a user reported mail client message:
"It hard to sent mail we try 2-3 times then sent."
screengrab from mail client had: sending failed, couldn't send, connection
to outgoing server timed out
I couldn't noticed anything, tail maillog, saw emails going, probably
looking at wrong things ?

Viktor, I think and I'm afraid you've hit the nail on the head... that's

see how much spam spamcop stops that isn't
coming from Microsoft. Maybe I could whitelist the Microsoft IP space in
rbl_override.

I still have that problem with the sender that used a spammy microsoft
server that gets rejected by IP for using spamcop. I put the domain in
the client_checks file but the sender gets bounced.
postconf mail_version
mail_version = 3.8.1
compatibility_level = 2
The client_checks line was added
Well do I put the domain in sender_access or sender_checks?
It looks like sender_access with an OK since it acts on the FROK field.

I have a sender_checks file but I don't see that on the postfix.org website. Is
that a deprecated parameter?

My sender_access file contains
charity.donation.jp REJECT
postmap -q charity.donation.jp hash:sender_access
REJECT
So it returns REJECT as expected. However testing some random users at
the domain:
postmap -q m...@charity.donation.jp hash:sender_access
returns nothing. Is the domain being re
I can tell you there is significant spam from that Microsoft IP space. That
spamcop doesn't have false positives, but rather due to the sharing of IP
space, senders that aren't spammers get tarred with the same brush as the
spammers. I did a grep on the maillog files and that is a firehose of s
I have a small email relay server that is used to allow IOT devices to send
email. Some of those devices do not do authentication. I'd like to
restrict the sender domain based on the IP.
I'm looking for something like smtpd_sender_login_maps, but for client IPs.
Example of a smtpd_sender_login

Hi,
I was reading the SASL_README, "The ldapdb plugin" at:

Tip: [...snip...] Instead, you can use "saslauthd -a ldap" to query the
LDAP database directly, with appropriate configuration in
saslauthd.conf, as described here. [
