=======================================================================
|
|
Q. What is the default imapsync behaviour about folders?
|
|
|
|
By default, Imapsync syncs all folders, one by one, in alphanumeric order.
|
|
|
|
The IMAP protocol has a specific way to code folders names,
|
|
especially when these names use non-ascii 7bit characters.
|
|
This encoding is called utf7imap.
|
|
|
|
Imapsync uses the same encoding as IMAP, utf7imap.
|
|
|
|
In order to well specify folders names on the command line, imapsync
|
|
prints the complete folder list of both sides at the beginning of each run.
|
|
|
|
The left column is the encoding you have to use, without the first enclosing
|
|
square brackets [], the right column is the human utf8 view.
|
|
|
|
|

|
|
Q. What are the options to select folders?
|
|
|
|
R. From https://imapsync.lamiral.info/README
|
|
|
|
OPTIONS/folders
|
|
|
|
--folder str : Sync this folder.
|
|
--folder str : and this one, etc.
|
|
--folderrec str : Sync this folder recursively.
|
|
--folderrec str : and this one, etc.
|
|
|
|
--folderfirst str : Sync this folder first. Ex. --folderfirst "INBOX"
|
|
--folderfirst str : then this one, etc.
|
|
--folderlast str : Sync this folder last. --folderlast "[Gmail]/All Mail"
|
|
--folderlast str : then this one, etc.
|
|
|
|
--nomixfolders : Do not merge folders when host1 is case-sensitive
|
|
while host2 is not (like Exchange). Only the first
|
|
similar folder is synced. Example: with folders
|
|
"Sent", "SENT" and "sent" on host1, only "Sent"
|
|
will be synced to host2.
|
|
|
|
--skipemptyfolders : Empty host1 folders are not created on host2.
|
|
|
|
--include reg : Sync folders matching this regular expression
|
|
--include reg : or this one, etc.
|
|
If both --include --exclude options are used, then
|
|
include is done before.
|
|
--exclude reg : Skips folders matching this regular expression
|
|
Several folders to avoid:
|
|
--exclude 'fold1|fold2|f3' skips fold1, fold2 and f3.
|
|
--exclude reg : or this one, etc.
|
|
|
|
|
|
=======================================================================
|
|
Q. Is it ok to use --subfolder1 and --subfolder2 to just select folders?
|
|
|
|
R. No.
|
|
|
|
If you do:
|
|
|
|
imapsync ... --subfolder1 Foo --subfolder2 Foo
|
|
|
|
then it ends up with all messages from Foo going to Foo/INBOX
|
|
|
|
|
|
=======================================================================
|
|
Q. How can I sync only one folder?
|
|
|
|
R. Use --folder option.
|
|
|
|
imapsync ... --folder MyFolder
|
|
|
|
If you have more specific folders to sync just add several --folder
|
|
|
|
imapsync ... --folder MyFolder --folder ThisFolder --folder ThatFolder
|
|
|
|
|
|
=======================================================================
|
|
Q. What are --subscribe and --subscribed for, and how can they be used?
|
|
|
|
R. In the IMAP protocol each user can subscribe to one or more folders.
|
|
Then one can configure his email software to just see his subscribed
|
|
folders. That's an IMAP feature.
|
|
|
|
Imapsync can use this imap feature to select subscribed folders
|
|
and also subscribe to folders on host2. Here are the options:
|
|
|
|
--subscribed : Transfers subscribed folders.
|
|
--subscribe : Subscribe to the folders transferred on the
|
|
host2 that are subscribed on host1. On by default.
|
|
--subscribeall : Subscribe to the folders transferred on the
|
|
host2 even if they are not subscribed on host1.
|
|
|
|
|
|
=======================================================================
|
|
Q. How to exclude a folder hierarchy like "public"?
|
|
|
|
R. Use:
|
|
|
|
--exclude "public"
|
|
|
|
|
|
=======================================================================
|
|
Q. How to exclude only the INBOX folder?
|
|
|
|
R. Use:
|
|
|
|
imapsync ... --exclude "^INBOX$"
|
|
|
|
A good way to see what will be done is to first use:
|
|
|
|
imapsync ... --exclude "^INBOX$" --justfolders --nofoldersizes --dry
|
|
|
|
=======================================================================
|
|
Q. How to exclude folders matching SPAM no matter the case,
|
|
aka, how to be case insensitive?
|
|
|
|
R. Use:
|
|
|
|
imapsync ... --exclude "(?i)spam"
|
|
|
|
A good way to see what will be done is to first use:
|
|
|
|
imapsync ... --exclude "(?i)spam" --justfolders --nofoldersizes --dry
|
|
|
|
|
|
=======================================================================
|
|
Q. How to make option --folder "MyFolder" be recursive?
|
|
|
|
Two solutions:
|
|
|
|
R1. Use
|
|
|
|
--folderrec "MyFolder"
|
|
|
|
R2. Use --include "^MyFolder"
|
|
Then the folder "MyFolder" and all its subfolders will be handled
|
|
and only them.
|

|
Q. How to change folders names or move them elsewhere?
|
|
|
