The mail-system was moved from the webserver to an standalone webserver.
System mails like login or webform mails (plain text) are working also when I try to send a testmail with the DefaultMailSstem

The webserver is delivering the mails with sendmail to the mailserver realy,with username and password.

When I am trying to send the mails with html I get the error in the syslog "Mail sending failed because:@mail":

It was working with postfix on the same server before, but postfix was disabled and changed by sendmail.

Same problem here. Since a few days I can't send mails from my site.
example debug details: (everything between [] has changed by me)

Mail sending failed because:

@mail([mail], [title], ..., MIME-Version: 1.0
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: 8Bit
X-Mailer: Drupal Webform (PHP/5.3.10-1ubuntu3.19)
Return-Path: [mail]
Sender: [mail]
From: "[name]" <[mail]>, -f[mail])

returned FALSE.

The type of the error is htmlmail. It's a sidewidth problem.
The mails are also never shown up in the maillog table.

what could be the problem?

You must have changed something which is causing the problem now...

It seems that no one has an answer so far, but you are our best hope.

After much searching I found the answer:
The email (email_field) module was the problem.
After I had disabled it, I could send mails again.

I hope this can help others with the same problem!
