It is no surprise, though, that the IPv4 address still appears in Samba DNS (can be seen when running 'samba_dnsupdate --verbose'). I am aware of the documentation for changing an

Lightweight LMTP daemon to avoid overkill MTA
I ended up 'hacking' LMTP support into the external spam filter. Someone else already contributed 'real' patches to implement LMTP support, so once I go live with this mail platform it should be stable.

Yes I am running sendmail next to dovecot on backend servers. That works
ok. I have some problems with re-routing mail in a proxy setup.

Hi,
I was unclear in my question. The spam filter is only able to deliver mail over SMTP, not over LMTP.. So I would still need some kind of daemon that listens for SMTP and then offers incoming email to Dovecot's LMTP socket.

Lightweight LMTP daemon to avoid overkill MTA
Hi,
My situation is as follows.
-An internet-facing spam filter relays email to destination mail server (Dovecot) with SMTP.
- Dovecot should take email and deliver it to user's mailboxes. I guess I'd need LMTP for this.
- An external SMTP relay is already in place. I am thinking of using Dovecot submission to relay to the external relaying cluster.
So, both relaying and routing are done

Submission config being ignored
I'm having trouble setting up submission with Dovecot proxy. The submission config seems to be getting ignored, but I'm probably doing something wrong.
Expected behaviour: have messages sent to submission ports (25, 465) relayed to `submission_relay_host`.

Dovecot proxy: authentication best practices
Hi!
I have a few questions regarding Dovecot proxy:
1.
1.1 If I understand correctly, setting 'nopassword' in the proxy passdb file, authentication is completely up to the destination host. Setting 'nopassword' in no way means the proxy becomes an open relay. Is this correct?
1.2 Are there any security implications when using 'nopassword' on the proxy?
2.
2.1 I would

Dynamic DNS for Samba domain joined hosts
Dear all
I have a Ubuntu 18.04 box with Samba 4.7.6+dfsg~ubuntu-0ubuntu2.16 on it. Until recently I only used winbind on it to
enable GSSAPI for ssh and Apache. The machine is domain joined to a 2016 based set of AD DCs.
I have added a IPv6 static address to the box and want to update DNS dynamically.
I installed all of Samba to get "samba_dnsupdate". Prior to this I only needed

Samba AD with internal DNS on IPv4/IPv6 but only announcing IPv4 address
Hello,
I use Samba AD in Version 4.8.3 and would like to run it on IPv4 und
IPv6 in order to be able to have Samba acting as IPv6 DNS Server.
However since I have problem with sysprep domain join as soon as Samba
advertises its own Domain Controller Hostname as IPv4 and IPv6 address,
I would like to tell Samba to run on both protocols but only resolve to
an IPv4 address. So in short:
When I
