Topic: Client does not recieve mail - checklist

I am looking what is the cause why my client does not recieve email:

I created a checklist, but i would like to know if there is something i missed.

- mxtoolbox
      -> mx check for my domain -> 1 record found
      -> Blacklist check -> all green
      -> Test mail server with mx.domain.com -> all green
      -> Grey listing in turned off for her domain. (And in general also)
- Logging -> no email found from domain
- quarantine -> empty (all default settings)
- veryfy email adres (HELO command) -> result OK

I need some help here ...

I contacted some people, ask them if they recieve error mails ?

Only one responded to me

Re: Client does not recieve mail - checklist

i only recieved this error code:

Do i need to change something as a mail provider ?

Could not be delivered because of

554 5.7.1 <SRV-SECURE.MARMA.local>: Helo command rejected: ACCESS DENIED. Your email was rejected because the sending mail server does not identify itself correctly (.local)

The following recipients were affected:
   xxx@domain.com

Yes. Comment out the line with '\.local' in /etc/postfix/helo_access.pcre, then reload Postfix service.

To be clear: This is NOT your (iRedMail) mistake, but an improper configuration of the sender server. They must use a valid FQDN hostname as HELO identity, and must be available in DNS. Obviously, xxx.local is not an valid DNS top domain.

The fact is we're in an unperfect world, not all mail servers are properly configured by their sys admin, so someone has to compromise.

The better way is: contact the sys admin of sender server, ask them to use a valid HELO identity.

Re: Client does not recieve mail - checklist

And my other question about checks i need to do.

Did i forget someting, it's handy when a problem pops up what i need to check for that domain.

Thanks!
