Splitting up packages

I'm the maintainer of the dovecot and pigeonhole ports on FreeBSD and am looking to make separate installable packages like the project does for Linux. Can you help me know what needs to go where and what options (if any) change the base? Thanks for any help here. -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 (c) E-Mail: larryrtx(a)gmail.com US Mail: 5708 Sabbia Dr, Round Rock, TX 78665-2106 I'm the maintainer of the dovecot and pigeonhole ports on FreeBSD and am looking to make separate installable packages like the project does for Linux.

We couldn't drop root group privileges

Hello. I have - dovecot 2.3.21 (also tried 2.3.5) - postfix 3.8.5 (also tried 3.8.4) It's a new setup where I use postfix + dovecot-delivery for delivery to local mailbox. At logs I have an error and mail deffers in queue: dovecot: [ID 702911 mail.crit] lda(poli(a)domain.com)<7808>: Fatal: We couldn't drop root group privileges (wanted=6(mail), gid=0(root), egid=0(root)) Postfix and dovecot start from root UID, but user dovecot/postfix has corresponding groups to run as specific group: root@solaris:# id -a dovecot uid=110(dovecot) gid=110(dovecot) groups=110(dovecot),6(mail) root@solaris:# id -a postfix uid=26(postfix) gid=26(postfix) groups=26(postfix),6(mail) root@solaris:# id -a root uid=0(root) gid=0(root) groups=0(root),1(other),2(bin),3(sys),4(adm),6(mail),7(tty),8(lp),12(daemon) Also, when I run a dtrace (a system call trace mechanism) I see, that dovecot-lda runs as group "mail" (gid=6), so, there isn't any problem, but dovecot thinks another: UID GID PID PPID ARGS 0 26 7719 7638 pipe -n dovecot -t unix flags=DRhu user=nobody:mail argv=/usr/libexec/dovecot/d 60001 6 7720 7718 /usr/libexec/dovecot/dovecot-lda -f mega(a)domain.com -d poli(a)domain.com 60001 6 7720 7718 /usr/bin/amd64/doveconf -f service=lda -c /etc/dovecot/dovecot.conf -m lda -e / 60001 6 7720 7718 /usr/libexec/dovecot/dovecot-lda -f mega(a)domain.com -d poli(a)domain.com What exactly dovecot wants and how to solve this error? Here is part of "dovecot -n" output which is corresponding to user/group/lda: # 2.3.5.1 (7ec6d0ade): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.6 (92dc263a) # OS: SunOS 5.11 i86pc # Hostname: solaris auth_debug = yes auth_mechanisms = plain login auth_verbose = yes default_process_limit = 99 disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 60001 last_valid_gid = 6 last_valid_uid = 60001 mail_access_groups = mail mail_debug = yes mail_gid = 6 mail_location = /var/mail/vmail/%u@%d mail_max_userip_connections = 99 mail_privileged_group = mail mail_uid = 60001 maildir_very_dirty_syncs = yes ... service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ... protocol lda { mail_plugins = " sieve" postmaster_address = postmaster } PS. Also, I have aother box with very old setup (dovecot 2.2.27) and it works with the same configuration without any errors. I thought that this is OS specific problem and tried on the same version OS run a dovecot 2.3.21, but still had an errors.

Emails automatically thread by subject, no matter how old or unrelated

To preface, I’m using the Crossbox mail client hosted by MXroute. I was directed to Dovecot support when I made my inquiry to the former’s developers. Apparently, when you write an email subject that is verbatim to another, previously sent email, the two become linked in a conversation thread. I could have an email from 1996 titled “Groceries” and if I make one today titled “Groceries” my inbox would have them connected as one long thread. I’m getting email threads in the 100s because of this. Crossbox people have told me it’s not something they have control over. They mentioned it being a Dovecot problem. Has anyone encountered this? It would be tremendously inconvenient to ensure that every email I ever send from now on has a unique subject so to as not have them threaded together. Let me be clear, email threading and conversation views are extremely useful. I just want them to be…relevant to the chain of emails that are being looked at. Is there a way to group threads by unique header information? It is becoming borderline unusable to sift through invoices.
