sieve-filter editheader

3 Apr 2025


      Hi,
I'm trying to use the editheader extension of sieve, without success.
If you can help, I would appreciate it.
My setup looks like this:
cat 90-sieve.conf
plugin {
sieve = file:~/sieve;active=~/.dovecot.sieve
sieve_plugins = sieve_extprograms
sieve_extensions = +body +editheader
# with this line it doesn't work either:
# sieve_global_extensions = +editheader
}
dovecot restarted
###
# dovecot.sieve
#
###
#
require [  
"fileinto",  
"editheader",
"body",  
"envelope",  
"imap4flags",  
"regex",  
"variables",  
"relational"
];
#
...
sievec dovecot.sieve :
dovecot: line 8: error: require command: unknown Sieve capability
'editheader'.
dovecot: error: validation failed.
sievec(root): Fatal: failed to compile sieve script 'dovecot.sieve'
