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 <redac...@mg.pluspora.com>: Sender address rejected: Domain not found; from=<bounce+db1162.5fcd4c-alrekr=caerllewys....@mg.pluspora.com> to=<alr...@caerllewys.net> 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 redac...@mg.pluspora.com as a sender address as long as the mail is being sent by mailgun.us. How would you do it? -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958
