Ubuntu Servers :: Fail To Receive Emails From Other Domains?
Oct 7, 2010
My email server (Postfix + Courier + virtual dropboxes) can receive internal emails, but if the email is sent from the exterior (like Gmail or Hotmail) this email is returned to the 3?rovider (like Gmail):Delivery to the following recipient failed permanently:xxxx@xxxxxxx.xxxTechnical details of permanent failure:Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, no mailbox here by that name (#5.1.1) (state 14).
----- Original message -----MIME-Version: 1.0I've tried a lot of things, I've used this guide:http://flurdy.com/docs/postfix/My Ubuntu Server is 10.4 (Lucid), I had the same configuration with a previous Ubuntu version and everything was right.
I've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL] 2) All other users can receive and send mail from/to any domain.
Our main DNS resolves to a windows 2008 server box. What I want to do is have a secondary box with Ubuntu to receive sent emails (our@our.com). The problem my brain cannot get around is the DNS resolves to the windows server 2008 box(which host the website as well), how can we allow the email (ours@ours.com) to go to the Ubuntu email server even though the DNS name resolves to the windows server? We need the Windows Server but just Don't want it hosting our mail.
I 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.
It is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.
PS. I was thrown into the position and have limited knowledge. I am used to a GUI.
I want to setup an email client in order to send/receive emails, but since i am experiencing some issues with my ISP, i decided to setup an SMTP server with Postfix on my machine.The problem is that i can receive emails but i can not send.I read almost every thread in here refering to Postfix, but i could not find the problem on my configuration.So here it is..
Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first
I have s smtp configured server , the problem i am facing is that i am not able to sent emails to some domains for instance yahoo.com or ymail.com rest all domains the email goes through
I'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?
Update: Solved this by following this http://inmyplace.info/2008/05/07/pos...ission-denied/
I have configured Postfix on a Ubuntu 8.04 box using this tutorial:I can send emails but I cannot receive any email because of a "bad recipient address syntax:"The log from /var/log/mail.info says this:
I'm wondering why we can't received email when our primary DNS went down. We have slave DNS but don't know why we can't receive emails. Internet is working properly. The mail file in /etc/configuration on slave dns are there & the zone file is added. I edited the mail zone file to see if it works & restarted the named service. But still we can't received emails using the slave DNS. Do I need to reboot the server?
i'm using fedora 12 and i wanna send mail using command $mail actually i tried to send mail to my gmail , yahoo ,and hotmail emails but i didn't receive the mail so i expect that i should have some configuration on my host before sending mai
Could it be the IMAP file is corrupt?I have set up mail server on Centos to receive via dovecot.One of my user accounts (A single account out of a hundred)cannot receive their mails.
To start off, I realize this type of question is very hard to answer and there is no general rule. My intention is to merely get an understanding of what others are doing. Models: 1) small piece of a big pie, but many small pieces 2) big piece of the pie, but few pieces. Which model do you guys do? If one can make $100 from a site which little or know effert, why not create 100 sites like it? Benits: diversified with multiple revenue streams, hard to manage so many etc etc. OR Work hard on 1 site, focus, narrow the niche and make loads of profits. drawbacks: all eggs in 1 basket Which model do you guys employ?
I've built a web hosting server with ubuntu 9.10 desktop edition at home and it's up and running.how to get and set subdomains. What I mean is that I have a purchased domain [URL] and I want to add as many sub domains as I want such as [URL] so on. And more importantly every single subdomain must belong to each account.
sub domain account name ------------------------------------------- sub1.example.com john sub2.example.com steave sub3.example.com myname
In this case, there are three accounts for ubuntu and each account has a permission to the corresponding sub domain only. p.s My DNS is managed by my domain company and it provides a web page where I can forward(not sure, but there are fields that I can type my sub domains) subdomains and my external IP addresss up to 20(just in case this info matters).
