTA. But not only ssmtp creates dead.letter

ssmtp installs /usr/sbin/sendmail.ssmtp and ln -s it to 
/usr/sbin/sendmail via the standard alternatives system:
postinstall scriptlet (using /bin/sh):
/usr/sbin/alternatives  --install /usr/sbin/sendmail mta 
/usr/sbin/sendmail.ssmtp 30 \
        --slave /usr/bin/mailq mta-mailq /usr/bin/mailq.ssmtp \
        --slave /usr/bin/newaliases mta-newaliases 
/usr/bin/newaliases.ssmtp \
        --slave /usr/share/man/man1/mailq.1.gz mta-mailqman 
/usr/share/man/man1/mailq.ssmtp.1.gz \
        --slave /usr/share/man/man1/newaliases.1.gz mta-newaliasesman 
/usr/share/man/man1/newaliases.ssmtp.1.gz \
        --slave /usr/share/man/man8/sendmail.8.gz mta-sendmailman 
/usr/share/man/man8/ssmtp.8.gz

it never replaces exim unless told to, because exim is preferred by yum. 
actually you MUST install ssmtp ON PURPOSE, it never comes as the first 
choice and the priorities are chosen as to be less preferred when 
compared to sendmail or postfix. However I have no idea how does exim 
handle this. sendmail is the default mailer chosen by anaconda, which 
gets replaced by exim or postfix if one chooses to not install sendmail. 
you have to try really hard to install ssmtp and it's on purpose like that.
