I just recently purchased a vs from a company and i am trying to set up a web site on it with kloxo and set up the mail for it upon setting up the mail settings it says:
"It is very essential that you set the my name to a properly resolvable hostname, since otherwise, many public mailservers like hotmail will reject mails from your server"
Now this is my first time setting up a vs before i have set up linux vm's to get email access but that was about a year ago.
I am trying to set up a Mail Server -- Virtual Users with Postfix, PostfixAdmin, Courier, Mailscanner, ClamAV On CentOS 5.5 using this guide. These are the version and softwares I have used till now:-
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 am setting up a virtual server on CentOS that I want to use as a VPN endpoint. How much resorce should I allocate to the virtual server ? I'm not expecting it to do anything else other than host a small VPN, traffic will be medium / light. I'm tempted to give it minimum ram and drive space.
Is anyone can help me how to setup sendmail ( Centos 5.2 ) as mail relay for Microsoft exchange. I will put the mail relay in DMZ and Mail server in Local Network.v
I am researching the CentOS Cluster Setup. Does anyone know of a guide on this or have a thread linked that I can look at? I want to build a small cluster and then be able to add to it as it grows. Mainly I want to have web hosts, data, and mail behind it. The DNS will probably be on there own.
I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.
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)
Postfix in Webserver is using Postfix as relay, next, Mailserver is sending emails ok when I use phpmail in any "virtual domain", but I have a few problems that I don't know how to fix...
1) If I send a phpmail from the "default domain", it is not working (no Postfix has log acitivity).
2) If I send an email using phpmail function without a from, the from will be www-data@w1.domain.com. Because I am hosting lots of virtual domains, I really need to use as "sender (From)" a mailbox named: whatever@hostedvirtualdomain.com.
I have a Fedora 10 machine that I want to setup to send email. However I don't want it to be a full blown SMTP setup.What I am looking to achieve is when something sends email from the local machine (e.g. from cron) to an address I want it to use an MTA on the local machine which will then connect to, and authenticate with, my e-mail providers SMTP server this will then take care of actually sending the e-mail.I don't want, or need, to setup a full blown SMTP service (i.e. only the local machine should be able to use it) so sendmail seems a bit over the top for my needs. Nor do I want to mess about with MX records (am I right in thinking this will mean I have to manage all mail for my domain?).
Iam using merak mail server.I would like to setup default and common email signatures and some contents in all of the users mailbox.How to setup in the server?.
I'm trying to setup RAID 1 on a CentOS 5 server for a zimbra email server.I get a partion schema error. Can I do this?The server is a HP Proliant ML150 G3 server with two 80GB HDD.
We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
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.
Ok I have 5 virtual hosts on one IP but only 1 domain (forwardconference.org) will be sending emails out to people....confirmations and such. The other sites may send out some emails...like back to my personal email address not hosted on this server. That works. But to people on like aol or yahoo or hotmail....it doesnt
Problem is, most people are not getting the emails. Mailq reports them being deffered for some reason. I'm having our ISP setup a PTR to forwardconference.org....does this mean all my emails from either of the sites....even if I put a different FROM: address in the php mail script...will come from [URL]? Or should I just setup my server as its own SMTP server?
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.
i have successfully done the setup of postfix and dovecot on this link [URL]I run Cent OS on top of window 7 via VM Player,i want to access mailbox from windows 7 using email client like Thunderbird and Outlook. What setting i need to do in my mail server ?
I am using Postfix on CentOS to send mail through a relayhost. The mail sends fine, but on certain clients such as the mail client on the iPhone or Windows Live Mail, the message is received with '(No Sender)' in the sender field. The Apple Mail client on the iMac works just fine.
Here is the PHP code I am using to send the mail code...
Wondering if there is a configuration setting in /etc/postfix/main.cf I can use to fix this problem. I have scoured the help files but have come up empty.
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only.I had follow this how-to http://www.linuxmail.info/squirrelma...o-in-centos-5/ and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works.I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, i install VM player on it and run CentOS inside the VM Player.I want to do testing on Windows 7 side by installing Thunderbird email client program, i want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How ?
Do i have to do any other configuration on CentOS ? any DNS ? port number for IMAP,POP3 or SMTP ?
Our mail server keeps on hanging after a while. This happened after there was a breakdown in electricity supply and the server room air conditioners stopped working for almost half a day. We are not sure whether this is a server hardware problem or a coincidence with a break-in attempt or malware activity.
Following are the message from the server log code...
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 would like to set up a mail and instant messaging server running on squeeze.It will be running on a 1ghz celeron (pentium 3 era) with 1gb ram and 10gb hdd (I'm assuming these are high enough specs) It will have less than 10 accounts and probably no webserver (not sure if good idea). I am also unsure of what IM protocols would be best for this. I would prefer to do all this from the command line if possible (so long as it's not too hard) and preferably from a remote machine (so SSH?) I prefer IMAP if possible but pop3 and smtp are also fine. I would also like to be able to connect remotely with encryption (not a big requirement -just a nice feature)
