Server :: Server Configuration For Small Office Server, Which Smtp, Pop Imap Server And Backup?
Apr 2, 2010
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I am working on linux server with below specifications.Linux EDT 2008 i686 i686 i386 GNU/LinuxWhile checking the status of the server using the command 'opmnctl status' and when server is down the output is not getting redirected to file.I m using the command as,opmnctl status > abc.txt.
i want to set up an email server both to receive and send emails. I also am on a dynamic ip scheme with my ISP. I do have a dynamic dns account with no-ip.org the Questions are:
-will somebody be able to send emails to me at the <user>@<dyndns_name>.no-ip.org email address?
-will I be able to send emails from the <user>@<dyndns_name>.no-ip.org email address?
I know i'll be able to login to accounts like gmail and yahoo and download emails from there.. but even that i don't know - even macroscopically how its done:
-is it the sendmail deamon that accepts the mail from <me>@gmail.com, <me>@yahoo.com, <me>@<dyndns_name>.no-ip.org?
-is it the sendmail deamon that does the sending of email (as well)?
-can it push emails that I want to send as <me>@gmail.com to the gmail smtp servers (and they in turn will push my email even further)?
-can it push emails from <me>@<dyndns_name>.no-ip.org to receipients? and finally,
-WILL receiving pop/imap servers allow incoming email from my server? or due to the dynamic ip they'll assume I'm a spam server?
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] 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?
I am about to set up a small office server. I want to know if it is possible to use ubuntu for file and printer sharing on a network with 9 winXP computers and three printers. The printers are all USB Compatible. There are seven winXP pro computers and two XP home.
Would it be possible to use CUPS and SAMBA for this configuration?
iam trying to sync file server data into backup server machine by command- rsync -avu path/of/data ipaddress-of-backup-server:/path/where/to/save after running it ask for root password and manually it is successful.but i want to make it automatic.for that i also tried cronjob and also generated authentication key but iam not successful in login automatically..anybody know how to authenticate root to login for storing data in backup server.
I am trying to setup a file server for a small office but have hit a couple of hurdles, is there a step by step guide how to setup a network for windows and mac computers to use it? I had setup a share etc but once I restarted the server all the files disappeared which I had in the home folder? Also when I setup users how can I use passwords that I select as everytime I set one it encrypts it and uses that instead of my one?
I recently setup an email server on Fedora Core (14). Sendmail is running and I am trying to authenticate from a client pc using imaps. I installed Cyrus-imap and it is running and listening on 993. When I try to login, it doesn't accept authentication even though I verified the user's password is correct. (tested with ssh)Is there something I have to do with Cyrus or on the server to allow connections to email? I have not used Cyrus before. I am attempting to access my mail folders via Sendmail and did not make mailboxes in Cyrus. I did allow imaps through the firewall.
I setup a qmail on a Debian 5 Lenny server with courier-imap server. I can send mails but cannot receive mails. I altered /etc/init.d/qmail as follows.
Right now i have a HP DL 180 Server with 130 Gb Hard Disk & 8 Gb ram after Raiding0+1. i want to configure Domain Controller Server for my office for 200 to 300 Users. what should the partition size must be mentioned in my 130 Gb Hard Disk, is that going to be Sufficient for ME ?
i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
my postfix to send and recive external emails, but many recive in trash folder.Other programer say me that is need some configurations in postfix with and dovecot to work, but i dont know what!This is my first time configuring a linux server at this week.
my main.conf sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
I've got an uber simple test mail script in php on my awesome new dev machine running Ubuntu:
PHP Code:
Unfortunately, something is preventing mail delivery. I can't tell from this error log whether it's the remote machine rejecting me or whether it's my machine rejecting the self-signed cert on the remote machine:
Code:
I'm wondering what I could change in my postfix configuration to remedy this problem.
I tried setting smtp_tls_security_level = may = may but this did not change anything.
I'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :
Code: relayhost = [myMailServer.localhost] smtp_sasl_auth_enable = no smtp_use_tls = no disable_dns_lookups=yes smtp_never_send_ehlo = yes code....
