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
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
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:
I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)
I have QPopper and Sendmail setup on a Red Hat server, they both seem to be running ok and listening on usual pop and smtp ports 25 and 110.
QPopper is running through xinetd and the config file is as follows
Code: service pop3 { disable = no flags = REUSE socket_type = stream wait = no
[Code].....
The problem is I get an error in the maillogs when trying to send mail from a PC on our local domain about the canonical client name which is to do with reverse dns. I understand this can be turned off at runtime of qpopper but nowhere seems to detail how to do this, apart from -R flag at runtime but as it is running through Xinetd I am not sure where to put it.
A few more details on the problem, if I VPN onto our network from my home desktop I can send mail fine. Receiving mail is also no problem, it is just sending. I have setup only our local domain in the access file for sendmail.
Have tried to setup email aliases in sendmail so I can have multiple address pointing to one linux login. However none of the aliases seem to be accepting mail.
I get the following error message when trying to send to them.
I have tried restarting sendmail, have mapped the /etc/mail/virtusertable across to virtusertable.db with the following command.
Code:
Output of sendmail -bv is as follows and looks correct.
Code:
Have also added new domain into local-host-names file. I am stuck on what is left to check and why the messages are getting bounced back.
I want to use my CentOS-Server for logging incoming phone calls using an AVM Fritz-Card.It should also be possible to notify clients (Linux and Windows) on incoming calls, or there should at least be a web-frontend.Is there any software like that in the CentOS-Repository available?Or is there another software like that, that is easy to install? I already asked google (an i will go on), but I couldn't exactly find what I want.
I have to administer a few mail servers, a mail log server, 4 nameservers and a web server -all running on Centos 5 server distributions. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and mail log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves. I have already installed VMWare Server 2.0 I have a few questions:
- How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? - How do I actually do this cloning? Is there a tutorial on how to do this?
i'm trying to send a mail with "mail" on my cent os console , but without success. In Suse it's quite simple with "mail": mail -r sendersaddress@domain -s "subject" targetaddress@domain </tmp/filewithcontent
I am setting up a server that is to serve websites and host mail.I have run into a problem regarding the mail server. The server is completely set up but for some reason it is not receiving the e-mails I am trying to send to it. When i mail to the associated mail address from internal by the "mail" command it works fine. But when I try from an external mail server, the mail never gets through. And I do not receive a bounce e-mail.
It says that the port 25 IS open for TCP connections (in iptables - I opened it myself). And surely when I telnet to it on that port from inside the server, I get an connection. But when I telnet from an external network I get a refused connection. It would sound that the port is in fact not really open for external use, in my mind, but it is. Is there possibly anything else I might have neglected to check in this mystery
i'm using Thunderbird as mailclient.n i receive a new mail, i want TB to run an application (which blinks my notebook-keyboardlight ).Is there a way to do that?And btw. does someone know, how to minimize TB 3 in the systray of gnome (Fedora 12)?to get the mailnotification icon in the systray?
I'm using postfix on Ubuntu 9.10 and all I need is to occasionally send automated emails from perl or php scripts when data processing errors occur. In other words, I want to reject any connection attempts from remote clients and otherwise allow nothing except outgoing emails from one particular account.f I add this line to the default main.cf, will it do the trick or is it more complicated?
I'm running SuSE 11 with sendmail and dovecot.I'm sending and receiving mail. But as soon as someone sends me a mail with an attachment over 1mg it seems to fail. I have no problem sending big attachments.
I plan to make a script for the console server via mail, but I find difficulties in the reading of email applications, to email me using the mail command, but how to read the incoming mail
assist me in using the iptables firewall to block all incoming mail traffic (SMTP port 25) except that of a certain IP(s)? the situation is that we have a server that we only want to receive mail from a particular sender.
I'm trying to set up my Thunderbird 3.1.8 (running on Ubuntu 10.04 LTS) to play a .wav file of my choice when new mail arrives. The file I've chosen is 8,8 KB in size and lasts 3 seconds. I've selected the "Play a sound" + "Use the following sound file" options in my Preferences, but only the first second (if that) of the sound gets played - both when I click the "Play" button in the Preferences menu to test it, as well as when receiving mail. Restarting the program with my new settings doesn't help.
Actual question(s): - Is there a limit on the size/duration of the sound one can use for such a signal in this program? - Is there any way to modify this limit?
Request your help in writing a shell script for the following requirement:
1) scan each incoming mail with conditions on sender name and subject 2) scan the mail body for set of characters and email them.
general usage is as follows: I get a mail as follows from: [URL]... subject : Urgent, reply body : name : xyz contact : 12345 the script should mail the following as subject line: n:xyz c:12345 I know procmail is a good option for this, but I'm compelled to use shell script
I've read many post close to my subject regarding blacklisting incoming emails, but non of them described what I really want:How can I reject a continuously changing email from my postfix, here is what I mean:
I think you got what I mean, the thing I've taken from the posts I've read is that I created a sender_access file hashed it and added the:smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/sender_accessto postfix main.cf configurationThe sender access file reads:abduooo*@googlegroups.com REJECTBut that didn't work, I know that there is some magical slashes and dots to be added to the sender_access, but I don't know which.

Recently did a fresh install of F12, previously used F11 without any problems. Now Evolution move ALL received messages to trash automatically. I have had to make rules to move each e-mail to the inbox but still all incoming messages go straight to Trash.
Having a problem with tftpd on CentOS 5.5. I am only able to download files from the localhost address.
I have checked iptables (by adding rules and by turning the firewall completely off -- nothing changes) and enabled tftpd logging (by adding -v to the server_args section in xinetd.d/tftp) and I DO see the request coming in, but no response from the daemon. I've also tried upping the verbosity by adding multiple -vs and/or --verbosity 10 to the mix, but all I ever see is the initial request come in, nothing more. I've even tried running the daemon in foreground mode with -L but I get no verbosity then.
I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
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.
I am running a CentOS 5.6 Server with a website and Forum. The website has a contact form and users can email various people in the organization. I have setup sendmail to send any mails like this to my email address on a Windows machine.The problem is that there emails don't have a header which has the senders original email header. It comes from localhost on my sendmail. How can I get any mail generated from the apache site to ALSO send mail to root on the Centos Server? That way I should be able to see the header and report the spammer or block them.
I followed the Wiki guide for configuring my Postfix server for SASL / TLS. I don't get any errors and I assume it's working but when I try and test SASL (saslauthd), I don't get the response noted according to the Wiki and I don't understand why.
