I don't know what dovenull user is or why it is necessary. It would be a lot smoother (and this probably applies to all other software you use) if you would spend at least 5 SECONDS doing a little research before wasting everyone's (especially Timo's) time with questions that you can easily answer yourself: http://www.lmgtfy.com/?q=dovenull For dovecot stuff, I've found that simply adding the word 'wiki' after the other search term will almost always provide the link to the wiki page describing whatever it is: http://www.lmgtfy.com/?q=dovenull+wiki Yes, this is a pet peeve of mine... -- Best regards, Charles

And some may be building binaries packages for distribution so forcing user creation on a build server would be extra unhelpful work. On thing I was considering was if patching to allow configure to set -- default_login_user=_dovenull and --default_internal_user=_dovecot. I don't think this is a big deal but it would allow package builders to build packages with default names that match their distributions. BTW, things are fine the way they are. The fewer options that meet the needs the better. Regards, Bradley Giesbrecht

The only things I'm going to change here is to make the error message somewhat better for v2.0.1 and add a note about this user to NEWS file / release announcement.

See Timo's comment of Friday 13/08/2010 19:29: http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc6.tar.gz.sig I expect this to be the last release candidate. Unless release critical bugs are reported, I'll update the version number to v2.0.0 on Monday morning without any other changes. Since rc5 there have been mainly some small fixes and some error message improvements. The only (somewhat) important fixes are: - dict quota didn't always decrease quota when messages were expunged - Shared INBOX wasn't always listed with FS layout I'll update the version number to v2.0.0 on Monday morning Bill
