I have a perplexing puzzle thrust upon me. Consider the following:
Oct 8 15:55:33 minbar postfix/smtpd[7422]: NOQUEUE: reject: RCPT from rs230.mailgun.us[209.61.151.230]: 551 5.1.8 <[email protected]>: Sender address rejected: Domain not found; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<rs230.mailgun.us> mailgun.us is connecting with a good HELO, and appears to be authorized to send mail on behalf of pluspora.com, but the mail has a sender address that is bad because mg.pluspora.com does not resolve in DNS, and so the mail is rejected. I want to TEMPORARILY (I hope) whitelist [email protected] as a sender address as long as the mail is being sent by mailgun.us. How would you do it? -- Phil Stracchino Babylon Communications [email protected] [email protected] Landline: +1.603.293.8485 Mobile: +1.603.998.6958
