Hi, we have the UUCP connection to the world. And some time ago I've notice that some e-mail addresses cannot be reached from us. I guess I know what's happening, but completely don't know is it someone's fault. I think that somes sites are checking for a validity of sender's domain - for example, to prevent spamming in such a way. We have no usual domain, but UUCP-domain surely exists... Trying to send a mail to address skazak@glasnet.ru I received the following: ... > from uucp@creator.gu.kiev.ua [194.93.190.3] > > ----- The following addresses had permanent fatal errors ----- > <skazak@glasnet.ru> > > ----- Transcript of session follows ----- > ... while talking to mx.glas.apc.org.: > >>> MAIL From:<@vicotec.UUCP:yura@vicotec.kiev.ua> SIZE=292 BODY=8BITMIME > <<< 550 '<@vicotec.UUCP:yura@vicotec.kiev.ua>SIZE=292 BODY=8BITMIME' sender address is not a valid domain. > 554 <skazak@glasnet.ru>... Service unavailable > [ Part 2: "Included Message" ] Final-Recipient: RFC822; skazak@glasnet.ru Action: failed Status: 5.0.0 Remote-MTA: DNS; mx.glas.apc.org Diagnostic-Code: SMTP; 550 '<@vicotec.UUCP:yura@vicotec.kiev.ua>SIZE=292 BODY=8BITMIME' sender address is not a valid domain. Last-Attempt-Date: Tue, 28 Oct 1997 13:38:06 +0200 [ Part 3: "Included Message" ] Date: Tue, 28 Oct 1997 13:13:35 +0200 From: Yury Dudnichenko <yura@vicotec.kiev.ua> To: skazak@glasnet.ru .... My ISP's gurus are gone to conference for few days and no one there can't tell me whose this bug... Is it a bug at all? Is there a way to resolve this situation? Funny thing, but I can't send mail to Postmaster@glas.apc.org for the same reason. And, surely, don't know his phone number to call him directly.
