New version of POPcon online - v3.77

The new version 3.77 of POPcon/POPcon PRO/POPcon NOTES is now online. This time we only worked throug a long list of little changes:

• New: Automatic removal of emails that are 0 bytes long (usually caused by antispam or antivirus products)
• New: Special support for scanner/fax devices that always email with the same message id (Dell MFP for example) by switching off the Message-ID duplicates filter for those.
• New: Archive to different folders for each account in PRO version
• Improved: Don't spam-check emails more than once in case the transfer to exchange is interrupted and delivery of the same email is attempted again later.
• Improved: Adds additional header field "x-original-from" if the FROM address was invalid and replaced with unknown@unknown.com
• Improved: Don't deliver same email twice if once delivered normally (for TO: address) and second delivery would be due to CC or BCC address in same email causing a reroute due to unknown address or POPcon PRO rules
• New: Support for "554 Too many Received: headers" SMTP error message now causes email to go to BADMAIL folder
• New: Filtering of "env-from" part of received..for headers. That part is not taken as TO: address
• New: Special support for emails from voicemail systems: Filename voicemal.wav and voice.wav of attachments are modified to stop Outlook from wrapping around at voicemail.wav(99) back to voicemail.wav(1). Users needed to manually clear Outlook caches because of this Outlook bug.
• Bugfix: Stop repeated mail cycles at complex schedule times
