If I copy my droplet to a new one, what happens to my mail server settings?

Firstly, can I say that Digital Ocean has always been very helpful to me. Secondly, please be advised that my IT knowledge is at a dangerous level. This means I am totally confident that I can blow my 10 year old website up with one wrong move. Yikes!

While the website is free for the user, it’s cost me a fortune. I just wanted to help people brew beer but the last years seem to be spent just solving IT stuff :)

I’m working on a complete site rejuvenation and name change. About a year ago, DI dropped their prices a lot and I was excited about this as I thought I’d be able to buy several droplets and use them for testing, backups etc but…

My current droplet also acts as a mail server. I can’t remember how I even managed to set it up but it was incredibly difficult. (I remember weeks of study and having to write to Google, Microsoft and many other organisations to ensure my mail server was “trusted.”)

Atm, my droplet costs about $20 per month but with the new pricing, I could run three or four which would be so helpful.

From what I have studied though, if I just copied my current droplet to a new one, I would lose all my mail server settings (MTX records from memory?) which would mean I’d lose all the “trust” I’ve built up as a mail server.

Is there some way around this or should I ask DI directly for help?

Many thanks, Pat

P.S. Please accept my apologies for my atrocious lack of specialised IT knowledge. In the last years I’ve, unwittingly, had to self-learn a lot of IT stuff across a huge range of specialties - way to hard for one person. If I can create more droplets, I’ll be able to get some help without fear of blowing the current site up.
