Ubuntu Servers :: Incoming Email Not Going Through (connection Timed Out On Mail Server)?
Sep 1, 2011
I have been trying to solve this problem for two days now looking at various forums and websites but can't really figure out what's going on here.I have setup postfix on my ubuntu and I can send emails using "telnet localhost 25" and the ehlo thingy. Apache can also send emails. My problem is with incoming emails. When I try to send an email (through Gmail) I get the following error message:
Code:
Delivery to the following recipient has been delayed:
root@example.com
[code]...

I have 2 different networks :the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [url]..... on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7, CentOS 5.
I could say that the problem in DNS:because when I use this command in the private network machine: [url]...., it says connection timed out; no servers could be reached ,while in the public one, it works properly.....

I have a problem sending emails in the command line. I have introduced this command:
sendEmail -f my.account@gmail.com -t myself@domain.tld
-u this is the test tile -m "this is a test message"
-s smtp.gmail.com
-o tls=yes
-xu usernameonly -xp mypasswd
But then I received this message:
sendEmail[13230]: ERROR => Connection attempt to smtp.gmail.com:25 failed: IO::Socket::INET: connect: Connection timed out

In a little over my head here but eager to learn. Running Fedora 10 on an IBM T41. Trying to set up a local server so that I can run PHP and test webpages locally (I'm a client-side web designer). Went through the SendDerek tutorial and everything went great until I tried to check the port with canyouseeme.org. I get "Connection timed out" every time.
- The httpd service is started via the terminal.
- Port 80 is unblocked via "Firewall Configuration."
- I set up port forwarding on my router.
What am I missing? I just want to be able to have the local computer run my PHP scripts instead of having to upload them to a remote server every time I make a change.

Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf

I installed a new server running CentOS 5.2. I have iptables and SELinux off. The new server will not accept incoming mail. It will send out fine.Our mail server redirects mail for it.help to it.[url]...- [url]....is this server. Any messages sent to this address get stuck in a deferred queue. The error message on each one (from the mail server admin console) is "connection to[url]... [10.9.10.202] - connection refused". I can ping [url].... from the mail server.
This seems like a firewall issue, but it is off. Is there some configuration file I need to change to allow incoming mail? Or is there some test I can run on the new server to further troubleshoot what is going on

What is the absolute quickest or easiest way to block an incoming connection by their IP address? I'm running an apache2 LAMP server on Ubuntu 8.10. For example, let's say I'm watching my server error logs and I see someone using a script to check for phpmyadmin and other such folders. Right away I know this is a hack attempt. Firestarter does not allow ANY way to block an incoming connection by IP (to my disappointment) and adding the IP to an apache configuration file requires an apache restart (way too much trouble and time).

As a part of migration I am proposing different scenarios to my organization. One which is asked to prepare is to configure multiple mail servers to handle incoming and outgoing mails. Say I have -[URL], I need to have accept mails from [URL] and send mail from [URL].

I have a server with a domain running and im trying to resolve the mail server but i can't see where to start. I use OpenSuse 11.2. Basically, for starting, i want postfix to send incoming emails to a php script or perl. for outgoing emails i guess that i could use php mail function and i will see what else to have. I configured the dns. I do a dig.mydomain.tld MX and i get the following:
mydomain.tld3600INMX0 mail.mydomain.tld
mail.mydomain.tld 3600INAmyNumericalIp
So now my system is receiving MX content but i dont know what to do.

I just setup a mail server on my web server and I cannot for the life of me figure out how to send emails to external (as in outside my LAN) emails or receive from external emails. I'm using Postfix with Dovecot and Squirrelmail. I get this delivery report in Squirrelmail when trying to send an email to my hotmail address.
Final-Recipient: rfc822; example@hotmail.com
Action: failed
Status: 5.0.0
Remote-MTA: dns; mx3.hotmail.com
Diagnostic-Code: smtp; 550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. [URL] maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit [URL] for email delivery information and support.

I've been trying to ssh out of my home network to school computers and I keep getting:
ssh: connect to host sage.math.washington.edu port 22: Connection timed out
I've tried this on my machine (running Ubuntu 10.04) and on a windows 7 machine (using putty). I have been successful ssh'ing to this machine using either of the laptops from every other network I've tried, so I'm pretty sure it's something about my home network.

I have recently setup a new mail server and have simulated sending and receiving on the new email server. The new email server will replace the primary one.I would like to setup the new email server in parallel with the existing one.This way i can observe issues that might occur and be aware of what could go wrong. I want to received mail to be delivered to both mail servers at the same time.I would like to use postfix, exim i find a bit to difficult to understand.I have thought of using transport maps, the only problem is that you can only forward mail to one server at a time using transport maps.I think recipient_bcc_maps and sender_bcc_maps could work, i would just like ideas of how i can do this.

I have recently set up an ubuntu 10:04 based email server using postfix, clamav and squirrelmail. The setup works like a beast, much better than the old sco based system we were using. Anyway I work for a law firm, and we have use a bespoke case management system to complete work on cases. We have started a paperless office initiative. This means we are asking more and more clients and firms to correspond via email. This is where my troubles are kicking in. The governing body of solicitors in the UK is very picky, and we have to have certain formats and information in documents when sent out to clients, this is the same for emails.
I have a script that will cat the html header information, then cat the body of the email and finally cat the footer html information. The output of which is perfect and usable to the firm. My problem comes sending this file. The end of the script I have the following:
Code: mail -s $SUBJECT $CLIENTS_EMAIL < email.$$$ Pretty self explanatory. But when the email is sent from the mail queue its not delivered in html format but in plain text. Any email sent using outlook from any machine on the network can send and receive html email. How can I make this happen from the command line?

I am trying to confiugre sendmail client and server environment. A very simple environment. On server side I configured sendmail and relaying the requests from other linux machines. On a server end emails are going out fine but on client side its not working with Deffered message in log. I tried to find any solution online but couldnt get any exact info to sort out this issue.On server side there is a entry of client machine in /etc/mail/access and I created access.db as well with make hash command.Is there something on server end that is not responding? or if I am doing something wrong please point out.

Sometime, I got the error messages as I mentioned in the subject:
Quote:
Feb 14 07:46:48 x proftpd[27487]: x - Fatal: unable to open incoming connection: Transport endpoint is not connected
I'm sure there are some clients connect to server at that time. What does this mean exactly? Why did it happen? Below is my configuration file:
Code:
ServerName"ProFTPD server"
ServerIdenton "FTP Server ready."
ServerAdminroot@localhost
