iRedAdmin-Pro: Domain ownership verification

Summary

Since iRedAdmin-Pro-SQL-2.5.0 and iRedAdmin-Pro-LDAP-2.7.0, it's able to grant normal domain admin permission to create new mail domains. All new domains added by normal domain admin require domain ownership verification by deafult, to ensure:

• the newly added mail domain name is a valid domain name on internet
• the domain admin have the required privileges in the domain to manage the email services

Mail services are disabled for pending domains, and will be activated automatically after admin verified the ownership.

How to enable or disable domain ownership verification

There're few parameters used to control domain ownership verifivation, you can find default settings in file libs/default_settings.py under iRedAdmin-Pro directory. If you want to change any of them, please copy the parameter to iRedAdmin-Pro config file settings.py, set proper value, then restart Apache or uwsgi (if you're running Nginx) service to reload the changes.

# Require domain ownership verification if it's added by normal domain admin:
# True, False.
REQUIRE_DOMAIN_OWNERSHIP_VERIFICATION = True

# How long should we remove verified or (inactive) unverified domain ownerships.
#
# iRedAdmin-Pro stores verified ownership in SQL database, if (same) admin
# removed the domain and re-adds it, no verification required.
#
# Admin won't frequently remove and re-add same domain name, so it's ok to
# remove saved ownership after X days.
DOMAIN_OWNERSHIP_EXPIRE_DAYS = 30

# The string prefixed to verify code. Must be shorter than than 60 characters.
DOMAIN_OWNERSHIP_VERIFY_CODE_PREFIX = 'iredmail-domain-verification-'

# Timeout (in seconds) while performing each verification.
DOMAIN_OWNERSHIP_VERIFY_TIMEOUT = 10

How to verify domain ownership

There're several ways to verify domain ownership:

• Create a text file under top directory of the web site of new domain, both file name and file content must be same as verify code.

  For example, for pending domain example.com with verify code iredmail-domain-verification-5tzh5gHjU688yyWK7cSV, iRedAdmin-Pro will verify 2 URLs:

  • http: http://example.com/iredmail-domain-verification-5tzh5gHjU688yyWK7cSV
  • https: https://example.com/iredmail-domain-verification-5tzh5gHjU688yyWK7cSV

  If you visit the URL with a web browser, it's expected to display verify code as page content.

• Create a TXT type DNS record of the domain name, use the verify code as its value.

  For example, for pending domain example.com with verify code iredmail-domain-verification-5tzh5gHjU688yyWK7cSV, DNS query by command nslookup -type=txt example.com should return a record which is same as verify code.

Sample DNS query with nslookup:

$ nslookup -type=txt example.com
...
example.com     text = "iredmail-domain-verification-5tzh5gHjU688yyWK7cSV"
...

Sample DNS query with dig:

$ dig -t txt example.com
...
iredmail.org.       4173    IN  TXT "iredmail-domain-verification-5tzh5gHjU688yyWK7cSV"
...
