Sendmail, I think this is easy, but can someone help?
 

Hi all,

I was hacked a few weeks ago and my sendmail server was switched to open relay. I fixed it, but in that time, I got "blacklisted"! ARGH!! The final list I need to get off of is trying to send me a removal confirmation e-mail to my "postmaster" address. My domain is "bubba.net". The problem is that they CANNOT send this e-mail to postmaster@bubba.net. They can only send it to postmaster@[1.1.1.1] (where 1.1.1.1 is my IP address). How can I setup sendmail to accept mail bound for "whatever"@1.1.1.1? Does anyonw know how to do this? Please help!! Thanks!!

Chris

It could be that bubba.net does not resolve to your ip address, this would be a DNS problem, maybe you need to update the domain name if your ip address changed.

I am able to connect to bubba.net and send mail to postmaster, it says message queued

check /etc/mail/aliases for an entry like this ...

postmaster: root

that's the default entry

you may want to add an entry like this to get root's mail,
user being your user name

root: user

run this to update the aliases

sendmail -bi

I was also able to send to postmaster@mail.bubba.net

which is your MX record for bubba.net

I also sent one to your ip address

Did you get the messages I sent

check the contents of /var/log/maillog

Oh jeez,

I'm very sorry David! bubba.net is not ACTUALLY my domain. I was using that as an example and forgot to mention it! Oooops... My REAL domain is bartlett-family.net!!! Sorry!!! Please try again and let me know what you get, because when I try to e-mail postmaster@[my_ip_address], I get an error message saying relaying denied.

Chris

PS. I know you can just do a "whois" to get my IP address, but I didn't want to type it. It's 24.61.77.188. All I need is for an e-mail to:
postmaster@[24.61.77.188] to go through ok, and to be redirected automatically to the user "chris".

this is what I get

telnet mail.bartlett-family.net 25

I will try an email client

here is what I get in my log file when I send through my mail server

May 28 22:59:01 www postfix/smtp[29748]: EE82B13C8D: to=<postmaster@bartlett-family.net>, relay=smtp.comcast.net[24.153.64.2], delay=1, status=sent (250 2.5.0 O
k.)


which is relaying through my isp just to please AOL's stupid non-complient mail servers

looks ok

The only problem I can see is the servers name is not valid in terms of DNS

you should change it to mail.bartlett-family.net or some other valid address just to satisfy the picky if for no other reason

David,

I got the e-mails you sent to postmaster@bartlett-family.net, but that's not the problem. I need to be able to get e-mail at this address:

postmaster@[24.61.77.188]

my db file in /var/named says:

MX 50 mail.bartlett-family.net.

Does that help? Lemme know what you think!

Chris

Open /etc/mail/sendmail.cf for edit
Search "Dj" u will see your domain , change it and save

Nah, that wasn't the problem. I wasn't using cw_file. I added that in sendmail.mc, remade the configuration file, restarted sendmail, and hoowaa! All set. Thanks for all your help, guys!

Chris