I've tried to set up an old laptop with Ubuntu server - need to use it as a web server for a group of students on a local network only. I managed to get it working fine for just one user publishing webpages etc to a folder called VAR/WWW I could FTP files into the folder and access them again via FTP or a browser. I then decided to create some subaccounts (one for each student) I did this by typnig the following commands:
(In this example student1 is intended to be a subfolder of www and act like a sub-domain with write authority- at least that was my intention) Problem I then get is that if I use Filezilla to access each account I cannot see where to publish the files - wherevever I place them they are not accessible from the browser. Do any of you experts out there know the answer to my problems please.
I would like to set up an ubuntu server to forward outside requests directed to different domains to different computers on my local network. The bind is I only have ONE public IP.
Here's an example of what I want to do.
- if a request is sent to www.first-domain.com, I want to forward it to a local server (say 192.168.0.10)
- if a request is sent to www.second-domain.com, I want to forward it to a local server (say 192.168.0.20) and so on...
I will need to forward these requests not only for web sites but for other services such as SSH, mail, RDP, VNC, etc etc PS Once it hits those local servers, I know how to use iptables to forward them as desired.
I followed this tutorial: [URL] But the links i created are not accessible. Is it to do with [URL] not working? I was doing [URL] and [URL], but didnt work
I have just installed iRedMail-0.6.1 to my Ubuntu 10.04 powered server. I can receive emails from mail accounts on my server and I cal also send emails from those accounts to other servers like gmail.The problem is I cannot receive emails from gmail, hotmail or any other server.
I'm going to be setting up a couple of servers for some friends. I'd like them to be able to email me some information after they do some maintenance scripts via cron. I got my own server to send email using a tutorial I found but that involved using my personal gmail account. getting email sending working on ubuntu server with minimal fuss and account credential exposure?
I've set up a mail server using Postfix + dovecot. It works just fine sending email to users in my domain. However, I can't send email to external domains (like gmail, yahoo, etc) different than mine. I've tried sending from a remote connection using Evolution and I get the following message on mail.log
Jan 8 10:45:20 mail postfix/smtpd[14911]: connect from unknown[] Jan 8 10:45:21 mail postfix/smtpd[14911]: NOQUEUE: reject: RCPT from unknown[]: 550 5.1.1 <lobomacz@gmail.com>: Recipient address rejected: User unknown in local recipient table; from=<user@mydomain.com> to=<lobomacz@gmail.com> proto=ESMTP helo=<[10.24.4.230]>
I'm having a problem with a new install of postfix... it won't relay mail to external domains. Internal mail is fine.I'm using virtual_mailbox_domains so that I can have multiple domains, and I've set dovecot to use local files with encrypted passwords.Here's my main.cf
how can i configure my server to send mails from about ten different domains i use google apps and want to know if its possible. Because it sends mail but all goes to spam and i have a static ip
I have a domain.com site up and running on my server. I just bought domain.net, domain.org and I would like it to point to the same site on domain.com. I am not sure how to go about doing this.I used zoneedit for my dns. So far I have pointed my 2 new domains to the same dns as my .com on zoneedit and I have created (A) ip address for them. If I did this correctly, the new domains are pointing to my server and all is left is to edit the virtualhost?
I work for a college with many departments. I'd like to just deploy one LDAP/krb5 server (plus slave replicas) to authenticate all users in all departmentsIs it possible to do this?The proposed DNs for the departments matches what is done for NIS now.If anyone has any pointers or URLs that describe how to properly do this.
When 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"?
I am going to try and replace our crappy Windows/imail server with a new ubuntu 10.04 LTS based machine. It will end up with about 400 domains on it with around 3000 users total. 96% of the domains have very light use. 4% of the domains have heavy use but do not send any bulk mail.
Can someone here recommend a mail server software package that would be easy to administrate and easy to backup/replicate? All we need is POP with webmail. We do not need IMAP or want any group/collaborative functions.
What do you usually use for anti-spam on a linux mail server? We want to keep it all open source if possible.
For hardware we are looking at an HP DL360 G5 with dual Xeons, 4G of ram, and the P400 controller with 6 SAS 15k drives. Do you think a server like this will be able to handle the mail on linux? Volume is around 400k messages a day inbound with about 10% being legit/90% being spam. The server will be dedicated to mail hosting and will not host websites.
