how to go about switching mail servers.
mail.domain.com is used as the MX record and is where users point their mail clients for POP/IMAP access. I'm obviously going to be relocating the record to a new IP.
My questions are:
In the interim period, can I have exim 'redirect' POP/IMAP connections to the new IP (for users), and can I have exim relay/forward (not sure on the term in this case) mail received from old DNS caches to the new mailserver IP?
I am moving a couple clients over to my server tonight, but I wanted to make sure I took steps that they don't miss any e-mail that might be sent. It is my understanding that say the switch happens tonight at midnight. Any e-mails they did not download from the old server will be stuck on there correct? Because they would come in the next morning and hit outlook and download just from the new server?
Is there a set protocol for doing this move with minimal client hic-ups?
i've moved servers (joomla site).
only problem is that I'm on limited bandwidth internet, and i still have some really large files on the old server. can i transfer them to the new server without re-uploading them?
Im about to move servers as my old one was running so slow, but im worried about losing important emails in the change over. I remember reading something ages ago that said if you change a specific setting on the old server 24 hours before switching then when you switch the DNS will route to the new server quicker.
way, AVOID Stiletto Media web hosting. There support is useless and they have regular downtime, like 8-24 hours a WEEK. The servers are also incredibly slow. Dreamweaver constantly times out when trying to connect!)
I want to move around 20Gb of files from dreamhost hosting account with custom control panel to a cpanel VPS in another datacenter.
Is there anyway of transferring all the files to new host without downloading and uploading to the new host. Coz i have normal DSL and 20 GB downloading and uploading can take years.
There are some forum files CHMOD to specific values if you can transfer them without resetting them in new host also cool.
Can anyone give help? both servers have SSH and FTP
I get to know you can rar them and Wget it from the VPS.
But thats file by file.
Is there a way to move complete directory with wget command?
I have web site on one shared hosting. Now I want to move to another provider. However on first one I have around 500MB of emails which I would like to move also, because I only use web mail.
I found some instructions that I can copy Qmail's folders and emails and then restore them, but since this is something that providers will charge me for ($80 just for backup), I'm looking for another solution.
I was thinking that since both servers allow IMAP access, I could simply log in in one and another and then copy emails between folders.
- Would this work?
- When I log in with Microsoft Outlook, I only see "Inbox". I don't see "Sent" or other folders which I also have to copy. How to work around this?
Long story short, my web host is unreliable and after a down period of 3 days - I want to move my website to a new dedicated server.
Old Server - Fedora Core 6 with Plesk 8.1 (64 bit)
New Server - Cent OS 5 with Plesk 8.0 (Still to confirm version)
My problem is how to transfer all data from one server to the other? The most important item to backup are the emails, and the rest I can do manually. Ideally I would want to backup the entire server in a one, and upload it to the new one but I doubt that will be possible.
I'm going to start moving all my resellers from one dedicated server to another.
I'm going to do it like this:
Suspend their account in whm, but instead of it saying account suspended, it will be changed to something such as "Account Transfer in Progress". This will prevent changes to db's, files etc which could be lost during the transfer.
Once all accounts have been transferred I will change nameserver IP's to new server. They can then use their accounts as normal on new server.
What I want to know is:
What will happen to emails that are sent while the accounts are suspended, will they bounce?
how I could transfer the accounts (150-200) with minimal downtime, I would be interested.
Does anyone have any suggestions on how you would physically move servers from one datacenter to another with minimal downtime?
The IP address is going to change, so the server will go off and then come back online with a new ip.
Just how much downtime is acceptable before customers get annoyed?
When is the best time to do it?
Move them yourself or courier or any other ways?
I currently have 2 DNS Servers with CPanel-DNSOnly Installed, used with CPanel's DNS Clustering options to store dns entries from CPanel web servers.
I am looking to buy a Windows server(probably with plesk), which i think will not support current CPanel DNSOnly Servers ?
What i need to do is
1. Migrate CPanelDNSOnly(which uses BIND) to TinyDNS on both servers
2. with a simple web-based management of dns entries(to give control to my clients, like DomainDNS.com)
3. and auto updating of DNS Entires from other CPanel and Windows servers, without conflicting same domain records from different servers (which i think can be solved by updating entires by Latest Modified date/time).
I am not an expert, and not really sure if i will be able to setup everything myself. here i need your help, guidence, and links to tutorials and help... From where should I start? What and How should I do? Should I consider hiring a System admin? any sugestions or reference for such admins?
I have a question regarding status pages. Whilst setting up a new website, upgrading forum scripts etc what is the best way to redirect users?
I would like myself and one other person to have access to run the tasks, however I would like to redirect visitors to the website to a standby page whilst we are doing this.
What is the best method? .htaccess? IP based?
We recently moved all our hosting accounts from our servers to new servers with a new host. In the process of this move, after moving all the domains and setting the nameserver ips to the new ips, none of the sites are pulling up. I changed the ip for all nameservers to the ones provided to me by the new host but we cannot figure out why the sites are not pulling up, he says everything on his end is fine? Talking about 100+ clients who have been down for over a day now after changing the nameservers and cannot figure out whats going on. All we did was set the ips on my current nameservers to the new ips below.
Now they are claiming they can bring the sites up, but none of the clients I have talked to can bring them up. Also I cannot bring up any domains or ping them from my home or work.
Example domains that are not working that were moved:
bluetongueskinks.net
pokemongamesnow.com
The 204.16.247.150/~username works fine.
