 +=== Debugging ===
 +
 +You can log the dialogue with the mail server by including ''/debug'' within the value of ''$bounce_mailbox_port'', e.g. 
 +
 +<code php>$bounce_mailbox_port = '993/imap/ssl/debug';</code>
 +
 +and by setting a variable in config.php
 +
 +<code php>$log_options = [
 +    'threshold' => 'DEBUG',
 +];</code>
 +
 +Now the plugin will write the dialogue to a file in the phplist temporary directory, identfied by the ''$tmpdir'' variable in config.php. The file will be named for the current day, ''log_yyyy-mm-dd.txt''. 
 +
 +Alternatively you can specify a particular directory for the log file. The directory must be writeable by the web server process. 
 +<code php>$log_options = [
 +    'threshold' => 'DEBUG',
 +    'dir' => '/path/to/directory',
 +];</code>
  
 +The dialogue will be logged similar to this
