General :: Send Mail From Domain As A User That Does Not Exist As Well As Email From Other Non-existent Domains
Jul 31, 2010I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.

View 12 Replies View RelatedUbuntu Servers :: Postfix Configuration - Send Mail To Other Domains
Nov 5, 2010Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:
telnet localhost 25
ehlo localhost
(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?

Jun 14, 2011I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.

Server :: Unsure Of Exim Configuration - Accepts Mail From Users On Multiple Domains To Pass On To The Outside World
Dec 29, 2010I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?

Ubuntu Servers :: Sendmail Can Only Send To External Domains
Jun 15, 2011When I use sendmail (or, most commonly, a PHP or Perl script uses it) to send to any other domain except my own, it works great. When I use it to send to my own domain, however, it's trying to deliver it to localhost. Problem is, all our mail is handled by an Exchange server on a different machine, so I really don't want If I run sendmail manually for a test message to myself, here's how it comes up after the message is closed out:
Code:
echo "Subject: test" | /usr/sbin/sendmail -v me@domain.com
354 Enter mail, end with "." on a line by itself
>>> .
050 <me@domain.com>... Connecting to local...
[code]...
The message then gets dropped into my box at /var/mail/xxxx, but that's really not helpful to me -- I need to to connect to that other machine to deliver the mail there. This machine isn't used as a mail server at all. Also, if it's trying to send to a username that doesn't have an account on this server (we have many), it just fails entirely with "user unknown" (that makes sense, as there are only a couple of user accounts on the web server). how to get sendmail to connect to our mail server instead of "local"?
Networking :: Two Hosts On DDNS - Can Send Two Domains Through One Router
Feb 11, 2011I have two virtual hosts that I want to be able to send through one router. I have two seperate dynamic hostnames on dyndns.
Apparently my router allows me to enter two seperate hostnames locally as well: DynDNS Host and Domain Name
Code:
How do I tell the router which is which? Currently I see the same site with both URLs
Do I have to set one vhost to do some 'funky' stuff (black hole in my head when it comes to static routes or BIND? ). And then set the other vhost to host both sites?
I'm running CentOS and an apache webserver. I want to demo a web site 'externally' from two different sub-domains.
I've looked high and low but most examples don't seem to be simply trying to put two different web-sites up to two Dynamic DNS Hosts.
It must be possible, all the pieces are there. I'm just missing the link!

Server :: Send And Receive E-mails To And From An Array Of Virtual Domains?
Jan 4, 2010I've set up a fully functional e-mail server and can send and receive e-mails to and from an array of virtual domains without a problem. The only hiccup I have is that only root is able to send e-mails via mutt. I have not stipulated a sendmail line in the mutt configuration so it's sending e-mail with default configuration. How can I get it so that all users on the server can send outgoing e-mails via mutt?
