Hi MacPorts Users.
I have a Mac mini running OS X Yosemite and I'm attempting to follow these instructions: https://trac.macports.org/wiki/howto/SetupDovecot I have a problem here: Step 2: create directories When I enter the following at the command line: sudo chown _dovecot:_dovecot /opt/local/var/log/dovecot OS X responds with the following: chown: _dovecot: illegal group name Previous command line code entered, from here: https://trac.macports.org/attachment/wiki/howto/SetupDovecot/Make_Dovecot_Us er.command: sudo dscl . -create /Groups/_dovecot sudo dscl . -create /Groups/_dovecot UniqueID 30 sudo dscl . -create /Users/_dovecot sudo dscl . -create /Users/_dovecot UserShell /bin/false sudo dscl . -create /Users/_dovecot RealName "Dovecot IMAP Server" sudo dscl . -create /Users/_dovecot UniqueID 30 sudo dscl . -create /Users/_dovecot PrimaryGroupID 30 sudo dscl . -create /Users/_dovecot NFSHomeDirectory /opt/local/var/run/dovecot Notes: The _dovecot Group isn't assigned a PrimaryGroupID, but instead a UniqueID. A PrimaryGroupID of 30 is assigned to the _dovecot User. When I view a list of all Groups via the following command: dscl . readall /groups I see a PrimaryGroupID of 30 has already been assigned to _keytabusers. I'm unsure what to do; the following are potential options: Assign the Group _dovecot a PrimaryGroupID; this may prevent the 'chown: _dovecot: illegal group name' OS X response. Assign a different PrimaryGroupID, i.e. other than 30, to both User and Group to avoid the potential conflict with _keytabusers. There may have already been a _dovecot User or Group in the 200 range that I deleted as a result of my confusion. Perhaps this was assigned during the earlier 'Install dovecot' command, i.e. 'port install dovecot'. Do you know what the original PrimaryGroupID of such a User or Group was? If a different PrimaryGroupID is used, i.e. other than 30, presumably the one I deleted would be best. Another option is to upgrade to OS X El Capitan, although I'm not sure whether that will remove the dovecot install thereby allowing me to start again. I'm also unsure whether I could run the 'port install dovecot' command a second time in OS X Yosemite to restore the _dovecot User / Group. Alternatively, perhaps 'port uninstall dovecot' is a valid command to allow me to start again. I've seen reference to dovecot2 in the macports-users archives; perhaps this requires a different syntax, i.e. not 'port install dovecot'. Thanks and best regards, Karl.
