Version: 0.5.0 (using 3.5.10, Gentoo) Compiler: Target: i686-pc-linux-gnu OS: Linux (i686) release 2.6.28-tuxonice-r3 Folders with names like host\.domain\.tld.INBOX are displayed as subfolder chain host->domain->tld->INBOX It should be just one subfolder host.domain.tld->INBOX as e.g. thunderbird gets it correctly. In the folder names dots _not_ separating folder hierarchy are escaped by \ on disk and served by bincimap.
Folder.host\.domain\.tld.subfolder is treated correctly as Folder->host.domain.tld->subfolder BTW
I guess you are looking at mailody4 with the imap akonadi resource. If this is correct, there is good news. the imap akonadi resource is currently be rewritten by professionals, so this should be fixed in kde 4.3.0 if they manage to finish it in time. Closing it as fixed for now.
