Adding new user and getting sendmail to work

Ser Olmy · 05-11-2012, 01:46 PM

That message just says that your mail client is checking your mailbox using POP3.

Receiving a mail with an unknown recipient generates a log entry like this:

Code:

May 11 07:08:09 mail-gw sm-mta[18609]: q4BGPcqJ018609: <user123@domain.com>... User unknown

Again, are you sure this is the only server involved in receiving mails for this domain? Does host -t mx domain.com list the name of the Slackware server, and nothing else? And does this name resolve to the public IP address of that server?

Also, do you see the names of the other users in /etc/mail/aliases?

Sorry it has taken me so long to get back, I was called away.

When I type "jed aliases" it opens to an empty box and there is nothing in there except what I type.

I ran the host -t mx domain.com and got the following:

domain.com mail is handled by 200 domain.com.s5a2.psmtp.com
domain.com mail is handled by 300 domain.com.s5b1.psmtp.com
domain.com mail is handled by 400 domain.com.s5b2.psmtp.com
domain.com mail is handled by 100 domain.com.s5a1.psmtp.com

There is nothing about the calendar in the /etc/HOSTNAME file

Sorry again,

When I go into the aliases file, I can see a bunch of different aliases, to include the one I put in for me.

How about when you type jed /etc/mail/aliases?

When you ran host, I assume you replaced "domain.com" with your domain name. The results say that four different servers, all belonging to psmtp.com (Google Postini), accept mail for your domain.

I don't know how "Postini" works or which of their filtering services you're using, but it's possible (I'd say quite likely) that one of those servers are rejecting your mails. You should log in to your organization's Postini account and see if it does filtering by recipient address.

I did replace "domain" with my actual domain

I can't find another system with postini running on it.

"Postini" is not something you're running, it's a mail filtering service operated by Google.

Mail to your domain is not delivered directly to your server. Instead, it is sent to Postini, which does some kind of filtering and forwards the remaining mails to your local mail server.

You need to find your organization's login details for this service, and then log in to the Postini Message Center.

Ser Olmy,

You were correct. It was that the last guy in my position departed with the information on logging into and using Postini. Of course getting them to reply to my emails has been another pain in the rear.
Thank you for all of your assistance. I will continue to use some of the tips you have given me through this.

Mike
