We have a sever on which we made an upgrade from Ubuntu 8.04 to Ubuntu 10.04
We use telnet to access from one local machine to another in our local LAN, but after the upgrade, when we try to connect to our server from a client on LAN we receive the following error:
Is there any known issue about problems in telnetd and Ubuntu 10.04?
I am trying to set up postfix on my ubuntu server.When I try to login to the pop accounts through telnet
Code:

I'm not sure what when wrong since I have a few DVDs and they all play well in my normal DVD player, I later attempt to mount it in my Ubuntu 8.10 I'm presented with the following message:
DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
May I know what does this really mean?Is there something in my computer that require a fix?
I just completed migrating a Redhat 9 server to new hardware and a virtual machine. If I attempt to alter the time or date with the date command I receive the following message. "date: relocation error:/lib/tls/lib pthread.so.0: symbol __resp, version GLIBC_PRIVATE not defined in the file libc.so.6 with link time reference"
This also comes up during the bootup process along with "sleep: relocation error". I have never done I migration like this before and would consider myself a novice to linux. This server runs an old software package and I would prefer not having to totally reload it. The software we run appears to be run fine at first glance but I don't want to roll this out until all errors are resolved..
I have telnet service intalled(apt-get install telnetd), but when I type telnet, I'm getting the following error:
bash: /usr/bin/telnet: No such file or directory

View 2 Replies View RelatedOur 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.
View 1 Replies View RelatedSo I have a script that is supposed to check to see if a mail server is up and responsive. What I want to know is how I can send it the telnet escape character. I've tried:VAR=`(sleep 5;echo quit) | (telnet mailserver.timbuktu.net 25 2>&- )`
This works BUT there is a problem as the mail server may have been accidentally firewalled off. If this happens, my automated checking script will hang. What I want to do is send the escape character so that the '>' prompt comes up. They I should be able to send it "quit" even if it is hung on not getting a response from the server. VAR=`(sleep 5;echo -e '^]';sleep 1;echo quit) | (telnet arhqmg01.usarec.army.mil 25 2>&- )`
The above doesn't work. telnet interprets CTRL+] as '^]' but you can't type '^]' and get the same effect. So I guess what I need is to send the actual keystrokes. Like echo "somenumber" ; echo quit
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.
Every time I try to send a message with SquirrelMail, I get:
Code:

I do not know why I could send email outside but not receive. I use relay to my ISP that port 25 is blocked by my ISP. What can I doing with configuration when it should be works to receive mail? Okay, I have sent a test e-mail between localhost and it works. I can send from mailserver to my gmail without problem. So why I cannot receive email from gmail?

View 1 Replies View RelatedMy ISP recently decided to kill outbound traffic on port 25 for some reason. Therefore, I change the SMTP port to 24, everything work fine so far i can send email to local domain and remote.

View 3 Replies View RelatedI have a very basic install of dovecot and postfix on the latest version of Ubuntu server. This is an internal only email server with internal only DNS. I can send email via clients and check said emails via the command line when logged in as the appropriate user. I cannot for the life of me check said emails via SquirrelMail on the server nor using IMAP clients. I have no idea where to look and I can't find a basic tutorial for the life of me. Where should I start?

I hope someone can help me setting up receiving e-mail on my home server. Ubuntu Lucid and Zarafa from repository. Zarafa is running well. I can send e-mail via the relay smtp host from my ISP. But though the e-mail address should be correct I never see this e-mail appear in zarafa inbox.The e-mail reaches the server via an open 25 port forwarded to my server, but it seems postfix does not know how to handle it. Or is there something else going wrong here? Below are my settings. These are the settings I added or edited. the rest is Ubuntu Lucid (10.04) standard.
/etc/postfix/main.cf
Code:
myhostname = xxxx.dyndns.org
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

Alright guys, I've looked over every thread regarding this issue on this forum, and many others; yet I cannot find out why my mail is being bounced without error from my external gmail account.From what I've seen, you guys need to start off by seeing my postconf -n

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 used this tutorial to setup to setup iSpconfig postfix courier: [URL] but i cannot send or receive email:

Basically when i create users in ISPconfig, something goes wrong, mysql is running and i have postfix-mysql installed and running too.

I am able to telnet to the server via a remote connection, but for some reason, it will not accept mail. ere is the bounce back email I am getting.Quote:This is the mail system at host smtp.mydomain.net.I'm sorry to have to inform you that your message could notbe delivered to one or more recipients.

So we have DNS round robin set up for 4 servers. If we ping dns name (basically an alias) server_connect it resolves with different IP address in round robin format. I.E. x.x.x.1 x.x.x.2 for the 4 different server IP addresses. When we do nslookup server_connect it will come back first time as server1_connect server2_connect through server4_connect so the server is able to resolve through ping and nslookup resolving the initial dns name (alias) to the dns name associated in the round robin. Problem is when we try to connect with http or telnet it comes back host unrecognized. I can put one of the 4 round robin servers in /etc/hosts and it connects fine so I'm thinking that either one of three things.
1) ttl
2) It does double connection first to identify itself to the round robin server and then handshake but second time it hits for the handshake the IP and dns name is different than what it expected so it fails.
3) Since we are trying to telnet to dns alias and it is returning different dns name it fails.
2 and 3 seem most promising but now I'm at a stand still.Anyone else come across this issue and if so how did you resolve.
Regarding few things I am facing problem :
1. How to send one copy of that outgoing mail generated from the source. It should cc to another mail id in server's backend while mail sending.
2. I don't have any domain - internally or externally. Only have static ip, accessible from outside. Can I configure sendmail to send-receive through that ip.
3. How to transfer all mails and addressbook from exchange server to linux sendmail server.
I have been running an email server on a Red Hat 9 system for 5 years, and wanting to upgrade it to the latest Fedora OS. A few days ago it crashed. The server is running Fedora 11 (up-to-date). Clients are Fedora 11 and Windows XP machines using Thunderbird for accessing email. The server is running Postfix and Dovecot. Within my local network I can send and receive emails. I can also send email to addresses outside of my local network. The only problem is that I cannot receive any email from outside the local network. I cannot think of anything aside from my firewall (iptables) or postfix config that could be causing the problem.
Below are my iptables file, and the postfix main.cf changes that I have made.
Iptables (the same file I was using on Red Hat version 9 with one minor deprecated syntax changed):
*nat
:PREROUTING ACCEPT [22:1894]
:POSTROUTING ACCEPT [14:840]
:OUTPUT ACCEPT [17:1356]
-A POSTROUTING -o eth0 -j MASQUERADE

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..

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.
Received this random error from the update manager today.
Code:
Since upgrading to 11.04 yesterday, nauilus has been acting strangely. It takes about 30 seconds for a right click on the desktop to respond, whereas before it would've taken 1 or 2. Also, when trying to open a directory, say, the Home direcotry accessible from the launcher,it takes about a minute to open, which is odd,because all of my other applications (Chrome, Banshee etc) ares all running smoothly. And when the direcotry windowe does open, within 10 sconds it will turn grey and prompt me to force quit. When i try to open nautilus from a terminal, it comes back with the message
Code:
