This is an old post that I found on my hard drive. I’ve re-written it in more of a how-to format. Hopefully someone might find it useful as I know that it took me a lot of trial and error before I found a setup I was happy with.
The Problem
Like most people I have a number of domains that all have email accounts associated with them, a work email, a Gmail account, a desktop email client, email on my iPhone, and occasionally I need to access my email via the web. The problem is how to manage all of these accounts across multiple devices and have each device reflect the changes made on the others.
The Solution
To address this problem I use one account that acts as a hub for all of my email. I’ve chosen Gmail for this purpose as it has generous storage and good spam filtering. The first step is to set Gmail up to check all of your other email accounts, to do this go to Settings -> Accounts. As you’re setting each account up you’ll be given the option to verify each account so you can send from it. Once you’ve added all of your email accounts, and also verified them for sending, the last thing to do is to tell Gmail to automatically reply from the same address the message was sent to. This option is in the “Send mail as” section under Settings -> Accounts.
The next part of my email universe is the desktop client. I use Apple Mail, so I’ll describe how to set things up using that, but the same results can be achieved using Thunderbird. My Gmail account is set as an IMAP account and I’ve set my Sent, Spam, Trash, and Drafts folders up to use the corresponding folders of my Gmail account. This is important because when I send an email using Apple Mail I want it to go to Gmail’s Sent folder so that it’s visible via the web and also on my iPhone. To do this in Apple Mail, select the Sent folder under your Gmail account on the left and then go to “Use This Mailbox For” under the “Mailbox” menu and select “Sent”. Repeat this for Spam, Trash, and Drafts. The last thing to do in Apple Mail is to set up your additional email addresses so you can send mail from any of them. In Apple Mail you simply add them to the “Email Address” field under your Account Settings (Comma Separated). If you’re using Thunderbird you can do this by adding Identities. Both Apple Mail and Thunderbird will automatically reply from the address the message was sent to.
The final piece of the email puzzle is the iPhone. My biggest problem with the email client on the iPhone is the way that it handles multiple accounts. Fortunately our system avoids this problem as we only have to add the one Gmail account. Once you have your Gmail account set up on your iPhone it’ll keep everything synchronized. Where the system falls down slightly is the inability to send or reply from different accounts. That means that anything sent from my iPhone comes from my Gmail account. It’s the only blemish in my otherwise “perfect” email setup.
