Hello,

Most "doveadm" commands accept "[-A|-u user|-F file]" for user selection, or the environment "USER". I'm testing with "doveadm quota recalc".

The problem is that there is no way to ask "doveadm" to work in (1) single-user mode with (2) no wildcard support, and at the same time to (3) make a lookup in "userdb", in order to get the user's specific configuration. We have mailboxes which contain "?" and "*" symbols, and we can't work with them using "doveadm" now.

• If we use "-A", this works with all users. Not our case at all.
• If we use "-F" and provide just one user in the file, this works for a single user + lookup in "userdb", does not interpret wildcard, but "doveadm" works in a "users list" mode and the output is different. What's more problematic is that errors for an mbox do not end up in "doveadm" exiting with a non-zero exit code.
• If we use "-u", this works for a single user + lookup in "userdb", but interprets wildcards. Does not work for mailboxes which contain "?" and "*".
• If we use the USER environment, this works for a single users and does not interpret wildcards but does not do a lookup in "userdb".

Should we add another user-selection argument, for example "-U", which (1) selects a single-user like "-u", does a "userdb" lookup like "-u" does, but does not interpret wildcards unlike "-u" ?

Best regards. --Ivan
