[TYPO3-english] SENDMAIL problem / error

[Vincent Mans]

Hi!

Sendmail causes problems. So I can't use the new form mail. I have
this on two different servers (Gentoo and Ubuntu).

"[MAIL][transport] = mail" goes well. Testmail is sent. Real mails are sent too.
"[MAIL][transport] = sendmail" gives this error in the backend,
testmail: Oops, an error occurred! Expected response code 220 but got
code "", with message ""

The mailform isn't sent from the website: "There was an error when
sending the form by mail".
