The "return path not verifiable" usually means that the receiving server is trying to check that the claimed sender's address is a genuine mail account. Typically it does this by starting a "send mail" transaction to the address named in the MAIL FROM command, but aborting it before actually sending anything. If this attempt fails, it concludes that the send in the MAIL FROM command is a fake. In this case, though, it appears to be checking the _recipient's_ address (robert.wolfe@winserver.us), and discovering that winserver.us will not accept mail for robert.wolfe. This does not make sense. It should be checking the sender's address. Maybe we need to see a longer section of the log to work this out. (Meanwhile, someone else on the list might have a better idea. I see that Steven suspects an SPF problem.) I seem to recall trying to reply to mail from Robert Wolfe, and not being able to get through. I've just sent a test message, but haven't yet had a response from the (presumably rejecting) server. It might help if I could get a look at the WEASEL.INI or WEASEL.TNI file, as appropriate. -- Peter Moylan peter@pmoylan.org http://www.pmoylan.org -- This email was Anti Virus checked by Astaro Security Gateway. http://www.astaro.com ----------- To unsubscribe yourself from this list, send the following message to MajorMajor@os2voice.org unsubscribe weasel-list end -- This email was Anti Virus checked by Astaro Security Gateway. http://www.astaro.com * Origin: (1:3634/12) .
