Ajuda com o sendmail

Pessoal:
Instalei o sendmail, mas estou tendo problemas para enviar e-mails.
Explico:
Instalei o servidor sendmail em uma máquina em casa (ip dinâmico), mas não consigo acertar a configuração do arquivo . A máquina não consegue enviar e-mails.
No caso, minha máquina em casa, tem o nome: cefalosporina.net
Tenho uma conta no no-ip para validar o e-mail em caso de consulta ao dns reverso.
Meu arquivo sendmail.mc está assim:

Como pode ser viso, existe:
relay=smmsp@localhost.localdomain [127.0.0.1]
mas smmsp@localhost.localdomain [127.0.0.1] não existe.

Os e-mails são gerados por cron (programado pelo crontab).
Entre 0 horas e 8 horas da manhã e entre 12 e 14 horas, se houver movimento em frente a uma das câmeras, o sistema envia um e-mail.
No crontab, existem as linhas:

0 0,12 * * * root /bin/touch /root/mov_cap_enable
0 8,14 * * * root /bin/rm /root/mov_cap_enable

Eu uso o motion para o sistema de segurança, e, ao detectar movimento em frente uma das câmeras, ele grava o filme relativo ao movimento e, se existir o arquivo /root/mov_cap_enable, ele envia um e-mail com a cópia do filme.

no arquivo de configuraçã do motion, em /usr/local/etc/thread2.conf coloquei a linha, ao final:
on_movie_end /sbin/email.sh "%f"

O conteúdo do script email.sh é este:

#!/bin/sh

if echo "$1" | grep -q '.avi'; then

if [[ -e /root/mov_cap_enable ]]; then
( cat /root/mensagem.txt
uuencode $1 movimento.avi
) | mail -s "$1" somebody@somewhere.com;
echo $1 >> /root/emailmovimento.log;
fi;
fi;


Obrigado por qualquer ajuda.
