.SH "NAME"
Sympa::Spindle::TransformIncoming \-
Process to transform messages \- first stage
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class executes the first stage of message transformation to be sent
through the list. This stage is put before storing messages into archive
spool (See also Sympa::Spindle::DistributeMessage).
Transformation processes by this class are done in the following order:
.IP "\(bu" 4
Executes \f(CW\*(C`pre_distribute\*(C'\fR hook of message hooks
if available.
.IP "\(bu" 4
Adds \f(CW\*(C`X\-Sympa\-Topic\*(C'\fR header field, if any message topics
(see Sympa::Spool::Topic) are tagged for the message.
.IP "\(bu" 4
Anonymizes message,
if \f(CW\*(C`anonymous_sender\*(C'\fR list configuration
parameter is enabled.
.IP "\(bu" 4
Adds custom subject tag to \f(CW\*(C`Subject\*(C'\fR field, if
\&\f(CW\*(C`custom_subject\*(C'\fR list configuration
parameter is available.
.IP "\(bu" 4
Enables message tracking (see Sympa::Tracking) if necessary.
.IP "\(bu" 4
Removes header fields specified by
\&\f(CW\*(C`remove_headers\*(C'\fR.
.PP
Then this class passes the message to the next stage of transformation.
.SH "CAVEAT"
.IX Header "CAVEAT"
.IP "\(bu" 4
Transformation by this class can break integrity of \s-1DKIM\s0 signature,
because some header fields including \f(CW\*(C`From\*(C'\fR, \f(CW\*(C`Message\-ID\*(C'\fR and \f(CW\*(C`Subject\*(C'\fR may
be altered.
