Created attachment 1510 [details] Claws Mail screen showing four accounts (3 IMAP, 1 POP3, at lower right of window) and no Mailbox MH folders shown. This was originally reported to Fedora at https://bugzilla.redhat.com/show_bug.cgi?id=1225676 but I think this should have been reported here. With Fedora (21), the MATE desktop installs Claws Mail as the default e-mail program. I discovered that when adding an IMAP account first, to a new installation, then adding a POP3 account afterwards, the Mailbox (MH) folders do not appear in the folder tree. If the POP3 account is added first, before any other account, MH appears correctly. I am attaching screenshots showing what happens when IMAP is added first, then POP3 and also with no IMAP accounts and POP3 added first. clawsscreen1.png Shows the three IMAP accounts on the left, account1, account2 and account3. At the lower right corner of the screen, the account list also has account4, this is the POP3 account. clawsscreen2.png) shows the screen after the steps outlined in the above Fedora bug report were taken and only the POP3 account was added. "Mailbox (MH)" was then successfully created.

It's entirely possible that the user would want to get his mail from the POP server and have it stored on the IMAP server. The user can create an MH mailbox if he/she wants one, so I'm 'downgrading' this to 'enhancement', as perhaps the user should be prompted (via a dialogue) to create an MH mailbox if one does not exist.
