Hello,
I seem to be having some issues trying to setup a pipe to PHP scripts
using Sieve Extprograms. I am trying to allow each individual mailbox
to setup its own PHP pipe rules (in other words, each user should be
able to pipe incoming emails to a user defined PHP script).
I have the following lines in my main Sieve configuration file
(/etc/dovecot/conf.d/90-sieve.conf):
sieve_extensions = +vnd.dovecot.pipe
sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.execute
sieve_plugins = sieve_extprograms
I don't see these settings in your dovecot -n output below.
...
I have configured a Sieve service that looks like this
(/etc/dovecot/conf.d/90-sieve-extprograms.conf):
service php {
# Define the executed script as parameter to the sieve service
executable = /var/run/dovecot/sieve-pipe/php.sh
  # Use some unprivileged user for executing the program
  user = dovenull

  # The unix socket located in the sieve_pipe_socket_dir (as
defined in the
# plugin {} section above)
unix_listener sieve-pipe/php {
# LDA/LMTP must have access
user = vmail
mode = 0600
}
}
Contents of /var/run/dovecot/sieve-pipe/php.sh:
#!/usr/bin/php
Sieve script for one of my mailboxes:
require ["fileinto", "regex", "date", "relational", "vacation"];
require ["mailbox", "imap4flags", "vnd.dovecot.pipe"];
# Move spam to spam folder
if header :contains "X-Spam-Flag" "YES" {
fileinto "Junk";
# Stop here so that we do not reply on spams
stop;
}
pipe :try "php /var/www/web2/piping.php support@example.com"
keep;
This results however in the following error in my log file:
main script: line 5: error: require command: unknown Sieve
capability `vnd.dovecot.pipe'.
main script: line 14: error: unknown command 'pipe' (only reported
once at first occurence).
main script: error: validation failed.
I am also not quite confident I have set this up correctly. Am I
heading in the right direction for what I am trying to achieve?
