Trying to send mail with PHP Mail / Postfix / Ubuntu

I have just installed Ubuntu server and have installed postfix  i am just wanting to be able to send mail via web forms , however this does not work via PHP forms or by commandline

I can login to WEBmin and send mail which works ok,

The errror message when mail fails is
said: 550 authentication required (in reply to RCPT TO command)

Any help on where to start looking or configuration settings to check would be appreciated

Regards

This means you need to configure SASL auth in postfix config and post that you need to use while sending out the mails.

If it is   Outgoing SMTP Authentication , please take a look at this
http://wiki.zimbra.com/index.php?title=Outgoing_SMTP_Authentication
And do the command as this:
su - zimbra
postconf

check your value's of these across the board
smtpd_use_tls
smtpd_tls_auth_only
smtpd_tls_key_file = /opt/zimbra/conf/smtpd.key
smtpd_tls_cert_file = /opt/zimbra/conf/smtpd.crt

If you want to get some more output: smtp_tls_loglevel
1- Disable logging of TLS activity.
2- Log TLS handshake and certificate information. (what you have currently)
3- Log levels during TLS negotiation.
4- Log hexadecimal and ASCII dump of TLS negotiation process.
5- Log hexadecimal and ASCII dump of complete transmission after STARTTLS.

Hope understand your question completely.If not, please ,point it out

No, you don't need it.. i believe you postfix setup is fine.. just use client auth from mail client to send the mails ...

Which client you are currently using ? check there must be option to send the messages with auth.

Ok problem is fixed, I installed sendmail via the WEBmin panel rather than command line as i had been doing previously and everything just worked, no idea why except that posssibly a module was not installed via commandline that was installed by WEBmin.
