Hi, I've got a customer running their own mail server who is experiencing huge delays on *receiving* emails from btinternet.com senders.
This is ongoing, and appears to be affecting all email to them from all senders with a btinternet.com address. My customer is not noticing any attempts by BT to deliver the emails until the eventual successful delivery. Mail from other senders is working fine and there have been no local changes to their email configuration. Their mail server is at 85.119.83.252 (and 2001:ba8:1f1:f073::2, but none of the eventual deliveries happen over IPv6). They've reported it to [email protected] but aren't getting anywhere as they aren't a customer. None of their correspondents are technically minded so would have difficulty reporting it on their behalf. Has anyone seen anything like this before with btinternet.com? [ I'm just trying to help investigate this on behalf of my customer; I don't have any direct access to their server so am relying on information they've relayed to me. If there's any required information I've missed please let me know and I will relay the request. ] Headers from an example delayed email are below. As you can see it appears to have been held inside btinternet.com / synchronoss.net for about 13 days. Thanks, Andy Envelope-to: [email protected] Delivery-date: Sat, 17 Oct 2020 23:45:09 +0100 Received: from mailomta19-sa.btinternet.com ([213.120.69.25] helo=sa-prd-fep-046.btinternet.com) by cumulus.sinodun.org.uk with esmtps (TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256) (Exim 4.89) (envelope-from <[email protected]>) id 1kTuwh-0000IN-W3 for [email protected]; Sat, 17 Oct 2020 23:45:09 +0100 Received: from sa-prd-rgout-004.btmx-prd.synchronoss.net ([10.2.38.7]) by sa-prd-fep-044.btinternet.com with ESMTP id <20201004112406.noum3440.sa-prd-fep-044.btinternet....@sa-prd-rgout-004.btmx-prd.synchronoss.net> for <[email protected]>; Sun, 4 Oct 2020 12:24:06 +0100 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=btinternet.com; s=btmx201904; t=1601810646; bh=1vDOorT3Rx421J05dLZQyx3o5a5PSPJe4Uova3quROw=; h=Date:Subject:Message-ID:From:To:MIME-Version; b=nPqs/OedVuEBEbuzgyNKrmq3nbFEBng9W+2SHJNbi8IebcMzXrng/bprpUt+addyij80px6qnW5BZ//ztLYYyjZVBkbMbofAKcJOatShFOBdkKmf8OV6maPpg7x1CGwjsBm9858q7k9GUp+sdNRPtnktcX3N9ESRy6mL9BXYL1DPw6XLG51W//EoulOalYHb1UowXz4qb14+NGMNObYzya7w/OfvNJmCCOw5dG4jcqk0i9FR3wjvqbGHHPRR10PF5+nfOA+AhI/I/2oZgll09G1yKc6IW9hORiMnJyspikYpwDGCMP8xKKCcCxgKjZWomzOLgyvAe6mC/Kh6B3jPhg== Authentication-Results: btinternet.com; auth=pass (PLAIN) [email protected] X-Originating-IP: [51.198.106.191] X-OWM-Source-IP: 51.198.106.191 (GB) X-OWM-Env-Sender: [email protected] X-VadeSecure-score: verdict=clean score=0/300, class=clean X-RazorGate-Vade: gggruggvucftvghtrhhoucdtuddrgedujedrgedtgdegudcutefuodetggdotefrodftvfcurfhrohhfihhlvgemuceutffkvffkuffjvffgnffgvefqofdpqfgfvfenuceurghilhhouhhtmecufedtudenucesvcftvggtihhpihgvnhhtshculddquddttddmnecujfgurhepfffukffhvfggtgesrgdtreertddtjeenucfhrhhomhepjfcuggcuofhurhhphhihuceohhgvrghthhgvrhhmuhhrphhhhidvfedutdessghtihhnthgvrhhnvghtrdgtohhmqeenucggtffrrghtthgvrhhnpeevveduleeivdejhfdvvefgfefgueelhffhjefgteetiedvgfeftdekfefgvddthfenucffohhmrghinhepfhgrtggvsghoohhkrdgtohhmpdgtlhhiqhgtrghtvghrihhnghdrtghordhukhdpvghmmhgrshgvfigvshhfuhhlrggtrhgvshdrtghomhdpmhgrrhhkfihoohgurghrthhishhtrdgtohdruhhkpdgtlhgrrhgvshgtrghnughlvghsrdgtohhmnecukfhppeehuddrudelkedruddtiedrudeludenucevlhhushhtvghrufhiiigvpedtnecurfgrrhgrmhephhgvlhhopegludelvddrudeikedrtddrgegnpdhinhgvthephedurdduleekrddutdeirdduledupdhmrghilhhfrhhomhepoehhvggrthhhvghrmhhurhhphhihvdefuddtsegsthhinhhtvghrnhgvthdrtghomheqpdhrtghpthhtohepoehkrghtvgesshhinhhoughunhdrohhrghdruhhkqe X-RazorGate-Vade-Verdict: clean 0 X-RazorGate-Vade-Classification: clean X-SNCR-hdrdom: btinternet.com Received: from [192.168.0.4] (51.198.106.191) by sa-prd-rgout-004.btmx-prd.synchronoss.net (5.8.340) (authenticated as [email protected]) id 5ED9B66114297CBC for [email protected]; Sun, 4 Oct 2020 12:24:06 +0100 Date: Sun, 04 Oct 2020 12:23:51 +0100 Message-ID: <[email protected]> From: Sender <[email protected]> To: Recipient <[email protected]> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="--_com.android.email_414387516046343" X-SA-Exim-Connect-IP: 213.120.69.25 X-SA-Exim-Mail-From: [email protected] X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on cumulus.sinodun.org.uk X-Spam-Level: X-Spam-Status: No, score=-2.1 required=5.0 tests=BAYES_00,DKIMWL_WL_MED, DKIM_SIGNED,DKIM_VALID,DKIM_VALID_AU,DKIM_VALID_EF,HTML_MESSAGE, RCVD_IN_DNSWL_NONE,RCVD_IN_MSPIKE_H3,RCVD_IN_MSPIKE_WL,SPF_HELO_PASS, SPF_PASS autolearn=ham autolearn_force=no version=3.4.2 Subject: =?US-ASCII?Q?Re:_[WLPM_Newsletter]_Wallingford_Lo?= =?US-ASCII?Q?cal_Producers'_Market_3_October=0D=0A_2020?= X-SA-Exim-Version: 4.2.1 (built Tue, 02 Aug 2016 21:08:31 +0000) X-SA-Exim-Scanned: Yes (on cumulus.sinodun.org.uk) _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
