gmail bouncing emails from my domain.
by Nev Young 06 Mar '23

06 Mar '23

I suspect this is a naive question but I'm at a loss how to fix this. I send emails using thunderbird and msmtp. I post via my ISP's smtp server (smpt.zen.co.uk) This has allowed me to send emails to any one as any one. e.g. this has come from alug(a)nevilley.org.uk very recently emails sent to gmail users have started to bounce undelivered with the likes of: (email address redacted) This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: ##############(a)gmail.com host gmail-smtp-in.l.google.com [108.177.15.27] SMTP error from remote mail server after pipelined end of data: 550-5.7.26 This message does not pass authentication checks (SPF and DKIM both 550-5.7.26 do not pass). SPF check for [nevilley.org.uk] does not pass with ip: 550-5.7.26 [212.23.1.22].To best protect our users from spam, the message has 550-5.7.26 been blocked. Please visit 550-5.7.26https://support.google.com/mail/answer/81126#authentication for more 550 5.7.26 information. p9-20020adfe609000000b002ca647fe919si1349235wrm.527 - gsmtp Do I need to do something with thunderbird on my PC or is this a problem for Zen? Any help gratefully received. Nev

HP Microservers or similar
by Mark Rogers 20 Feb '23

20 Feb '23

Over the years I've used a handful of HP Micro servers to run a Linux-based web server application. To be honest I suspect it would comfortably run on a Pi, to give you some idea of power requirements. However it does need to be dependable and one of the criteria is RAID (software RAID 1 is fine). We replace the hardware every few years so the question I have is: what is a good small server for Linux these days? Apart from the requirement to host 2 SATA drives there isn't much in terms of hardware requirements. We don't even use a lot of disk space - maybe a few dozen GB. One HDD gets replaced annually so that no disk is older than 2y, using commodity disks in the 1-2TB range but partitioned to only use 200GB on each disk, just because we don't need more and it makes the swap to a new disk quicker. Hot swap not needed. Would consider SSD for the new server. I was about to get a quote for an HP Gen10 MicroServer when it crossed my mind that maybe just buying the same server out of habit wasn't necessarily the right approach! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

SPF Record problem
by steve-ALUG＠hst.me.uk 17 Feb '23

17 Feb '23

Hi all I have just seen a message saying that Gmail is going to reject all emails without an SPF set up, so I thought I'd try for my mail server. Of course I have immediately run into trouble. My email gets sent via a virgin media server, currently smtp.ntlworld.com but I may update to smtp.virginmedia.com in future I used an SPF Wizard https://www.spfwizard.net It generated v=spf1 mx a a:smtp.ntlworld.com a:smtp.virginmedia.com ~all which if I read it right, accepts my domain, or smtp.ntlworld.com or smtp.virginmedia.com as valid email handlers for my email, with a "soft fail". [I used a soft fail for debugging - I want to swap to hard fail, but can't until I get this right] I've sent a couple of emails to test, and here's the snag. By the time they get to google, they're coming from 212.54.57.96 212.54.57.97 If I do a whois on that, I get back ziggo.nl (VODAFONEZIGGO) I expect email to smtp.ntlworld.com gets redirected to another server, or group of servers, inside virgin media, no doubt with a name like MAILSERVER.virginmedia.com (for some value of MAILSERVER), and that's handled by a range of IP addresses. How can I craft a valid SPF record, if I don't know which IP addresses or name to put in the spf? Why is virgin media mail ending up on a server in NL, or is that just an out-of-date or wrong whois lookup? Any ideas????? I'm struggling! Steve

Looking for E-Mail hosting as opposed to web hosting, recommendations wanted
by Chris Green 24 Nov '22

24 Nov '22

I am having trouble with my E-Mail at the moment. Since the move from 'Cloud' hosting to their cPanel services my E-Mail at TsoHost hasn't run very well. So I'm wondering if I might move my two, basically E-Mail only, domains away from TsoHost. There's basically four users with lots of forwarding and other such things. I need to host two domains, have the ability to create IMAP/POP3 mailboxes, multiple forwarding, etc. So it's not *big* but does need to be flexible (and cheap!). Does anyone have any recommendations? -- Chris Green