See 204.16.247.150/~pokemon
The accounts transferred over fine in WHM. We were using a dns redirect in WHM on the old server before changing nameservers to make sure it pulled them all up fine.
ips for the nameservers 204.16.247.150 and 204.16.244.150.
I'm moving a large, 4 gig site between 2 servers (both have cpanel... if that's an option). Is there a way to do it quickly and correctly? How would I transfer such a large site?
View 3 Replies View RelatedWe have a business website that is currently hosted on Windows. There is one of those generic control panels and we are now moving to Linux hosting also with a generic control panel.
All the staff has email and large email boxes. How can we move the mail from the old Windows host to the new Linux host. Both setups have dedicated IP's and yes they are on SHARED HOSTING so the tricks to change the email would be limited.
We send mail to another servers but we cant recieve mails another servers. We can't recieve with webmail and outlook.
I look logs but there is no error and our ip is not in blacklist.
there is the error in our server

I want to migrate a customer from his current host to a new one. The website is the easy part, site migrations are not a problem for me.
The hard part is the email. I can re-create the account, but what about the messages stored in the old server? How do I move them? How do I get all the stuff and copy it into a shared account controlled by CPanel? I think the other server uses Plesk, which uses to be a pain in the ***.
I'm in the process of moving some websites between hosts... from Dreamhost to a VPS.
Basically I want to make sure that no emails get lost in the transfer, as it's possible some people haven't collected their emails. I'm only talking about 5 or 6 sites here with about 15 mailboxes in total.
I have pop3 set up on the VPS with exim4 and courier using Maildir's. I have imap/pop3 access to emails on dreamhost and all my clients only use pop3.
Dreamhost doesn't provide direct access to the Maildir's of users, so I was planning on using offlineimap to save a copy of each mailbox and move it into the Maildir of the user on the VPS. I.e. move the contents of INBOX/new into user/Maildir/new etc. I'll do this once the dns settings have propogated so I can be sure to have every single email.
Does this sound reasonable? Is anything likely to break? Will any email clients break with any of these transferred emails? I tried it with a test account and it seemed OK, but I would like an experts opinion on whether or not this is the best way of achieving what I'm trying to do
i enter my ip in dnsstuff.com for see spam my mail
because if i send one e-mail of my server to gmail go to spam

PTR MISSING! 111.1.1.1.1.1 has no reverse DNS entry; some mail servers may not accept your mail. 86400 seconds 0 ms
What means?
means my ip server is in blac list?
I have configured my yahoo domain to use Leaseweb shared Linux hosting by changing my A records to my hosting IP. When I check my yahoo domain control panel I see,
Type: >>>>>>>>>>>>> Source: >>>>>>>>>>>>> Destination:
CNAME Record>>>>>>>>>>>>>mail.mydomain.com>>>>>>>>>>>Yahoo! Hostname
Problem
All my email addresses that I created from Leaseweb plesk control panel can not receive any emails (test emails bounce back with a failure notice)
I think I have to change the above CNAME record in yahoo domain control panel to leaseweb mail servers.
For mail server admins, do you enforce PTR (reverse dns checks) on incoming mail? All hosts know to have rDNS set on their mail IPs to ensure free-flowing outbound mail but do you also enforce the check on inbound.
And does anyone know of somewhere that shows stats on the state of net and what perecentage use PTR checks etc?
I have 2 servers 1 US and 1 UK.
What I wanna do is synchronize both of them using rsync. Once they've got synchronized, the UK will be the primary server and US will be secondary, in case the UK goes down.
my questions are
1. Is it possible that when the UK goes down, the A records for domain.com automatically switches to the US server so it can take over while UK is down.
ie. UK ip 112.113.114.1
US ip 222.111.444.5
domain.com A records = UK ip when up... but when UK is down, A records automatically changes to US ip.
2. And when the UK server goes up again, whatever changes made to US server will be pushed to UK. May it be files, accounts or e-mails.
I.E.
UK and US are synchronized every 30mins. UK and US both have e-mails 1-10.
Just before the sync time, UK server received an e-mail 11-15 then goes down. So the US Server will take over but do not have 11-15 mails, since it was received before sync time. During the UK downtime, US server received e-mails 16-20.
When the UK server goes up, will it be possible to sync both servers that both of them will have the e-mails 1-20?
I hope you get my point...
If these are not feasible, what can you advice as an alternative solution. All I want is to avoid downtimes, especially with mails as the business relies on this.
i'm running a forum and a few other things on a futurehosting VPS plan which is running centos.
we changed to futurehosting because our shared hosting was definately not coping with it, so we had to make a quick changeover... unfortunately i dont have too much experience with setting up mailservers in linux(which seems to be a massive complicated mess involving a million different services).
i'm wondering if anyone knows any guides to setting up a mail server + have a managable web interface to add user accounts/setup forwarding rules and such that works well with centos?
or better yet, is futurehosting capable of doing it for me
I have a virtual dedicated server with GoDaddy. I don't know to much about managing a server, but have been doing ok for the last 5 months or so (so please make any explainations VERY simple)
I run several pretty heavy traffic sites, and the scripts on the sites send out automatic notifications to the user base that has requested such notifications (new responses, new listings etc..) and in the past few days NONE of those emails are making it through.
The mail just DISAPPEARS! I'm not getting any bounced email, the mail queue manager has only the same spam as not being allowed through, and I have restarted exim, GoDaddy also says that mail IS being sent from the server, they just can't explain why it isn't being delivered, and I'm not going over the max amount I can send daily.
I have NO clue what is going on and ANY help is REALLY appreciated!
Also, the forwarders are still working (mail sent to user@domain.com still gets successfully forwarded to the correct email address)
