Gmail problem sending from your own SMTP server
by Hartmut W Sager 21 Apr '20

21 Apr '20

Gmail is sure piling up its problems like never before in my 8-10 years of using it. In addition to the other issues of the last two months, we now have: The recent intermittent Gmail problem in sending from your own SMTP server (if you don't want your "send from" address at your own domain name to be an "alias" of your Gmail address) has now become an "always happens" problem. Here's the failure message you get from Gmail: Message not delivered You're sending this from a different address or alias using the 'Send mail as' feature. The settings for your 'Send mail as' account are misconfigured or out of date. Check those settings and try resending. TLS Negotiation failed, the certificate doesn't match the host. After much experimenting and Internet research, I found the answer buried in Gmail support forums - an answer from a smart user, not from Google. In my case, since I use Tucows/OpenSRS for my SMTP server, the chain is smtp-1.marityme.com [cname] --> smtp.marityme.com.cust.a.hostedemail.com --> 216.40.42.5 --> [RDNS] mail.hostedemail.com Tucows/OpenSRS specifies the server *smtp.marityme.com.cust.a.hostedemail.com <http://smtp.marityme.com.cust.a.hostedemail.com>*, which I cname to for concenience and elegance, and that resolves to * 216.40.42.5*, whose RDNS lookup gives *mail.hostedemail.com <http://mail.hostedemail.com>*. Now, unlike before, Gmail expects me to give *mail.hostedemail.com <http://mail.hostedemail.com>* as the SMTP server in the "send from" configuration, and then the sending mechanism works again (at least yesterday and today, who knows about tomorrow). The purpose of this post is to save other members days of headache trying to figure this one out. Hartmut W Sager - Tel +1-204-339-8331

DIMMs and SODIMMs free to a good home v3.0
by Adam Thompson 19 Apr '20

19 Apr '20

v1 - SODIMMs only v2 - updated SODIMM list, added DIMMs v3 - removed Samsung 8GB DIMMs, expanded distribution of email Sorted by type, then speed, then size. I'd like to not move these from my old basement to my new basement this summer... and no, I have no idea why I still have PC100 and PC133 RAM hanging around - the DIMM in the top row is clearly from Computer Boulevard! Strong preference to people who actually have a use for it, not just moving it from my shelf to yours. I'll probably drop these off at a recycler sometime next week if no-one speaks up for them. Feel free to forward this to other people/places. -Adam QTY FORM FACTOR VCC BRAND PART# SIZE SPEED CL ECC? Additional Markings 1 168-pin DIMM 3V ? (Micron) ? 32MB PC100 CL2 No - 1 168-pin DIMM 3V ?

DNS linters / consistency checkers?
by Adam Thompson 06 Apr '20

06 Apr '20

Between roughly 10 and 20 years ago there was a bevy, nearly a plethora, of tools to scan your various BIND zone files and check that everything was in order, no illegal names existed, PTRs matched up with As, etc., etc. Today I can only find two, one is dead (dlint) and doesn't check zone files only live DNS, and the other (validns) doesn't do PTR<-->A checks which is what I really wanted. Where did all the other zone consistency-checking tools go? Anyone have any pointers / links? Thanks, -Adam

Gmail spam filtering super-aggressive lately
by Hartmut W Sager 03 Apr '20

03 Apr '20

I've had a lot of trouble in the last few months with Gmail's spam filtering having become super-aggressive, but tonight we have a live case worthy of analysis. In the thread "Opinions on Fedora Server" initiated by Alberto Abrao <alberto(a)abrao.net>, *both* of Alberto's postings went to my Gmail spam, while Trevor Cordes's posting came through fine. A detail on my use of Gmail: I use it as infrastructure for my own e-mail addresses @marityme.net. Incoming e-mails to @marityme.net are forwarded into my Gmail address from somewhere else, and outgoing e-mails from @ marityme.net are sent from Gmail where I set up these addresses as valid "from" addresses. Yeah, I suspect the trouble is somewhere in Gmail's new expectations re TXT SPF, DKIM, DomainKeys, and such. Hartmut W Sager - Tel +1-204-339-8331

Main firewall / router for public facing subnet
by Alberto Abrao 02 Apr '20

02 Apr '20

Hi folks, hope everybody is safe and sound. This may be a basic question for most of you, but at any rate, I would rather ask here as I like the way MUUG members approach things. I have a Shaw connection with a few Static IPs. As of now the modem is bridged, and each machine grabs its own IP and goes to town, be it a static for servers or a dynamic for my local network router. On each of these, I set up firewall and whatever else is needed. I have the feeling that's redundant. That, and having a main router in front of them would help me set up things such as QoS and a central firewall. I am used to doing this for simple NAT duties, but this time I would have a router managing public facing IP addresses. Any tips on what should I look for to get started? Thanks! -- Alberto Abrao 204-202-1778 204-558-6886 www.abrao.net

win server licence
by Dan Keizer 30 Mar '20

30 Mar '20

well, first off this is not for me (honest!) .. a guy I know is looking to run a windows server licence for some specific software vertical he is looking at ... (i asked - they dont have a linux port) the company (no idea who it is) claims the software works best on server licence as it utilizes the hardware better ... he's looking at trying to save money on the licence, so does anyone have 2016 or 2008 server licences on dead machines that can be repurposed? wondering if the likes of MER may as well.... thanks. Dan.
