I keep getting individual emails. I have tried to change the setting so I only get emails daily not every time someone posts. Can you please make this change for me.

charter.net is blocking all Digital Ocean droplet email
by John Stoffel Feb. 13, 2019

Feb. 13, 2019

I need to vent here. Charter.net which provides my internet, sucks. They are now refusing to accept email from *any* IP blocks owned by Digital Ocean, even though I've got a good mail setup on a droplet there, with proper DNS entries, SPF, etc. So I'm looking to spin up a new instance on some other provider, or I'm going to try and route the email via my @charter.net account that I have since I'm a customer. And I have opened a ticket with them. No answer. Jerks. What do people think of Vultr.com? Seems pretty comparable... I just wonder when Charter will block their IP blocks... Jerks. I think it's too expensive to buy an IPv4 address for more permanent use, since it's too easy for that block of 256 to be blanket banned by some jerks. Grr!!!!! John

I’m struggling w/ printers in a small office and i've struggled to get any kind of guidance on-line. The volume of pages printed at the office is probably around 100 pages a day and there are 4 printers — all HPs and all consumer grade — each printer has its purpose, e.g. there's an 11x17 printer, one color laser, one BW laster, one color inkjet. The office is all iMACs, which connect to a Linux CUPS server. The iMacs were networking directly w/ the printers, but i added the CUPS server to try to mitigate the poor reliability with only marginal results. Routinely printers become “paused” in CUPS so i need to go in and ‘unpause’ them, also some printers just fall of the network entirely. Inevitably the only printer that works most of the time is the ink-jet which is a lot more expensive to re-fill. I’m looking for a reliable solution. If anyone has a recomendation that’d be great!
