XMail defines a mail loop as a message with more than (by default 16) Received: headers. It counts these headers and does not try to detect if a message is really going back and forth. The (good) assumption is that, if there are too many Received: then something is wrong somewhere, whether a loop or not (and a loop will always generate too many Received: sooner or later ...). Now, suppose Ecartis adds, say, 9 Received: headers. If a message is re-injected, it gets another 9 Received: headers prepended to it, so that XMail sees too many Received: and declares a mail loop. The actual number of Received: headers may vary, so a re-injected msg may get through on a system and be declared a mail loop on another. Anyway, the 'loop' is the sheer number of Received: which in this case depends on re-injection rather than a 'loop' proper. But the above assumption is still good :-) Ciao, Francesco - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]
