Small script that can trigger customizable, automatic email repsonses from within Dovecot/sieve scripts.
Configure Dovecot to allow execution of script through the extprogram plugin.
Include into /etc/dovecot/conf.d/90-sieve.conf:
sieve_plugins = sieve_extprograms
sieve_extensions = +vnd.dovecot.execute
And in /etc/dovecot/conf.d/90-sieve-extprograms.conf:
sieve_execute_bin_dir = /usr/lib/dovecot/sieve-execute
Then, copy autoresponder.py into the specified directory
(/usr/lib/dovecot/sieve-execute in this case), make it owned by root:root and
give it 0755 permissions.
Now in your user's sieve script, you need to require the execution plugin:
require ["fileinto","imap4flags","vnd.dovecot.execute"];
Then, you can simply specify rules:
if header :contains "to" ["[email protected]","[email protected]"]
{
addflag "\\Seen";
fileinto "Some Spam";
execute :input "spamresponder" "autoresponder.py";
stop;
}
The identifier given (in this case spamresponder) refers to the identifier
given to the autoresponder script on the command line. You can try it out by
running (as your local user):
$ echo spamresponder | [email protected] /usr/lib/dovecot/sieve-execute/autoresponder.py
This will trigger the "spamresponder" action, as specified by the database
entry in ~/.mail/autoresponder.sqlite3 (the database is created on first
running the script). There is a "test" action defined that you can try out to
get a feeling for it.
