Welcome

==================================================
 | 
			
		||||
 | 
			
		||||
OfflineIMAP is a tool to simplify your e-mail reading.  With
 | 
			
		||||
OfflimeIMAP, you can:
 | 
			
		||||
 | 
			
		||||
 * Read the same mailbox from multiple computers, and have your
 | 
			
		||||
   changes (deletions, etc.) be automatically reflected on
 | 
			
		||||
   all computers
 | 
			
		||||
 | 
			
		||||
 * Use various mail clients to read a single mail box
 | 
			
		||||
 | 
			
		||||
 * Read mail while offline (on a laptop) and have all changes
 | 
			
		||||
   synchronized when you get connected again
 | 
			
		||||
 | 
			
		||||
 * Read IMAP mail with mail readers that do not support IMAP
 | 
			
		||||
 | 
			
		||||
 * Use SSL (secure connections) to read IMAP mail even if you reader
 | 
			
		||||
   doesn't support SSL
 | 
			
		||||
 | 
			
		||||
 * Synchronize your mail using a completely safe and fault-tolerant
 | 
			
		||||
   algorithm.  (At least I think it is!)
 | 
			
		||||
 | 
			
		||||
In short, OfflineIMAP is a tool to let you read mail how YOU want to.
 | 
			
		||||
 |

==================================================
 | 
			
		||||
Requirements
 | 
			
		||||
==================================================
 | 
			
		||||
 | 
			
		||||
To use OfflineIMAP, you must:
 | 
			
		||||
 | 
			
		||||
1. Have your mail delivered to a server that supports IMAP
 | 
			
		||||
 | 
			
		||||
2. Have Python 2.2 or above installed
 | 
			
		||||
 | 
			
		||||
3. Have a mail reader that supports Maildirs (most modern ones do)
 | 
			
		||||
 | 
			
		||||
These requirements are easy to meet, and most people will have met
 | 
			
		||||
them already without even being aware of it.
 | 
			
		||||
 | 
			
		||||
If you do not have Python already, check your operating system vendor
 | 
			
		||||
or download it from http://www.python.org/
 | 
			
		||||
 | 
			
		||||
==================================================
 | 
			
		||||
Installation
 | 
			
		||||
==================================================
 | 
			
		||||
 | 
			
		||||
Basic installation for a single user requires only these steps:
 | 
			
		||||
 | 
			
		||||
1. Copy offlineimap.conf to ~/.offlineimaprc and edit that file
 | 
			
		||||
   for your accounts.  Full instructions are in it.
 | 
			
		||||
 | 
			
		||||
2. Make the directory that you will store your folders in.
 | 
			
		||||
   (~/Test in the example)
 | 
			
		||||
 | 
			
		||||
You can then just run "python2.2 offlineimap.py" to synchronize your
 | 
			
		||||
mail.
 | 
			
		||||
 | 
			
		||||
------------------------------
 | 
			
		||||
Systemwide
 | 
			
		||||
 | 
			
		||||
If you wish to install OfflineIMAP for all users on your system:
 | 
			
		||||
 | 
			
		||||
1. Either install the Debian package or run "python2.2 setup.py" and
 | 
			
		||||
   follow the prompts
 | 
			
		||||
 | 
			
		||||
2. Advise users to perform steps 1 and 2 above
 | 
			
		||||
 | 
			
		||||
3. Run OfflineIMAP by typing "offlineimap"
 | 
			
		||||
 | 
			
		||||
That's it!

