Topic: iredAdmin-Pro whitelist user fails

==== Required information ====
- iRedMail version (check /etc/iredmail-release):
- Linux/BSD distribution name and version:
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro?
- Related log if you're reporting an issue:
====

CentOS 6.7 with iredmail 0.9.4 & admin-pro 2.3.1 MySQL

Have a user in the field of:
System => Anti-Spam => Whitelist/blaclist. 
  The e-mail address is listed here but continues to be rejected.
   Example:

Feb  3 20:21:47 mail02 postfix/smtpd[31689]: NOQUEUE: reject: RCPT from tld.net[x.x.x.x]: 450 4.1.8 <SHM@uxhpvm21.sub.doman_name.tld>: Sender address rejected: Domain not found; from=<SHM@uxhpvm21.sub.doman_name.tld> to=<user@local_domain.com> proto=ESMTP helo=<host.tld.net>

Obviously domain not found.  However, how is this controlled/corrected since thought the whitelist would bypass this check.

Re: iredAdmin-Pro whitelist user fails

Postfix queries DNS to verify sender domain before calling iRedAPD (for white/blacklisting an more), so whitelisting this sender cannot solve this error.

You can update DNS server to make this domain resolvable, or try to add this domain name in bot /etc/hosts and /var/spool/postfix/etc/hosts.

That seems like a tricky issue to address as lots of operations may write applications without a valid DNS present.  In this case, the actual domain is valid but not the sub-domain, tertiary domain portion. 

So, even this syntax would fail.    @.domain.com

I suspect that there is some method of accepting it ahead of DNS.  Would it be in mynetworks but adding the IP of the application?

You know mail services heavily reliies on dns service.
