Hello, all.
Since yesterday, I've started seeing email from my servers getting
rejected due to SPF problems.

Hello, all.
I handle two SMTP gateways at $WORK which relay mail from the internet
to an internel server and vice-versa. Accordingly, I have

We recently had a network issue between the gateways and the internal
host, after whi

Hello, folks.
I use postfix on two mail gateways and I'm seeing inbound mail
using one of my domains. I thought I could block this using
smtpd_sender_restrictions but, even after adding the following
line to /etc/postfix/main.cf:
smtpd_sender_restrictions = permit_mynetworks, \

Once I added this to my main.cf and reloaded postfix, I saw that emails
were getting correctly delivered. Thank you, Ralf!

Hello, all.
Last weekend, $WORK moved over to 2 smtp gateways running
postfix/clamav/spamassissin. This setup has been running with only one
issue: two domains refuse to accept mail from us.
Investigating this, we realized that both domains use the same mail
servers and that they both require TL

Note that you can use transport maps to use a relay only

If you can't use POP or IMAP, I'm pretty sure that you're stuck using
MAPI, Exchange's native (and non-standard) protocol.

Hello, all.
I'm using a mailrelay and an internal server setup.
The mailrelay receives mail from the internet, runs a number of checks +
spamassassin + clamav then passes mail to the internal mail server.
One of the checks enforced on the mailrelay is

What is the DNS server? On what OS is it running?

tance of SA instead of two.
What's the best way to do this? If I install SA on the first domain
and remove the lists.example.org MX, spammers will still be able to
send spam to it directly. Is setting up SA on both machines the simplest
way to go?
