catch-all behavior related to ANONADDY_ALL_DOMAINS

Description

Not sure if I found a bug or a feature

It seems, catch-all not always works, when I would expect.

However, to me it seems contrary to the description, which says:
ANONADDY_ALL_DOMAINS: If you would like to have other domains to use (e.g. @username.example2.com), set a comma separated list like so, example.com,example2.com (default $ANONADDY_DOMAIN)
Based on this I expected, I will need to have all domains used in this line

Expected behaviour

• I'm self-hosting anonaddy, using most recent version, 0.14.1
• I have the main domain + additional 2 domains: catch-all is activated on both additional domains

Actual behaviour

• I've recently added the 2nd additional domain, and noticed that catch-all was not working (and not even on the first one)
• I've recently changed to this setting:
  ANONADDY_ALL_DOMAINS=mainaddydomain.com,domain2.com,domain3.xyz

=> in these cases only addresses already created manually would work and be forwarded.

Additional problem, that there is no feedback at all about not forwarding the mail (it just goes into nowhere). The server does receive the message from the external sender (smtpd), but does not forward it to the recipient (smtp)

Steps to reproduce

In the anonaddy.env:

Catch-all not working
ANONADDY_ALL_DOMAINS=mainaddydomain.com,domain2.com,domain3.xyz

When I remove the 2 additional domains from this line, catch-all seems to work again
Catch-all is working:
ANONADDY_ALL_DOMAINS=mainaddydomain.com
