Topic: Specific header for each domain

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release):
- Deployed with iRedMail Easy or the downloadable installer?
- 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?
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====
I have below error in log file:helo cmd rejected:host not found
Sender have multiple domain in a mail server. I think it causes mismatch in hello packet. Is it possible to have specific header for each domain?
When i add that domain in sender_pcre problem was solved.

Re: Specific header for each domain

"host not found" means the domain name used in HELO command is not resolvable by DNS query.
