What's New:

  • Create new account auto-configuration: POP Peeper now uses an online database to import server settings based on your email address (with capability to customize for your personal domain)
  • Database and memory optimization. Depending on the number and size of messages, POP Peeper will now: use significantly less memory start significantly faster (less I/O and cpu usage)
  • SSL certificate verification; uses Windows SSL certificates for verification to prevent man-in-the-middle attacks (thanks: Marc Klenotic)
  • AntiJunk: Change: If using the "ignore/junk" notification sound, the sound will not play if the message is marked for deletion as a result of AntiJunk
  • Fix: New algorithm used to determine if black text or white text should be used on account/background color for tray icon
  • Fix: A new font face is used for the tray icon text which uses anti-aliasing to improve legibility
  • Fix: In certain cases, "http://" would display at the beginning of an email when viewing it
  • Fix: Certain SMTP errors should now display more useful information. In particular, sending a restricted file via gmail would previously display "Error verifying message terminator" with no other relevant information; now it will display the reason as described by gmail
  • Fix: In Classic mode (ie. XP-Theme disabled), the icons in the context menus showing user flags were cut off
  • Fix: GDI leak introduced in v4.3
  • Fix: SMTP: when using OAuth2, SMTP was using the login-id instead of the email address to lookup the OAuth2 credentials, which would fail if they were different (uncommon)
  • Fix: SMTP: Issues would occur if the previously selected "default send account" had been deleted; now: prompt will appear if the account doesn't exist
  • Fix: In certain cases, if OAuth2 failed for token refresh, POP Peeper would not report an error
  • Fix: AntiJunk: "Purge bayesian" was not performing its duties
  • Fix: IMAP: timeouts were calculated incorrectly (ie. not reset when partial data received)
  • Fix: IMAP: if server disconnects unexpectedly, it would often report a "Send" error; now it will report "server disconnected unexpectedly"
  • Fix: IMAP: On certain errors, POP Peeper will immediately log back into the server and re-attempt the command (up to 2 retries)
  • Fix: IMAP: Errors occurring during logout are now ignored
  • Fix: POP3: improved error handling (similar to IMAP) for unexpected disconnects and retrying
  • Fix: SMTP: OAuth2 will only be used if the incoming server is using IMAP (this prevents an imminent failure if the account is changed from IMAP to webmail/POP3)
  • When activating just the Plus Pack (and not Pro), "Pro" would remain selected and indicate that it was not activated; now "Plus Pack" is automatically selected to avoid confusion
  • Using MouseWheel when viewing a message will always scroll the message body, regardless of what has the focus (e.g. it won't try to open an attachment)
  • Error log (copy to clipboard format) now includes the number of consecutive errors; helpful for troubleshooting
  • Logger now includes filters
  • Storage options (none/header/entire) has now been designated an 'advanced option'
  • When using Hotmail/Outlook (webmail) protocol, it will default to use SMTP for sending (WebSend is not supported)
