Check this out: toaster# telnet legend.co.uk 25 Trying 212.69.224.224... Connected to legend.co.uk. Escape character is '^]'. 220 www.legend.co.uk ESMTP Postfix (Release-20010228) (Linux-Mandrake) MAIL FROM:<[EMAIL PROTECTED]> 250 Ok RCPT TO:<[EMAIL PROTECTED]> 554 <[EMAIL PROTECTED]>: Recipient address rejected: Relay access denied quit 221 Bye Connection closed by foreign host. That's a 554 from legend.co.uk for an attempt to send mail to [EMAIL PROTECTED] HOEWEVER, something odd is happening, because... toaster# host legend.co.uk legend.co.uk has address 212.69.224.224 legend.co.uk mail is handled (pri=20) by mx.legend.co.uk toaster# host mx.legend.co.uk mx.legend.co.uk has address 212.69.225.52 toaster# telnet 212.69.225.52 25 Trying 212.69.225.52...

So legend.co.uk is a machine that doesn't handle mail for addresses @legend.co.uk. The machine mx.legend.co.uk DOES, and it doesn't seem to mind accepting mail for [EMAIL PROTECTED] >-----end quote----- >Now, my reading of a "554" is that somewhere, a server thinks I'm >relaying.

No. The unanswered question is why SIMS was trying to use the A record for legend.co.uk and not the MX record. Using the A record, you get a machine that seems willing to accept mail for [EMAIL PROTECTED] The SIMS logs might provide a hint as to why it fell back to using the A record. That is something it should not do, even if the address of the MX record is inaccessible. If there is an MX record but that machine can't be reached, the A record should not be treated as a potential mail exchanger. That strikes me as a SIMS bug, most likely. Of course this does not solve your problem: you seem incapable of contacting 212.69.225.52 from your SIMS machine.
