In this day and age, it really makes sense to switch from POP email to IMAP.
What’s the benefit of IMAP? Quite simply, that if you’re doing email in more than one place, it keeps it all synchronised (if you also need calendars and folders, then it’s worth considering Exchange). For me, I have email on my Android phone and in Outlook on a PC. I want them to synchronise, so I can send or receive email from either, but also have the state reflected in both. To do this, the mail is kept permanently on the server.
So, when I switched hosting to Vidahost, I decided to set up IMAP Outlook and Android. It’s quite straightforward. The main thing to remember is that mail is going to be kept for you on the server not deleted on retrieval like with POP3. So, having created an IMAP account on Outlook, I then had to copy all mail across, and then let Outlook synchronise it, which was mostly painless. And then create an account on Android to do the same thing. And that’s it. Well worth it.
