.SH NAME
isync - synchronize IMAP4 and maildir mailboxes
..
.SH SYNOPSIS
.B isync
[
.I options...
]
.I file
..
.SH DESCRIPTION
.B isync
is a command line application which synchronizes a local maildir-style
mailbox with a remote IMAP4 mailbox, suitable for use in IMAP-disconnected
mode.  Multiple copies of the remote IMAP4 mailbox can be maintained, and
all flags are synchronized.
..
.SH OPTIONS
.TP
\fB-c\fR, \fB--config\fR \fIfile\fR
Read configuration from
.I file
By default, configuration is read from ~/.isyncrc if it exists.
.TP
.B -d, --delete
Causes
.B isync
to delete messages from the local maildir mailbox which do not exist on the
IMAP server.  By default,
.I dead
messages are
.B not
deleted.
.TP
.B -e, --expunge
Causes
.B isync
to permanently remove all messages marked for deletion in both the local
maildir mailbox and the remote IMAP mailbox.  By default, messages are
.B not
expunged.
.TP
.B -f, --fast
Causes
.B isync
to skip the step of synchronzing message flags between the local maildir
mailbox and the IMAP mailbox.  Only new messages existing on the server will
be fetched into the local mailbox.
.TP
.B -h, --help
Displays a summary of command line options
.TP
\fB-p\fR, \fB--port\fR \fIport\fR
Specifies the port on the IMAP server to connect to (default: 143)
.TP
\fB-r\fR, \fB--remote\fR \fIbox\fR
Specifies the name of the remote IMAP mailbox to synchronize with
(Default: INBOX)
.TP
\fB-s\fR, \fB--host\fR \fB[\fRimaps:\fB]\fR\fIhost\fR
.P
Specifies the hostname of the IMAP server
.TP
\fB-u\fR, \fB--user\fR \fIuser\fR
Specifies the login name to access the IMAP server (default: $USER)
.TP
.B -v, --version
Displays
.B isync
version information
.TP
.B -V, --verbose
Enables
.I verbose
mode, which displays the IMAP4 network traffic.
..
.SH CONFIGURATION
.B isync
reads
.I ~/.isyncrc
to load default configuration data.  Each line of the configuration file
consists of a command.  The following commands are understood:
.TP
\fBMailbox\fR \fIpath\fR
Defines a local maildir mailbox.  All configuration commands following this
line, up until the next
.I Mailbox
command, apply to this mailbox only.
..
.TP
\fBHost\fR \fB[\fRimaps:\fB]\fR\fIname\fR
Defines the DNS name or IP address of the IMAP server.  If the hostname is
prefixed with
.I imaps:
the connection is assumed to be a SSL connection to port 993 (though you can
change this by placing a
.B Port
command
.B after
the
.B Host
command.  Note that some servers support SSL on the default port 143.
.B isync
will always attempt to use SSL if available.
..
.TP
\fBPort\fR \fIport\fR
Defines the TCP port number on the IMAP server to use (Default: 143)
..
.TP
\fBBox\fR \fImailbox\fR
Defines the name of the remote IMAP mailbox associated with the local
maildir mailbox (Default: INBOX)
..
.TP
\fBUser\fR \fIusername\fR
Defines the login name on the IMAP server (Default: current user)
..
.TP
\fBPass\fR \fIpassword\fR
Defines the password for
.I username
on the IMAP server.  Note that this option is
.B NOT
required.  If no password is specified in the configuration file,
.B isync
will prompt you for it.
..
.TP
\fBAlias\fR \fIstring\fR
Defines an alias for the mailbox which can be used as a shortcut on the
command line.
..
.TP
\fBMaxSize\fR \fIbytes\fR
Sets a threshold for the maximum message size (in bytes) for which
.B isync
should fetch from the server.  This is useful for weeding out messages with
large attachments.  If
.I bytes
is 0, the maximum file size is
.B unlimited.
..
.TP
\fBUseNamespace\fR \fIyes|no\fR
Selects whether
.B isync
should select mailboxes using the namespace given by the NAMESPACE command.
This is useful with broken IMAP servers. (Default:
.I yes
)
..
.TP
\fBRequireSSL\fR \fIyes|no\fR
.B isync
will abort the connection if a TLS/SSL session to the IMAP
server can not be established.  (Default:
.I yes
)
..
.TP
\fBCertificateFile\fR \fIpath\fR
File containing X.509 CA certificates used to verify server identities.
..
.TP
\fBUseSSLv2\fR \fIyes|no\fR
Should
.B isync
use SSLv2 for communication with the IMAP server over SSL?  (Default:
.I yes
)
..
.TP
\fBUseSSLv3\fR \fIyes|no\fR
Should
.B isync
use SSLv3 for communication with the IMAP server over SSL?  (Default:
.I yes
)
..
.TP
\fBUseTLSv1\fR \fIyes|no\fR
Should
.B isync
use TLSv1 for communication with the IMAP server over SSL?  (Default:
.I yes
)
..
.P
Configuration commands that appear prior to the first
.B Mailbox
command are considered to be
.I global
options which are used as defaults when those specific options are not
specifically set for a defined Mailbox.  For example, if you use the same
login name for several IMAP servers, you can put a
.B User
command before the first
.B Mailbox
command, and then leave out the
.B User
command in the sections for each mailbox.
.B isync
will then use the global value by default.
..
.SH FILES
.TP
.B ~/.isyncrc
Default configuration file
..
.SH BUGS
maildir(5) states that readers should not attempt to parse the filename of a
a message other than the :info field.  However, since
.B isync
relies on using the message UIDs that info must be inserted into the
filename in a way which will be interoperable with existing readers.  So
the UID is placed in the filename of the messages in the local maildir
mailbox rather than the :info field.
