#Frequently Asked Questions (FAQ)

How do I prevent K-9 Mail from reporting unread messages I already read from my desktop? I'm using POP3.

This is a POP3 limitation: that protocol doesn't report/support READ/UNREAD status. IMAP addresses this limitation.

How do I change my Signature?

Do the following to replace default signature in K-9 with your personal signature for any email account or stop K-9 default signature for that particular account:

Open K-9, select email account in which you wish to create a signature. Key Sequence: Menu/Settings/Account Settings/Sending Mail/Composition Defaults

In this dialog, you can enter Your Name, Your Email Address, Bcc all messages to, CHECK (or uncheck) USE SIGNATURE, enter your signature using correct syntax of top line of signature with -- followed by a line break, and enter your desired signature. Choose radio button to place Signature position before or after quoted text.

How can I configure the Archive, Drafts, Sent, Spam and Trash folders?

"Account settings" (via long click or Menu) > "Folders" ("Incoming server" in pre-3.400 versions)

How can I attach *.xyz files?

K-9 Mail uses the standard Android way to inherit external app features (Intents); you need a file manager application in order to choose any file.

Compatible file managers:

• OI File Manager (open source)

Why aren't my settings saved?

Please use the Back key to leave all settings screens in order to trigger settings save.

K-9 is taking ages to fetch messages, help!

Some device have very inefficient storage. Try switching storage (3.400+ only).

Why K-9 is using so much bandwidth to sync my POP mail?

K-9 normally doesn't take much bandwidth. It is comparable to other Android mail applications such as GMail. However, there may be some situations where K-9 can consume up to 150k of bandwidth everytime an account is refreshed.

This normally happen when you have a POP account that has a huge inbox folder. If you have a inbox of about 2500 messages in it, it would generate data exchange between K-9 and the POP server in the order of 120k per refresh query.

To prevent that to happen, you simply have to move all these messages in another folder in your account. We don't recommand to keep all your incoming messages into the inbox of your POP account.