Frequently Asked Questions
 | 
			
		||||
==================================================
 | 
			
		||||
 | 
			
		||||
Q. I get a message saying "UID validity problem for folder; skipping".
 | 
			
		||||
What does this mean and how do I fix it?
 | 
			
		||||
 | 
			
		||||
A. IMAP servers use a unique ID (UID) to refer to a specific message.
 | 
			
		||||
This number is guaranteed to be unique to a particular message
 | 
			
		||||
FOREVER.  No other message in the same folder will ever get the same
 | 
			
		||||
UID.  UIDs are an integral part of OfflineIMAP's synchronization
 | 
			
		||||
scheme; they are used to match up messages on your computer to
 | 
			
		||||
messages on the server.
 | 
			
		||||
 | 
			
		||||
Sometimes, the UIDs on the server might get reset.  Usually this will
 | 
			
		||||
happen if you delete and then recreate a folder.  When you create a
 | 
			
		||||
folder, the server will often start the UID back from 1.  But
 | 
			
		||||
OfflineIMAP might still have the UIDs from the previous folder by the
 | 
			
		||||
same name stored.  OfflineIMAP will detect this condition and skip the
 | 
			
		||||
folder.  This is GOOD, because it prevents data loss.
 | 
			
		||||
 | 
			
		||||
You can fix it by removing your local folder and cache data.  For
 | 
			
		||||
instance, if your folders are under ~/Folders and the folder with the
 | 
			
		||||
problem is INBOX, you'd type this:
 | 
			
		||||
 | 
			
		||||
rm -r ~/Folders/INBOX
 | 
			
		||||
rm ~/.offlineimap/AccountName/INBOX
 | 
			
		||||
 | 
			
		||||
(replacing AccountName with the account name as specified in
 | 
			
		||||
~/.offlineimaprc)
 | 
			
		||||
 | 
			
		||||
Next time you run OfflineIMAP, it will re-download the folder with the
 | 
			
		||||
new UIDs.  Note that the procedure specified above will lose any local
 | 
			
		||||
changes made to the folder.
 | 
			
		||||
 | 
			
		||||
Some IMAP servers are broken and do not support UIDs properly.  If you
 | 
			
		||||
continue to get this error for all your folders even after performing
 | 
			
		||||
the above procedure, it is likely that your IMAP server falls into
 | 
			
		||||
this category.  OfflineIMAP is incompatible with such servers.  Using
 | 
			
		||||
OfflineIMAP with them will not destroy any mail, but at the same time,
 | 
			
		||||
it will not actually synchronize it either.  (OfflineIMAP will detect
 | 
			
		||||
this condition and abort prior to synchronization)
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. What platforms does OfflineIMAP run on?
 | 
			
		||||
 | 
			
		||||
A. It should run on most platforms supported by Python, which are
 | 
			
		||||
quite a few.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. I'm using Mutt.  Other IMAP synchronization programs require me to
 | 
			
		||||
"set maildir_trash=yes".  Do I need to do that with OfflineIMAP?
 | 
			
		||||
 | 
			
		||||
A. No.  OfflineIMAP is smart enough to figure out message deletion
 | 
			
		||||
without this extra crutch.  You'll get the best results if you don't
 | 
			
		||||
use that setting, in fact.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. How do I specify the names of my folders?
 | 
			
		||||
 | 
			
		||||
A. You do not need to.  OfflineIMAP is smart enough to automatically
 | 
			
		||||
figure out what folders are present on the IMAP server and synchronize
 | 
			
		||||
them.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. How can I prevent certain folders from being synced?
 | 
			
		||||
 | 
			
		||||
A. This feature will be introduced in a future version of OfflineIMAP.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. How can I add or delete a folder?
 | 
			
		||||
 | 
			
		||||
A. OfflineIMAP does not currently provide this feature.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. Are there any specific warnings or things I should be aware of
 | 
			
		||||
before using OfflineIMAP?
 | 
			
		||||
 | 
			
		||||
A. Yes.  OfflineIMAP does a two-way synchronization.  That is, if you
 | 
			
		||||
make a change to the mail on the server, it will be propogated to your
 | 
			
		||||
local copy, and vise-versa.  Some people might think that it would be
 | 
			
		||||
wise to just delete all their local mail folders periodically.  If you
 | 
			
		||||
do this with OfflineIMAP, remember to also remove your local status
 | 
			
		||||
cache (~/.offlineimap by default).  Otherwise, OfflineIMAP will take
 | 
			
		||||
this as an intentional deletion of many messages and will interpret
 | 
			
		||||
your action as requesting them to be deleted from the server as well.
 | 
			
		||||
(If you don't understand this, don't worry; you probably won't
 | 
			
		||||
encounter this situation)
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. What's thie Mailbox name recorder (mbnames) thing all about?
 | 
			
		||||
 | 
			
		||||
A. The Mutt mail reader is not capable of automatically determining
 | 
			
		||||
the names of your mailboxes.  OfflineIMAP can help it (or many other)
 | 
			
		||||
programs out be writing these names out in a format you specify.  See
 | 
			
		||||
the example offlineimap.conf file for details.
 | 
			
		||||
 | 
			
		||||
--------------------------------------------------
 | 
			
		||||
 | 
			
		||||
Q. Can I synchronize multiple accounts with OfflineIMAP?
 | 
			
		||||
 | 
			
		||||
A. Sure.  Just name them all in the accounts line in the general
 | 
			
		||||
section of the config file, and add a per-account section for each one.
