Sounds like the SMTP server won't let you specify a "FROM" belonging to a different domain. If the SMTP server is
smtp.foo.com, it looks like you'll have to beusername@foo.comand notusername@bar.com. /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com -

Sorry, I may have misled you by my earlier reply. The 571 error code can also be returned when the FROM domain doesn't match that of the SMTP server. This is configurable by the ISP. Getting back to your problem: try the issuing the RCPT command without relaying information - i.e. use a direct destination of the form
user@foo.cominstead of@host.com:user@foo.com(which requests thathost.comrelays the mail touser@foo.com). Does this help? /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com -

This is definitely an anti-spam measure. Many SMTP servers are now configured to avoid relaying email from unknown sources to avoid spam and malicious attacks. The SMTP may server may allow you to log in with a valid account, in which case it would then permit relaying. Failing that it probably expects the email to originate within its own domain, try setting the reply address to a user on the same domain as the SMTP server.

If the SMTP server resides with an ISP I would ensure you are connecting to their network via that ISP rather an another ISP. You must use the SMTP server of the ISP you are actually connected with, thus even for somecompany.com you may have to use smtp.btopenworld.com if you connect via BT openworld for example. If the SMTP server resides within a corporate network, check you are sending the email from within that network. Short of that I would contact the administrator of the server for help. You may need to login to SMTP server via secure sockets (STARTTLS) or whatever to actually be granted permission to send email. Otherwise I would try to locate an alternate SMTP which supports relaying. -- The Obliterator
