Let me expand...
I have a client who is unhappy with their current hosting situation. They want me to move their website and domain across to my hosting platform. I can do this.
However I have realised that the company has:
1) A number of existing IMAP accounts
I understand that I can use a tool like imapsync in order to transfer the mailboxes and hopefully incur only a small amount of downtime with the emails during this process. Can anyone offer any advice regarding the transfer of IMAP mailboxes from one server to another.?
2) An SMTP Relay
Another company supplies my client with an SMTP relay. I've only really just found out what this is. I understand that emails are sometimes undelivered to the client and a mail relay routes incoming mails through another (more reliable?) server in order to keep trying to resend emails so none are missed.
- Am in in for a lot of hassle moving email accounts or is this a fairly transparent process?
- What should I look out for and how can I make this hosting transfer seamless (or nearly seamless)?
- When I move the domain to my server (and the IP changes) this will interrupt the current mail relay. Will my client's emails continue to be delivered?
