Authentication via remote IMAP server

Available driver settings:

  • host=<template> : IP address or hostname. Allows %variables (e.g. host=imap.%d)
  • port=<port>
  • username=<template> : The default is %u, but this could be changed to for example
  • ssl=imaps / ssl=starttls
  • ssl_ca_dir=<path>

New in version v2.2.30.

  • ssl_ca_file=<path>
  • allow_invalid_cert=yes|no : Whether to allow authentication even if the certificate isn’t trusted. For v2.2 it defaults to “yes”. (v2.2.30+)
  • rawlog_dir=<path>

See also HowTo/ImapcProxy for how to combine this with imapc storage.
