Thanks for the information, very valuable!
What config should I use?
Larry suggested 1GB, is that enough for iRedMail or maybe 512 will do?
What for the wordpress droplet? 512, 1GB or higher?
And for the fun of it, let's say I make 3 droplets, 1 for the db too, what about that one?
I suppose you mean the website databases, not the mail db?
(and how do I connect the wordpress to the mysql droplet, probably just ip and username based?)
Looking forward to your comments!