A remaining puzzle with AMD
by Peter 18 Nov '22

18 Nov '22

This is about my new AMD installation. After finally figuring out how to upgrade just the kernel so as to be able to make pm-suspend work properly, there is one remaining issue I can't seem to figure out, and that is the temperature sensors. I have lm-sensors installed and this is what it shows: k10temp-pci-00c3 Adapter: PCI adapter Tctl: +31.5°C amdgpu-pci-0b00 Adapter: PCI adapter vddgfx: 856.00 mV vddnb: 737.00 mV edge: +30.0°C PPT: 0.00 W nct6792-isa-0290 Adapter: ISA adapter in0: 864.00 mV (min = +0.00 V, max = +1.74 V) in1: 0.00 V (min = +0.00 V, max = +0.00 V) in2: 3.34 V (min = +0.00 V, max = +0.00 V) ALARM in3: 3.34 V (min = +0.00 V, max = +0.00 V) ALARM in4: 0.00 V (min = +0.00 V, max = +0.00 V) in5: 0.00 V (min = +0.00 V, max = +0.00 V) in6: 808.00 mV (min = +0.00 V, max = +0.00 V) ALARM in7: 3.41 V (min = +0.00 V, max = +0.00 V) ALARM in8: 3.25 V (min = +0.00 V, max = +0.00 V) ALARM in9: 1.83 V (min = +0.00 V, max = +0.00 V) ALARM in10: 176.00 mV (min = +0.00 V, max = +0.00 V) ALARM in11: 128.00 mV (min = +0.00 V, max = +0.00 V) ALARM in12: 1.84 V (min = +0.00 V, max = +0.00 V) ALARM in13: 1.68 V (min = +0.00 V, max = +0.00 V) ALARM in14: 0.00 V (min = +0.00 V, max = +0.00 V) fan1: 384 RPM (min = 0 RPM) fan2: 1023 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) fan4: 0 RPM (min = 0 RPM) fan5: 0 RPM (min = 0 RPM) SYSTIN: +119.0°C (high = +0.0°C, hyst = +0.0°C) sensor = thermistor CPUTIN: +30.5°C (high = +80.0°C, hyst = +75.0°C) sensor = thermistor AUXTIN0: +37.0°C (high = +0.0°C, hyst = +0.0°C) ALARM sensor = thermistor AUXTIN1: +108.0°C sensor = thermistor AUXTIN2: +109.0°C sensor = thermistor AUXTIN3: -128.0°C sensor = thermistor SMBUSMASTER 0: +31.5°C PCH_CHIP_CPU_MAX_TEMP: +0.0°C PCH_CHIP_TEMP: +0.0°C PCH_CPU_TEMP: +0.0°C TSI0_TEMP: +31.5°C intrusion0: OK [small snip...] I don't get it. First, its impossible there can be 100C+ temps. The case fan is silent, the psu fan is not moving, the system works fine and feels cool in fact cold to the touch. Second, how can it possibly be -128.0C on one of the readings? The system itself seems to be running quite fast and perfectly silently. I have a Noctua low profile CPU cooler which should be more than equal to the cpu installed, the psu is a Corsair SFF, Gold 450, and it all seems fine. You hear the fans for a few seconds at startup, after that, silence. I am running Debian stable but as in the earlier post when trying to get suspend to work, have the testing kernel installed. Was hoping that would clear up the temp problem but no luck. By the way, acpi -t returns nothing. Any suggestions? Or should I just stop worrying? Peter

Re: A remaining puzzle with AMD
by Peter 18 Nov '22

18 Nov '22

The only thing I could think of, as an alternate source of temp information, was to restart the system after it had been on for a few hours and go immediately into bios and look at the temps provided in the HW Monitor tab. Well, fans were reported as doing roughly the same speeds as reported by lm-sensors, and the cpu temperature is reported as 43C. So I guess its a matter of not worrying about it, and maybe in some update at some point it will get fixed. Thanks. Its good to know that others get similarly erratic results from lm-sensors, so its not just me doing something stupid! Peter
