After many years with only one mailbox shared by multiple email accounts, I added a new mailbox for testing/internal use, and moved it to the top in order. New mail began to appear in its Inbox. Discovered that several of my 14+ year old accounts only had "inbox" in the Default inbox field. Changed all accounts to point to full path (#mh/Mailbox/inbox) of the original to resolve. Any account containing should be converted to fully-qualified to avoid accidental delivery to the wrong mailbox after mailbox maintenance.
#mh/Mailbox/inbox is the default value for a POP account's Inbox, and there is no way to automatically determine which MH mailbox a POP account should use.
Created attachment 1686 [details] not FQ inbox... It may be the default currently; but that was not always the case. This is a screen shot of one account on my other instance of CM which only has one MH. I filed this as an enhancement because it is a timebomb; though a very unlikely one for most users. No objection to closing as invalid; but maybe a new section in the release notes would be useful... like this: Issues which may be present; but will not be fixed since only older installations may be affected. Recent installations should not exhibit these issues. * Users with a single MH mailbox should check their account settings' Default inbox on the Receive tab. It should contain a fully qualified box name (e.g., #mh/Mailbox/inbox). Older versions of claws-mail used 'inbox' which could cause problems if a new mailbox is added. Click the Browse button, select Inbox, OK, Apply.
