Hi,

When disabling greylisting for a particular domain through iRedAdmin-Pro-SQL-4.1.2 there are not any rules created for alias domains.

Is this a feature that could be added or am I missing something that iRedmail does in the background for this? I realised this after a report of slow email delivery and found that the emails had infact been greylisted even though we thought it had been disabled in iRedAdmin.

I have since used the tools/greylisting_admin.py to disable greylisting for the alias domains.

Many thanks,
Nick

Re: Greylisting for alias domains in iRedAdmin-Pro

Seems a bug of the iRedAPD greylisting plugin, i will check and fix it later.

Created an issue to help track this bug:

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
