Hi,

 

I recently set up ACC within an AWS ec2 instance. Also set up postfix on this which is working. However, when creating a delivery within the ACC console the email delivery is showing as sent but is never received. The relay I set up seems to be working as I am seeing the successful connection within maillog, mta logs and mta child logs. From searching the only clue I have at the moment is the following error in my mta child log: 

 

 

2020-05-01 18:26:31.603Z	00000FC4	00000FC4	  1	info	log	Starting an MTA child (pid=4036, tid=4036)...
2020-05-01 18:26:35.761Z	00000FC4	00000FC4	  1	info	log	MTA-740014 '<removed email>' sent
2020-05-01 18:26:41.720Z	00000FC4	00000FC4	  1	error	log	IOB-090007 Network error (recv(), errno=2: No such file or directory) (iRc=-61)
2020-05-01 18:28:02.725Z	00000FC4	00000FC4	  1	info	log	MTA-740013 Message(s) waiting: 0, active session(s): 0.
2020-05-01 18:28:02.725Z	00000FC4	00000FC4	  1	info	log	Stopping MTA child (pid=4036, tid=4036)...

 

 

 I've searched around and can't seem to find solutions by going through my config files or anything online. I can provide more info on my config files if needed.

 

Any help would be appreciated, thanks!

Hello Liam,

 

The log 

log	MTA-740014 '<removedemail>' sent

indicate that the message has been sent successfully assuming this is the email you sent the email to.

Now there are in broad 2 reasons for an email not reaching the user.

 

1. Landing in spam / junk folder - have you ruled this out that the email is not in spam

2. Can be blocked by ISP/ Mail provider / Spam filters - If this is an internal org domain try with a public domain like gmail.com or hotmail.com and if you get the email on them , check with IT to see if communications from the relay server are getting blocked.
