On Changing Mail Servers

My personal, non-blog-related domain has used Google Apps for email for years. In essence, one gets all the benefits of Google Mail (excellent spam filtering, IMAP/POP/SMTP, huge amount of storage, reliable infrastructure, etc.), but for one’s own domain. Very handy.
One of the advantages of having one’s own domain is that one is not bound to a specific email provider; one can change the back-end provider relatively easily and with essentially no disruption. Over the last 11 years, my personal domain has had probably half a dozen providers handling email, with Google Apps providing service for about the last four years.
While I’ve been quite satisfied with Google Apps (( Although there are a few quirks when using IMAP due to the fact that Gmail uses “labels” instead of “folders”, they’re minor and easily adapted to. )), I always like to check out alternatives at intervals, much like I do with car insurance.
Fortunately, Google makes moving away from their services extremely easy: it’s trivial to move mail to the new server by IMAP, and a few simple changes to my DNS records now direct mail to the new server. Everything was done with about 5 minutes of work.
There’s two quirks with moving away from Google Mail, though.
The first is that Google Mail is primarily web-based, and offers IMAP/POP service as a feature, while the new service is primarily IMAP/POP with webmail as a feature, and so their webmail is pretty basic.
The second is that Google has excellent spam filtering, mostly based on the input of its brazillions of users marking messages as spam or not spam. The filtering takes place on the server side, which keeps spam levels in one’s inbox to a minimum regardless of whether one uses webmail or IMAP/POP. Marking messages as spam or not spam is trivial and totally in-band (click a button on the webmail interface, move the message to an IMAP folder if using a client).
The new provider offers some server-side filtering, but it’s nowhere near as good as Google’s, and using the server-side filtering requires identifying spam or non-spam via out-of-bound methods (clicking a link in the email, which opens a browser window) which is a bit tedious. I can do better filtering on the client side, but that means that accessing my email with the webmail interface (which doesn’t have the filtering ability of my mail client) results in a massive amount of spam polluting the folder.
Slightly frustrating, to say the least.
I’ll give this other provider a few more days to see if their spam filtering can adapt to deal with the onslaught, but for my purposes (mostly webmail, with occasional IMAP use), Google Apps’ service appears to be better. However, in the event that Google turns to the dark side, it’s good to know there’s options.
