I see that with 99% of hosting companies you can create your gibibyte email account (or even bigger). I have, but at one point when you have hundreds of emails, your email client gets really really slow if you use IMAP. Also, the search feature doesn’t work very well, you search something that you know should return results but you get no results… If you use POP, you don’t have these problems, but you can’t access your mails from any computer, as you download them onto your local computer (and your mailbox is empty 99% of time).
In the end, Gmail, which is free, works better than a paid mailbox from a web hosting company because your inbox pops up instantly, when you search something, you get the search results in half a second. And you can use several gigs easily, it makes no difference.
How can I use a gibibyte mailbox with thousands of mails, lots of attachments, with a fast/efficient search feature, and have it working as fast as Gmail? Is IMAP flawed? What do you think?
