Re: dying on osx

I found and tried this work around on the man page: https://www.unix.com/man-page/all/5/ngroups_max/ but I still get the same "Too many extra groups" error even when I start dovecot with the above program to limit the # of groups. I suspect that dovecot is adding a number of groups when it starts up. I've hacked a work around to get it working for me on my laptop: diff --git a/src/lib/restrict-access.c b/src/lib/restrict-access.c @@ -224,7 +224,12 @@ static void fix_groups_list(const struct restrict_access_settings *set, -    if (setgroups(gid_count, gid_list) < 0) { +    if (setgroups(gid_count > NGROUPS_MAX ? 16 : gid_count, gid_list) < 0) {          if (errno == EINVAL) {              i_fatal("setgroups(%s) failed: Too many extra groups",                  set->extra_groups == NULL ? "" : and this works. I'm not sure what the right solution is for a PR. Any suggestions? Thanks Mike On 8/10/18 11:04, Aki Tuomi wrote:

I did find that page and tried a few things there. My config has all of the settings there except 3:

mail_access_groups = mail mbox_read_locks = fcntl mbox_write_locks = fcntl

I add them to my config, restart and get the same abort

20180810-103849 imap(mkm)<79213>: Fatal: setgroups(mail,505) failed: Too many extra groups

I've tried numerous other settings as well.

Thanks for any further advice

OSX 10.13.6 High Sierra, dovecot 2.3.2.1

dovecot starts up and runs but dies as soon as my mail client makes a request with log and config below.

And advice appreciated.

Thanks
