smtp error

[Ariën Huisken]

Hi list,

I try to send an email messages to someone, but I get the following error:

<***@example.com>: host mail.example.com[11.11.11.11] said: 550 5.7.1 Phrase
in email not acceptable (in reply to end of DATA command)

Does anyone know what this error means?

Thanks,

Arien

Hi,

sounds like some spam filter is checking the content directly in the
smtp session and is rejecting the mail because it thinks it is spam.
I have ASSP running as spam filter and it does it this way too.

best regards,

Well, its rejecting all my messages on this server, no matter what the
content or the used client over here is. Used my hotmail account and
it accepted my mail.

Thanks.

Then something that gets inserted by the server must be blacklisted..
hostname in recieved-by headers?

I have no idea, never seen this before.

This could be the case if the receiving server does its checks on all
data or the mime headers instead of only the body.

One could easily do this kind of "mistake" in Postfix for instance, by
listing spam dictionary checks with the "header_checks" directive,
instead of using the "body_checks" directive.

Then again, I too would probably blacklist client hosts with *porn* in
their hostname :)

Could be the case. I contacted the sysadmin of this server through my
hotmail account.. :)

Or not :D

I guess example.com is employing a simple content filter as:

*porn* REJECT

in their sendmail.

550 5.7.1 Access denied

HELO is valid and has also a reversed DNS record with the same name,
so that should not be the problem.

Maybe your provider is filtering all your outgoing smtp-traffic on port
25 like AOL does with a smtp-proxy?
Try to do an simple smtp-dialog on the command-line, using telnet. What
is happening?

No, this server is sending many emails for hundreds of users, only
happens when sending to this host.
The connection not filtered on any port.
