Subject: Re: [Off topic] sending mail from Comcast was: Sendmail not working
OK, I've fired up a new VM, new CentOS 7 install, now I get this:
# rpm -qf `which sendmail`
postfix-2.10.1-7.el7.x86_64
I meant to say i OWN the domain
Can you point me to how to set this up properly? Note that I won the
psalm19pix.com domain, it's hosted at fastmail.com, and as far as I know
requires SSL. Can I setup sendmail to use this as it's SMPT connection?
No idea what all of that means. Contact support at fastmail.com? I am only helping with you sending mail from Comcast ISP.
Thanks again...

I followed this guide:
https://pepipost.com/tutorials/install-sendmail-server-centos-7/
Sigh - bad examples for you.... undo if you can.
Postfix provides the "sendmail" utility.
# rpm -qf `which sendmail`
postfix-2.10.1-7.el7.x86_64
now I get this:
# echo "Subject: sendmail test4" | sendmail kevink@xxxxxxxxxxxxxx
[root@kdb-bugs auth]# echo "Subject: sendmail test4" | sendmail -v
kevink@xxxxxxxxxxxxxx
kevink@xxxxxxxxxxxxxx... Connecting to [127.0.0.1] via relay...
kevink@xxxxxxxxxxxxxx... Deferred: Connection reset by [127.0.0.1]
Closing connection to [127.0.0.1]
What does /var/log/maillog say ?
Thoughts?

All;
I installed sendmail via yum, but if I test it like this:
The original message was received at Sun, 19 Apr 2020 10:02:56 -0600
from localhost [127.0.0.1]
----- The following addresses had permanent fatal errors -----

.org/query/ip/50.243.150.81)
Is 50.243.150.81 your system's IP address? If so, as this shows, that
IP is on spamhaus' blacklist of addresses. Thus, your sendmail is
working fine. Problem is elsewhere.
anything I can do to fix it?
Assuming this is your IP address, visit https://www.spamhaus.org/lookup/
and request that it be removed from the blacklisted IP's.
However, looking at the headers from your message, it appears Comcast
may be your ISP, and this 50.243.150.81 IP address appears to be a
Comcast address, so you may need to contact Comcast tech support for
help in getting the blacklist designation removed.
There are a few situations here.
1. You are a business customer with a static IP, and are entitled to send/receive SMTP by your ISP
(Comcast)
2. You are a business/residential customer who is allowed to send (not likely allowed to receive)
SMTP and you have a domain elsewhere to receive replies to your email
3. You are a business/residential customer who is NOT allowed to send SMTP except for your ISP
(Comcast) provided email.
Only you would know which on for sure is you, but it is very likely #3.
The advice provided previously is for case #1 - contact Comcast and inform them that your
contracted
services are not working because of .... and you will need to beable to work with them on testing
and
suggesting fixes. They have a dedicated support phone number (which they provided you if you are
actually a #1 type customer - e.g. gigabit pro, metro Ethernet, etc.)
In case you are a #2 or #3 type customer, you may want to use a smart host configuration - e.g.
define('SMART_HOST','[smtp.comcast.net]') . For postfix, use relayhost = [smtp.comcast.net] .
Now when you send mail to that relay it will relay it. This is provided you are entitled to have
your email relayed - contact Xfinity customer service for help there.
If using this relay does not work, please post the exchange starting with the HELO (check your
maillog or do it by hand with telnet).
