Hi list,

it's been 2 months now since my initial posting (s.b.). I wonder if I could get at least a "still working on it" statement from the devs or something like that?

We have plans to make the lda-dupes database a dict. In that case there's much more flexibility to make this work across replication.

Regards,

Stephan.

Hi list,

this question was already posted a few years ago (https://www.dovecot.org/list/dovecot/2014-November/098585.html). I already asked the original queriest and he told me, that he never got an solution or workaround but it was not important enough for him.

When using replication in conjunction with sieve vacations, the .dovecot.lda-dupes file is not synced with the other server. So when delivering to both servers (round-robin or randomized), senders might get more vacation mails than configured as the other server does not know, that the first one already sent a vacation message.

Is this a bug or intentional? If it is a bug, I hereby ask for a fix, please.

We are using Dovecot version 2.2.27 on Debian/stretch. This is dovecot -n (hostnames anonymized):

And this is /etc/dovecot/ldap.conf (hostnames anonymized):

uris = ldaps://ldap1/ ldaps://ldap2/ base = dc=domain user_filter = (&(objectClass=posixAccount)(uid=%u)) user_attrs =
=user=%{ldap:uid},
=uid=%{ldap:uidNumber},
=gid=%{ldap:gidNumber} pass_filter = (&(objectClass=posixAccount)(uid=%u)) iterate_filter = (&(objectClass=posixAccount)(istMailHomeServer=servername)) auth_bind = yes

/etc/dovecot/userdb.override is currently an empty file.

P.S.: Although I do not think, that this has something to do with our problem, I should mention that we run SIS with system uids. This needs some permission and posixacl tweaks on /IMAP/mail/attachments to work:

# force all files created in this dir recursively) to have mode 0666 setfacl -d -m group::rwx -m o:rwx /IMAP/mail/attachments (you have to enable posixacls for the corresponding filesystem!)

# trick dovecot to inherit parent dir's permissions (recursively) chmod 2777 /IMAP/mail/attachments

Feel free to add these tweaks to the SIS documentation. ;-)

Best Regards,
