1.Running Thunderbird 115.6.0 64 bit on Windows 10. 2.Using Microsoft Defender as AntiVirus and I set Thunderbird profile folder to be excluded from AV. 3.Getting emails from a single Earthlink pop server account. Problem: When clicking Get Messages it works great except yesterday there was one single email on the pop server that would not download properly. It prevented all subsequent messages from downloading. It is a valid email and is not spam. When I searched for the message, it showed multiple times (about 50) in the Thunderbird Inbox. When I deleted the email from the pop server, everything works again. What is there about this messages that causes it to lockup the get message process? Thanks for your help, John Here is the problem email header: Authentication-Results:mail142c38.carrierzone.com; spf=pass smtp.mailfrom=bankhometown.com Content-Transfer-Encoding:8bit Content-Type:text/plain; charset=us-ascii Date:16 Feb 2024 23:37:56 -0500 Dmarc-Filter:OpenDMARC Filter v1.4.1 mail142c38.carrierzone.com 41H4bxPb013175 From:PPDONOTREPLY@bankhometown.com Message-ID:<3w65bxfyau-1@ppt-gw2.cocci.com> Mime-Version:1.0 Received:from ext-smtp.cocci.com (mail-ext01.cocci.com [204.60.84.37]) by mail142c38.carrierzone.com (8.14.9/8.13.1) with ESMTP id 41H4bxPb013175 for <lisa@bcscompany.com>; Fri, 16 Feb 2024 23:38:02 -0500 Received-Spf:pass (mail142c38.carrierzone.com: domain of ppdonotreply@bankhometown.com designates 204.60.84.37 as permitted sender) receiver=mail142c38.carrierzone.com; client-ip=204.60.84.37; helo=ext-smtp.cocci.com; envelope-from=ppdonotreply@bankhometown.com; x-software=spfmilter 2.001 http://www.acme.com/software/spfmilter/ with libspf2-1.2.10; Return-Path:<ppdonotreply@bankhometown.com> Subject:Positive Pay System Notifications To:lisa@bcscompany.com X-Cocc-Mailscanner:Not scanned: please contact your Internet E-Mail Service Provider for details X-Cocc-Mailscanner-Information:Please contact the ISP for more information X-Cocc-Msgid:DB8A556B4.A1271 X-Da-Pass:W0T0 X-Envelope-From:ppdonotreply@bankhometown.com X-Mime-Autoconverted:from quoted-printable to 8bit by mail142c38.carrierzone.com id 41H4bxPb013175 X-Origin-Country:US X-Spam-Flag:NO X-Vade-Spamcause:gggruggvucftvghtrhhoucdtuddrgedvledrvdefgdejvdcutefuodetggdotefrodftvfcurfhrohhfihhlvgemucfjqffuvffqrffktedpgffpggdqveefkeenuceurghilhhouhhtmecufedtudenucenucfjughrpegghffvfffutgfgkfesthhqredttddtvdenucfhrhhomheprffrfffqpffqvfftgffrnfgjsegsrghnkhhhohhmvghtohifnhdrtghomhenucggtffrrghtthgvrhhnpeekjeehieetvefftedvheekhedvudetffeufeehveejjeetvdfhteegffevleduudenucfkphepvddtgedriedtrdekgedrfeejnecuvehluhhsthgvrhfuihiivgeptdenucfrrghrrghmpehinhgvthepvddtgedriedtrdekgedrfeejpdhhvghlohepvgigthdqshhmthhprdgtohgttghirdgtohhmpdhmrghilhhfrhhomhepphhpughonhhothhrvghplhihsegsrghnkhhhohhmvghtohifnhdrtghomhdpnhgspghrtghpthhtohepuddprhgtphhtthhopehlihhsrgessggtshgtohhmphgrnhihrdgtohhm X-Vade-Spamscore:0 X-Vade-Spamstate:clean X-Whl:LR
