 * Hi, I would like to try this plugin out but am getting several errors on activation:
 * `The plugin generated 6167 characters of unexpected output during activation.
   If you notice “headers already sent” messages, problems with syndication feeds
   or other issues, try deactivating or removing this plugin.`
 * I have not poked around to see what those are, it’s been awhile since I’ve had
   to chase those down. More critically, after configuring my mailbox, I get a white
   screen of death with these errors when I click save on the options page:
 * `Deprecated: whitelist_options is deprecated since version 5.5.0! Use apply_filters_deprecated
   instead. Please consider writing more inclusive code.`
 * `Deprecated: add_option_whitelist is deprecated since version 5.5.0! Use add_allowed_options()
   instead.`
 * The debug stack for the first (I think) was triggered by the second, which in
   turn was triggered by line 255 in `postie.php`
