[PATCH] sendmail: EHLO/HELO should use a domain

[Natanael Copa]

Hi,

Finally I'm taking a closer look at replacing ssmtp with busybox
sendmail. Attatched is a patch (against 1.12.0) with what i needed to
make it work.

Most serious issue was the fact that current bb sendmail uses the from
address in the EHLO/HELO message. The rfc1869 (section 4.2) says it
should be a domain not an address. So my MTA correctly dicarded the
invalid EHLO. I solved this by using the domain part in the from
address. This requires that the from address has an '@' which i think is
ok in todays world (10 years ago it would be different)

Seconly, I added an -o option thats just ignored. It allows you to be
somewhat compatible: sendmail -oi ...

Third, the enviroment variable HOSTNAME is a "reserverd" variable for
bash so I changed it to SMTPHOST.

Sendmail is a good addition to busybox. Thanks!
