I have a issue with a message I'm trying to send to a hotmail user via sendmail.

Here's what I'm getting.

May 1 09:40:12 prodws01 sendmail[11240]: l41EeBMp011238: to=<xxxxxxxxxxx@hotmail.co.uk>, ctladdr=<xxxxxxxxxxxxxxxxxxxxxxxx> (0/0), delay=00:00:01, xdelay=00:00:00, mailer=esmtp, pri=120435, relay=mx1.hotmail.com. [65.54.244.136], dsn=2.0.0, stat=Sent ( <200705011440.l41EeB90011237@xxxxxxxxxxxxxxxxxxxxxxx> Queued mail for delivery)

The question I have is this part "Queued mail for delivery". Is that a message from us? Or is that from the recipeants mail relay? I noticed that it said sent. But as this being a customer, I'd really like to know if we are in the clear and if it's his email not letting him get it.

Thanks,

Charlie

The "Queued mail for delivery" message is from the mail server where you sent
your message. The mail server is sayng to you "I'll deliver your email when I
take care of other emails that came in ahead of you.

What version of Sendmail are you using ?

Thanks for the reply. I have found out more stuff which makes my situation more complicated. But first to answer your question.

sendmail version = 8.? (I can't find the version exactly)

It appears that this is strictly a hotmail issue I'm having. All mails go thru except for hotmail. When it queues the mail, it just doesn't go through. It doesn't go to junk. And it doesn't pass go and collect 200 bucks. They are just dropping my mails.

Is there any real sources of what is needed for hotmail to accept my email?

Here's what I have going:

I have reverse dns for the server.
With that I have the server in my dns A records as well.
I have created a spf record for this server.

Not sure what else I really need?

Thanks for the help.

"sendmail -d0.1" will tell you the version of sendmail you are running.

I had a similar issue with @mac.com addressees.

Does "dig" or "nslookup" resolve hotmail.com (or mx1.hotmail.com)?

I was using my router (192.168.0.1) to resolve domain names but some domains weren't being resolved.

When I explicitly added the name servers my ISP recomended to /etc/resolv.conf my problems disappeared.

// resolv.conf
nameserver 207.69.188.171 ;recommended from ISP
nameserver 207.69.188.172 ;
nameserver 192.168.0.1 ;my router

I think this may be of more service to the problem.

I ran an nmap from the outside to my server. Port 25 is not open. It should be, it's explicity alloweed in iptables.

So just to test, I turned off iptables and ran nmap again. A ton of ports showed up, but still not port 25, wtf.

Ran nmap on the server itself with nmap localhost. and port 25 shows up. SElinux is off. There is nothing in my hosts.allow/deny.

Perhaps there's a program / daemon not running that needs to be to have external smtp connetions?

sendmail version = 8.13.1

From your original post it sounded like you just couldn't send to hotmail.com; can you send to anyone?

Does your ISP allow users to send their own mail? Some, like Earthlink, require that all outgoing mail be routed through their authenticating server. If so, you need to configure sendmail's SMART_HOST.

Nope, can't relay to my ISP for email.

I can send to anyone though, just not hotmail.

I think I need to do something to be able to have server authenticate to our servers. And since I don't see port 25 from the outside, I htink I am missing something there.

So here's what I did, and I now can successfully send email to hotmail.

1.) modified firewall to allow port 25 connections thru
2.) restarted the sendmail program (service sendmail restart)
3.) Created a new spf file

Tried it all this morning, mail hits the inbox of my test hotmail account. Woo hoo!

Thanks guys for the help.
