How to disable automatic IMAP acct creation ?

[asyncnomi]

Hello,

I have some emails address that only need to send mail and should not be able to receive any.
Those specific mail shouldn't have IMAP storage.
(those are used for other self host services like forgejo or vaultwarden)

The thing is maddy is automatically creating the IMAP storage on IMAP login, so as long as I don't make any IMAP login to those it's fine. But that something that can really easily be made by mistakes. And one login is sufficient to cause storage nightmare for those highly uses address.

IMAP acc creation for mailboxes that need one is already handle by a custom script (to ensure creation before the first login), so I don't need that feature.

Is there an option to specifically disable this behaviour ?

Thanks for the help :)

PS: The auth nighmare is due to the use of multiple auth backend (including localdb) at once (with specific policy between them)

I ended up blocking imap auth for those account using another external auth script
