I'm sorry, I should have read more! I'll have an actual look at the code now :) I can tell you right away that removing stuff from the ENUM is going to break unless you also remove every use of the ENUM items. You want to search for this in imap/mboxlist.c: mboxlist_findall (it's line 1926 in 2.4.10) if(!r) { >-------cbrock.find_namespace = NAMESPACE_USER; >-------/* switch to pattern with domain prepended */ And change it to if(0) { or just delete that block of code. I wonder if we should just not do that lookup if foolstupidclients is on. Feel free to file a bug if you want, and ask around on the mailing list. I'd be happy to change foolstupidclients to do this, or add another option if there are any foolstupidclients users who care about it.
