Editheader Extension
Relevant specifications
=======================
RFC5293 - doc/rfc/editheader.rfc5293.txt
Description
===========
The editheader extension [RFC5293] enables sieve scripts to interact with other
components that consume or produce header fields by allowing the script to
delete and add header fields.
Configuration
=============
The editheader is not available by default and needs to be enabled explicitly by
adding it to the sieve_extensions setting.
The following settings can be configured for the editheader extension (default
values are indicated):
sieve_editheader_max_header_size = 2048
The maximum size in bytes of a header field value passed to the addheader
command. The minimum value for this setting is 1024 bytes. The value is in
bytes, unless followed by a k(ilo).
sieve_editheader_protected =
A space-separated list of headers that cannot be added to nor removed from the
message header. The `Received:' and `Auto-Submitted:' fields are always
protected and the `Subject:' header cannot be protected, as required by the
RFC specification; adding one of these headers to this setting has no effect.
Invalid values for the settings above will make the Sieve interpreter log
a warning and revert to the default values.
Example
=======
plugin {
# Use editheader
sieve_extensions = +editheader
# Header fiels must not exceed one 1k
sieve_editheader_max_header_size = 1k
# Protect special header
sieve_editheader_protected = X-Verified
}
