Using FastMail with Apple iPhone and iPodTouch

What you need to know

The Apple iPhone and Apple iPodTouch both share a built-in email program.
The Mail applications can easily be configured to use your email account at FastMail.

Many times, the iTunes application will synchronize your email configuration automatically to your iPhone. You can also configure it manually using this guide.

In this guide, we will refer to the device as the iPhone (the setup instructions are the same for the iPodTouch).

Note: If you already know how to set up your client, and you already understand the information below, see this help page for the server information you need to set up your e-mail client. The Troubleshooting Issues section at the bottom of this page may be helpful if you have problems.

In order to use Apple iPhone with FastMail, you'll need to enter the following information:

  • username - When you signed up for FastMail, you chose a username which is also your e-mail address. You must use the full username, including the name and the domain part, which is the part after the '@' symbol. For example, a user named John Doe might have chosen a username of "johndoe@fastmail.fm". Make sure that you specify your username in lowercase only.
  • password - When you signed up for FastMail, you chose a password to go along with your username. You will need the password to access your account. The password also keeps others from being able to access your e-mail. Your password is case sensitive, so be sure that you type it in correctly. "PASS123" is different to  "pass123". Often, users forget about the CapsLock button and mistype their password.
  • incoming mail server (IMAP or POP) - This is the server that you get your e-mail from. Internet Message Access Protocol (IMAP) and Post Office Protocol (POP) are retrieval methods used to move e-mail messages from the server to your e-mail client so that you can read your messages. POP access is not available for all service levels, please check the pricing table for details. Secure Sockets Layer (SSL) is required for your protection as well. SSL keeps people from reading your e-mail as it is transmitted between the e-mail server and your computer.
  • outgoing mail server (SMTP) - This is the server that sends your e-mail. Simple Mail Transfer Protocol (SMTP) is the method that your client uses to move e-mail messages from your client to the server so that it can send your messages. The FastMail SMTP server is not available for all service levels, please check the pricing table for details. If your service level does not allow use of the FastMail SMTP server, you must use the SMTP server provided by your Internet Service Provider (ISP).

    The FastMail SMTP server requires SMTP Authentication. This keeps people who are not users of the FastMail service from using the SMTP server to send spam messages on the Internet. SSL is required for the FastMail SMTP server. If you don't use the FastMail SMTP server, you may have different options or requirements. You will need to get that information from your ISP.

Special Notes

Some other items to consider:

  • You do not necessary have to set the IMAP Prefix on the iPhone to be INBOX. For our business customers, leaving the prefix blank allows your iPhone to see any shared email folders that exist in your business.

  • If you use mostly utilize a public WiFi to access your email using your iPhone or iPod Touch, these can sometimes cause connection issues. That is due to the WiFi provider being very restrictive regarding the ports that are made available. Not to worry, you can change your email configuration to utilize our Proxy services. The proxy allows you to use IMAP over any port necessary (usually port 80 is available). You can learn more about our proxy servers here.

Replying with Multiple Personalities

FastMail has a great feature called personalities. This is especially useful if your FastMail account is receiving email for multiple aliases or domains. For example, you may have an address of joeuser@digitalintegrity.com. You would also like to reply to messages as sales@digitalintegrity.com or support@digitalintegrity.com. Personalities makes this possible.

Unfortunately, the iPhone and iPodTouch don’t make this capability easy to take advantage of.

Fortunately, this is easy to fix. The latest iPhone firmware (version 3.x) makes this even simpler due to the inclusion of the copy and paste capabilities.
Apple’s Mail.app program on the Mac has always supported this feature. In Mail.App, you simply separate all of your email addresses with a comma and they act similarly to multiple personalities.
The problem with the iPhone and iPod Touch? The keyboard is modified so that you cannot enter a comma in the email address field. Very frustrating.
There are two solutions:

  1. Create your account in Apple’s Mail.App on your Mac with the comma separating the personality email addresses. Then resync your iPhone and choose to migrate the email account information.
  2. The second (and easier solution) is to take advantage of the cut/copy/paste capability in the iPhone 3.x firmware to paste into your settings.

To fix the iPhone directly.
  1. Open Notes, create a new note. Type in your other personality’s email address , me@otherdomain.com . NOTE the comma, this is the most important part.

  2. Use the tap commands to select all and copy this information to the clipboard

  3. Open up the Settings/Mail, Contacts, Calendar application.

  4. In the IMAP Account Information Field, tap at the end of the Address field and Paste the additional email address. After you’ve done this, your Address field will look something like this: myaddress1@domaina.com, me@otherdomain.com

    Notice in the example below: joeuser@digitalintegrity.com, sales@digitalintegrity.com

You have to use this trick to get a comma into the Address entry field.

When you compose a new email on the iPhone, just click on the From option and choose the appropriate address.
