I have searched all over google for something to help me out on this....

The error...
dsn=5.6.0, stat=Data format error

Now I know this has to do with dns but I have gone through ever detail in bind
and in sendmail all the domains we host are listed.

Is there something in the sendmail.mc that we could have missed that needs to
checked ?

That does not mean that all of your mail has sender addresses in
resolvable domains.

I doubt it.

I believe you need to look at the context of that error. 5.6.0 is
typically returned as a rejection code when a sender domain is not
resolvable by a receiving MTA.

The full error is... (I munged the email address)

sendmail[25018]: l8KNbpRL025018: to=info[at]swisscart.com,
ctladdr=swisscart.com (1002/1003), delay=00:00:00, xdelay=00:00:00,
mailer=relay, pri=30283, relay=[127.0.0.1] [127.0.0.1], dsn=5.6.0, stat=Data
format error

The domain sending is swisscart.com

# host swisscart.com
swisscart.com has address 88.198.43.183
swisscart.com mail is handled by 5 mail.swisscart.com.

In console swisscart resolves just fine. What we figured out was php5 wasn't
doing something right in php mail().

What fixed it for us was setting the php value for sendmail...
sendmail_path = /usr/sbin/sendmail -t -i -f info[at]openstream.ch (Munged again)

Now email gets sent as it should. We still don't understand why the email
couldn't be sent without the -f switch.

Maybe we missed something in our settings for this?

I'm thinking not...

Blaming PHP is not reasonable in this case.

Sendmail has to be told what SMTP envelope sender to use if you want it
to use something other than the unqualified local name of the user
running it.


> Maybe we missed something in our settings for this?

Probably.

Look at the 'from=' log line with the same sendmail queue ID. That will
show ayou the SMTP envelope sender, which is distinct from the sender
address(es) in message headers.
