Sep 25, 2017 - sender verify fail for [email protected]: The mail server could not. Then it's because the external server failed to pass the sender verification. Alt-N Technologies Discussion Groups. Based on the log snippet provided, it looks like the message is being routed to an external host and the external host is saying [email protected] does not exist. If you have domain.com setup as a local domain, then MDaemon should be keeping all email for any mailbox @domain.com locally, unless you have configured something to instruct it to route it.

affirmative i did changé those to exampIe.com in purchase to post here
Possess you thought out what the concern has been? I'm up against as very similar error information: '550-Sender offers no A new, AAAA, or MX DNS records. WordPress-on-1404.xxxxxx-xxx 550 WordPress-on-1404.xxxxxx-xxx (in remedy to RCPT TO command word)' and waiting around for my assistance solution to end up being clarified.
Email sent from a daémon on my server linking to exim4 daemon light using SMTP appears to be being frozen. In the exim4 sign:
I think this is definitely stating exim4 rejected the sender's i9000, i.y. the from e-mail deal with? Exim4 is certainly operating on server.illustration.com and I have always been making use of [email protected] as thé sender which will not can be found - it worked well in the last. I acquired to recently re-do domain records on example.com but they are usually all OK now and have percolated out (they were done times ago).
I believe I have got the same issue as here: http://help.diréctadmin.com/itém.php?id=59, but cannot consider the option as cannot discover exim4 configuration file is - there are usually numerous under/étc/exim4/conf.n
(I just randpkg-reconfigure éxim4-configwhén I installed exim) and the records says there is definitely simply one? Also how had been it functioning just before?I have always been prepared to enable any sender - the firewall obstructions external access to exim and I was only making use of it to send out email from my own daemon.
UPDATETransmitting to additional email tackles works, just to particular one particular (that is certainly legitimate) does not - which will be strange because exim states it is issue with sender not really receiver?!

lt is usually the receiving MTA that is rejecting the nón-existent sender; thére can be nothing that you can do about that on your finish about that (besides simply using a real sender).
I also reject cover senders that do not can be found, as that means that NDRs furthermore can't become delivered to the sénder, and in 99.5% of the cases a non-existent cover sender is junk mail or phishing or related. There's no great reason not to use a operating package sénder.

Examine for a 'verify = sender' in your Exim acl't, like as the oné that executes fór the RCPT T0: command word (look for acIsmtprcpt=xxxxx). Thát Exim choice in an acl bank checks to make sure the sender is a 'legitimate' (notice exim documents for precisely what that means), and you may need to eliminate it since this is certainly an internal server just delivering from false senders. In a creation machine, there are usually better ways to perform the exact same.
lf your acl's are examining the sender when digesting the RCPT T0:, like some constructions do, then you can obtain this message where it appears like the problem is certainly in the recipient when it can be in fact the sender verify causing the being rejected.
Test working a command-Iine exim in deal with verification mode to observe which acl'h are doing:
