Hi,
After lot of postponements, we finally took a Level 6 VPS
We planned to move 2 of our 7 yr old Silver Resller accounts to the VPS
One of our reseller domains exlsystems.com, had private name servers, and so it looked very simple to transfer this one, with the name, same private DNS Servers ns1.exlsystems.com and ns2.exlsystems.com, and all the accounts under it to the VPS.
Over the last weekend we got all the domains under this shifted to the new vps exl.exlsystems.com
After that we simply changed the IP addresses of our name servers at the domain registrar. The client domains did not have to make any changes, as their name servers remained the same.
The second reseller domain does not have private DNS and the client domains will have to switch DNS when we move their accounts to the VPS. We had thought of moving those accounts over the next weekend, but we are not sure, as we are just trying to resolve the problems with our VPS.
All very well till now.
Now the problems start.
Email addresses for our client domains started getting lots of bounce mails.
We promptly created a Trouble ticket No FBJ-14954259, and it's in it's 3rd day today.
The main mail errors are happening from 2 domains were as follows :
1. All cluster4.us.messagelabs.com and all other messagelabs.com hosts.
Error : cluster4.us.messagelabs.com [216.82.253.243]: 501 Connection rejected by policy [7.7] 17108
These hosts reject connections even before the helo. They will not accept any telnet session from our server.
We wrote to support@messagelabs.com and they are of no help, and tell us that only their client domains can create support tickets.
2. All messaging.microsoft.com hosts
Error : mail.global.frontbridge.com [65.55.88.22]: 550 5.7.1 Service unavailable; Client host [174.122.111.190] blocked using Blocklist 3, mail from IP banned; To request removal from this list please forward this message to delist@messaging.microsoft.com.
We wrote to delist@messaging.microsoft.com and they wrote back saying that they have removed our IP addresses from the blocklist, and the problem will be resolved in a few hrs. Even after 24 hrs of that mail , the mails are still bouncing back.
In the meantime Admins at Hostgator recommended that reverse DNS be created for our IP Addresses, and that was done more than 24 hrs ago.
The mails still bounce.
We are on the verge of loosing some important clients because of these problems. We had we will be able to improve service by moving to the VPS, but it's been the other way round.
For 3 Days clients are not able to send messages to a number of Email addresses and they are loosing patience.
If it is a new VPS with new IP Addresses, how is it that the IP Addresses are already blocked.
The admins at hostgator tried to change the exim settings to send mail from a different IP Address (Out of the 4 we have on the VPS) but that didnt work either. Infact we are worried that since the SPF records for all domains point to the primary IP, and mail is now not going out through that, we might run into problems due to wrong SPF records. We requested hostgator admins to set exim to send mail from the primary IP again so as not to disturb the SPF settings for all domains. This request was made more than 8-9 hrs ago but we are still waiting for a reply.
Now I have the following options :
To move the Accounts back to the reseller account which is still active, and surrender the VPS in the trial period.
To wait a few more days to see if the problem can be resolved.
As a last hope I thought I will put it in the forums, incase somebody can give us some suggestions.
