iRedMail → iRedMail Support → Catch-all address for a domain + all subdomains
Hi,
Is there a way to configure iRedmail to accept all emails sent to "*.example.com"?

Am aware that this catch-all if for *@example.com - but that is not my usecase here.
*@example.com/*@*.example.com is a more accurate description.
if a subdomain is not added as maildomin in the virtual table, then mail will get rejected unless it is a virtual forwarding, you can only use regex in this case then

Yes, I am aware that the email will be rejected.
But are you saying that iRedmail is capable of regexes like this?
([a-z0-9](?:[a-z0-9-]{1,61}[a-z0-9])?[.])*sub[12][.]example[.]com
So if I just add the catch all like the docs described, but instead uses the regex - that would work according to you?
more like:
(^|.+\.)domain\.tld$
but be aware, that only works if that subdomain has an MX entry aswell
OR
you add a wildcard MX entry, but this will open huge space for dictionary attacks and be aware that you will get a shitton of spam
more like:
(^|.+\.)domain\.tld$
Thanks, I'll try that.
Also, I am fully aware of the rest. But recieving spam is what I want to achieve with this

*@example.com/*@*.example.com is a more accurate description.
Would you mind sharing why you need to support such addresses?

Honeypot basically.
A very edge-case

Appreciate the reply!
I added the following:
INSERT INTO forwardings (address, forwarding, domain, dest_domain) VALUES ('(^|.+\.)domain\.tld$', 'catch-all@domain.tld', '(^|.+\.)domain\.tld$', '(^|.+\.)domain\.tld$');As that is how I understand how it should be in this case, right?
I am getting "relay access denied", I suppose I also need to change something in iredapd to be able to relay emails from *.domain.tld to the catch-all address?
Thanks!
this does not work with sql, needs to be implemented as virtual mailbox in postfix
