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 \fB-e\fR, \fB--expunge\fR 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 \fB-f\fR, \fB--fast\fR 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 \fB-h\fR, \fB--help\fR 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-q\fR, \fB--quiet\fR Supress feedback messages. .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 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 \fBCopyDeletedTo\fR \fIstring\fR Specifies the remote IMAP mailbox to copy deleted messages prior to expunging (Default: none). .. .TP \fBExpunge\fR \fIyes|no\fR Specifies whether deleted messages are expunged by default (Default: no). \fBNOTE:\fR The .I -e command line option overrides this setting when set to \fIno\fR. .. .TP \fBMailDir\fR \fIstring\fR Specifies the location for your mailboxes if a relative path is specified in a .I Mailbox command (Default: \fI~\fR). .B NOTE: This directive is only meaningful the in .I global section (see below). .. .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 \fBRequireCRAM\fR \fIyes|no\fR If set to .I yes , .B isync will require that the server accept CRAM-MD5 intead of PLAIN to authenticate the user. .. .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 if the imaps port is used, otherwise .I no ) .. .TP \fBUseSSLv3\fR \fIyes|no\fR Should .B isync use SSLv3 for communication with the IMAP server over SSL? (Default: .I yes if the imaps port is used, otherwise .I no ) .. .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. .P When synchronizing multiple mailboxes on the same IMAP server, it is not possible to select different SSL options for each mailbox. Only the options from the first mailbox are applied since the SSL session is reused. .SH SEE ALSO mutt(1), maildir(5) .P Up to date information on .B isync can be found at http://www.sigpipe.org/isync/. .. .SH AUTHOR Written by Michael R.
