Hi,
I sent a traceroute output from my local machine just a few minutes ago,
and Jaroslaw Rafa used the website ping-admin.ru to trace from some of
their own monitoring nodes. I do not have IPv6, so unfortunately can't
do traceroute6 from here.
you can take also a look from https://mtr.sh/, th
Hi,
I think your system is using systemd-resolved for DNS lookups; this
hands off the real work of resolving to public resolvers, so RBLs will
block your lookups. This is a normal setup for a systemd-based distro
but is not appropriate for a mail server.
We don't know if systemd-resolved uses

Postfix is running here on Arch Linux, so usual glibc and no musl is used.

Hi,
according to [1] since 2.8 postfix uses ipv6 as default for
smtp_address_preference. But as stated in the doc, it is unsafe as only
IPv6 connectivity is broken, so the safe variant would be any.
Wouldn't it be an alternative that smtp_address_preference could be set
to "ipv6, ipv4" or "ipv4,

Hi,
That was a long time ago. Postfix has evolved as the Internet has
changed. I am continuing the overhaul of this software, motivated
by people like you on this mailing list.
I just wanted to say thanks - for postfix and your support on the
mailinglist!

Hi,
Personally, I find this type of one-way communication annoying and
impolite. The same goes for setting Reply-To to your personal email
address after asking for help on a public mailing list.
Like you did yourself?

Hi,
After I added my laptop's IP address to TrustedHosts file, the emails were sent
with DKIM signature.
Why don't you send mails authenticated? I would also assume a laptop
isn't always in the same net as the mailserver.

Hi,
How would you solve it?
Point relayhost.domain.tld to multiple IPs / servers? If one times out,
the other one will be tried.
