Server :: Mail Server Migration - How To Deliver Locally AND Forward Mail To New Server
Jan 21, 2011
Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.
Is there an open source application that can download e-mails from a generic POP mail server, keep a copy of the mails locally and then deliver copies to multiple accounts on a LAN? I have a friend who uses a group e-mail account, and more than one person is always hooked onto that account. The problem is they cannot leave e-mail on the server, as it eats out their webhosting space, but if someone downloads a message in Outlook, the other users do not see that message.
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 was asking how to build a CentOS Exim mail server, & gaurantee that all mail messages will be delivered to hotmail inbox ??hotmail said that it will only accept 500 simultanuos connections (=500 messages) to its mail servers from only one IP address, so is there an exim options that i can use to limit messages that sent through the mail server to hotmail to be sent as 500 messages then send another 500 & so on
i have configured sendmail server in my lan and it is working fine for me.but there is one little problem for me. i want mails send sunita should be received by vinita.sunita and vinita both are normal users on same pc.
for this i made entry in Code: /etc/aliases sunita: vinita
I have a friend that want to migrate his server to a open source mail system. Currently, he's using a system using Maildir. So I decided to use qmail since it has support for Maildir and it has pop3 capability. Courier-imap is the one I'll be using for IMAP. My concern is webmail. Can anyone suggest a webmail that will run using Maildir format and has addressbook and calendar feature. I'll be using a single server only. Please exclude Squirrelmail from the list.

I installed sendmail in RHEL5.4 with TrendMicro Spam scan engine. The configuration like sendmail should forward all the mails to scan engine after scanning it will deliver it to the mail domains. same way all the mails coming from external servers are scanned and the delivered to local box. My problem is when i sent mail for local users its delivered locally. but when i sending mail for external like yahoo its going through scan engine. I added the smarthost in sendmail.mc file also.
I have a problem relate to posttfix.I want to mirgare postfix mail server to exchange 2010 mail server but I can't do it,u can help me.You can show me have to do configure postfix and exchange how to?
How do I make a local mail server that itself is a client to a WAN mail server.I want the local mail server to query new mail every 30 minutes from the WAN server.
There is an requirement, intranet people they may not have internet access but they want to send mail to external domain(internet),but in that intranet network one machine can have internet access. Is there any solution for this requirement.
I vae Ubuntu, postfix. I need to forward e-mail based on sender. Can I do it with .forward ?
E-mail that comes from user@yahoo.com destined to user@mydomain.com to be forwarded to user@gmail.com. Other e-mail that comes from any addresse must not be forwarded.
im unable to forward a mail with attachment my problem is as below cat /root/data|mail -s "subject" [URL] its not forwarding mail and not throwing any error my attached file is more than 100MB ,will any one me with correct syntax how much length of file can be attached maximum i also tried like this mail -s "subject" [URL] < /root/data its also not working
I want to setup a mail virtualserver in apache so that a mail. subdomain whats pointed to the box will automatically goto my roundcube install. i have all of the document root stuff working, however, mail.* doesnt work for a server name.
I wish to intercept/forward emails that is sent to one user on multi user mail server.I only want email from one specific address or group,to be redirected and it will be redirected to another user on same server.The email should not arrive in original users inbox.".forward" file can not give me such solution,because ".forward" file will forward all mails to another specific mail id,which i don't want. I want only specific users mails onto another local user.Is this possible in sendmail?Anybody have clear idea of "virtusetable" & "aliases" file?
I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.
After that I ran the same command with the verbose option:
/usr/sbin/sendmail -v root <prueba.txt
And this is the output:
root... Connecting to [127.0.0.1] via relay...
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600 >>> EHLO localhost.localdomain 250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES

For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?
I was using an email server from Icewarp, Merak Mail server V8.0.3 with a keygen for total full free use... I liked this server package... as everything is in there I need and it is controllable from a single window. Now I am planning to move to Linux... They have a Linux version, but not stable and expensive. Is there any thing almost free/less expensive (Specially they need yearly payment for upgrade of even the anti virus and anti spam)?
I need a almost same thing (except of the ftp and VoIP) like Merak (because that I really liked for ease of administration) in Linux? Like a Qmail with real strong Anti Virus and Anti Spam, with unlimited domain and user+autoresponder, mailing list, etc all but controllable from one single GUI?
I cannot get exim4 to actually deliver any "local delivery only; not on a network".But whatever I do in the config, all mail gets frozen with entries in the log file like:"root@empty R=nonlocal: Mailing to remote domains not supported"Maybe the problem is that there is no fqdn for the computer (and will never be). How can I enable local mail delivery?
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).
I have installed F11 on my server bythis article! I have problem with certificatewhen I connectin from clients computers to my mail server for reciving mail! I have warning like this
I have set up postfix and dovecot as per the Ubuntu anual and appear to have a functioning mail server.Using the sendmail command I can send mail and I receive mail in ~/Maildir. Using Thunderbird I can read any mails received but I can't send any mail from Thunderbird. I have tried with both STARTTLS and SSL/TLS and whilst I get the prompt for a password I keep getting the message my password for my server is wrong.I have ports 25, 465, 587 and 993. Is that all the right ports?When I ping my domain name it resolves to my router name whereas I believe it should resolve to my IP. Could there be a problem with my host file? I've had a play but to no avail.Here's the error in mail.log.
Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.
A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.
A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:
Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:
CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server
I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...
I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?
I have setup a postfix mailserver and it seems to be working ok, we are only using this to relay mail to our forum users. Its not being used to recieve any email only send them out to the internet.
What is the difference between the mail.log and mail.info files? Can I turn one or both off? I see alot of messages like...
Just wondering what this string of log entries means? Also I am getting duplicates in the syslog file as well.

Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
I'm running SUSE linux Server version 11. I want to configure mail server with postfix & cyrus-imap. For that, i have read many documents in Internet by i met issues. I'm running DNS in this server & it's ok Now I cannont send mail through command line.
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?