I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.
I have a server that runs on a static IP address with many hosting accounts. I am using the IspCP to manage the different sites. When a mail is sent, the headers include the box's own domain name: [URL]. Now [URL] is no longer active, so if an email from another account: [URL] sends mail, there is possibility that this mail is rejected by the receiver, if the receiver system does rDNS.
The receiving server will check the headers smtp sent from [URL] and come up as a fake, because [URL] is no longer registered. I wonder if there is a way to make the smtp headers reflect only the domain name that sent the mail. Then if joe sends mail, the server should replace[URL] with [URL]. If this is possible, then users that send mail will not get bounced because the rDNS lookup will map [URL] to the ip and the mail will be accepted.
we have qmail server installed on rhl 9. it was working perfectly fine for last 1 year. suddenly it stopped accepting emails from internet. when i telnet on port 25 it takes about 90 secs to show the SMTP ready state.I have tried many things
1. stopped Reverse DNS Lookup by adding -H to qmail-smtpd/run file 2. stopped spamassing and AV 3. reverified DNS server settings in resolv.conf 4. dig is resolving dns query properly.
i also observed that when i do telnet to telnet localhost 25 response is very quick
but when i do telnet local_server_IP_address 25 it takes aprx 90 secs to show me SMTP ready messege.
can someone shed some light on this as what should i do next to rectify this problem..
I come back to everybody cause I don't find an explicit how to do this!In our internal network, I've created an email server with Postfix and Dovecot. (Just for internal domain, no needed to go outside)
But I've some server which use linux too. All are on CentOS 5.5.I would like to configure these servers to use my internal mail server for send email, and not configure sendmail or postfix on each server.
What I've to do exactly on each servers to use it? I search on the web but I don't find something very explicit
I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.
I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:
Code:
main.cf:
#See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default
I run my own mail server. There's only one part that isn't working and I can't seem to figure out why: sending mail from a client - in this case, Thunderbird.
I can send mail off-server just fine if I log in via telnet. I can receive email just fine with Thunderbird.
Last weekend i've set up my first headless ubuntu home file server and torrent downloader with ubuntu 9.10.Very cool but CPU is way too fast for a home server: P4 HT 2.8Ghz, unfortunatly it has only 256Mb of ram, so no X server and no VNC (old HP office pc) At the moment memory usage is only 40Mb without X server. Besides SSH works just fine Few questions i can't seem to find answers to on google:What is a good CL network monitoring program?mething similar to htopUbuntu 9.10 has a lot, about 20-30, console-kit deamon instanses running after boot each using some memory that i can't spare.
I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.
How do I tell php to send an email with mail() using an external mail server?
The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.
I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.
I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?
is qmail server running in the secondary office and it was working fine. yesterday qmail suffered some problem.i came to know about the problem today.now after troubleshooting and looking into the server, the qmailclt stat commands shows that all services are working and there is nothing going crazy in the server. The maillog is showing errors which i am pasting here for the convienance.
I have been having trouble figuring this out. I have a machine running CentOS 5 and I want to setup an SMTP server behind a router on a home broadband connection. I've read many guides but nothing too specific as to what I need to do. I want to use either sendmail or postfix, but I don't know if I should purchase an SMTP relay. If anyone could point me in the right direction it would be great. I also have bought a domain name that I want to use, but I just cant put all these pieces together as of right now.
I'm trying to set up a small web server with php and sqlite support. I installed lighttpd, php5, php-sqlite3 and php5-sqlite3. Then, I enabled sqlite and pdo extensions in php.ini: extension=pdo.so extension=sqlite.so extension=pdo_sqlite.so
However, when I try to open a SQLite3 database from php: $database = new SQLiteDatabase($myDB, 666, $error); I get the following exception: SQLiteDatabase::__construct() [sqlitedatabase.--construct]: file is encrypted or is not a database
Some readings in the net make me think that my php settings are not compatible with SQLite3 databases. Is anyone successfully working with SQLite3 databases from PHP5 under Debian? Have you any recommendations? Should I rebuild php maybe?
I currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.
