Hello, Having a grave problem with recently compiled Exim 4.90.1 (running on Ubuntu 16.04 64bit).
Primary domain: example.com In /etc/aliases: user: [email protected],[email protected] When I run command like exim -bt [email protected] Exim prints correct MX records for every particular address the above recipient forwards mail to. However, when I try actually send message to the above, I see something like below in main.log: 2018-03-19 20:46:59 1exv5t-0003k7-NV ** [email protected] <[email protected]> R=dnslookup T=remote_smtp H=example.net [69.73.xx.xx] X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no: SMTP error from remote mail server after RCPT TO:<[email protected]>: 550-Please turn on SMTP Authentication in your mail client.\n550-mail.example.com (mail2016.example.com) [52.45.xx.xx]:49156\n550 is not permitted to relay through this server without authentication. (attempts to send mail to A records instead of any of MX) DNS lookup router is pretty much standard: dnslookup: driver = dnslookup domains = ! +local_domains transport = remote_smtp ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 no_more The host in A record doesn't process incoming mail for the domain in question (in the above sample, example.net), thus delivery fails. The above doesn't happen if I use Exim 4.87, and happens quite often if I use 4.90.1 Is it a known issue? DNS resolver works without problem, I checked that before sending yet another mail that failed in the above manner. I would appreciate pieces of advice on how to handle this. Thank you.
