Alibaba Cloud Server > Email SMTP server configuration help needed.

When i change my notification email in the script, my server smtp starts sending old same notification email again and again into new email, i dont know how to ask this question but dont know how to solve.

Hello, from some days any user is doing mass mailing from our server and now our IP is blocked in SpamHaus etc.
these things are happening with me from last 4 months, i request to delist and then after 10 days it''s again got listed !
i read all forums and documentations and spent 1 month but nothing changed ! now i am agree that documentations won't help me in this case.

i want to ask that How can i disable PHPMailer in my cPanel/WHM Server?
Like my clients won't be able to send email using PHP mail function , they requires to use SMTP. i turned on tweak setting of that nobody but nothing happened. tell me any proper solution please. if any client send email from PHP Mail functon then his email will directly rejected !

This isn't serious. I bought a new server with a new IP, we not sent never emails yet.

When my client try to send email to Gmail, Yahoo and other companies receive him without problems. But Hotmail/Outlook block the IP and return this message:

Code:

"host hotmail-com.olc.protection.outlook.com [x.x.x.x]
SMTP error from remote mail server after pipelined MAIL FROM:email@email.com SIZE=1797:
550 5.7.1 Unfortunately, messages from [x.x.x.x] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [.eop-EUR01.prod.protection.outlook.com]"

WTF!!!, this is frustrating. How can happens this if we never used this server and have a new IP. I did test with many blacklist tools and the IP is clean.

Hotmail/Outlook need disapear, they are blocking IPs for nothing.

Does anyone know of any providers that offer dedicated servers in Amsterdam that can provide connectivity to the Equinix Cloud Exchange?

So what would you say is the most cost effective provider with a SSD Dedicated Server? I want it to maintain small business webpages in a WHM account with Cloud Linux

Hello,

What do you consider appropriate maximum CPU load for PHP-FPM server with hyperthreading on and off?

With hyperthreading off, I consider the load linear, and consider about up to 70% safe, with a 30% safety margin.
With hyperthreading on, I noticed with experience and on prior google searches that the load % does not go up linearly and increases more rapidly at high values, so I consider up to 50% safe, since at above 50% the percentage increases more rapidly than under 50%.

But, I ask this because I may be to conservative as I noticed many Cloud autoscaling guides use 60~70% as a scale out threshold, and Cloud servers usually have hyperthreading on.
Personally I had always considered 60~70% dangerous.

Host recommendations needed. Let me start by saying, THANKS in advance for your replies.

I own a (very) small US-based business and my website/email hosting has been with LiquidWeb since they acquired my previous host WiredTree.

LiquidWeb ignored a support ticket yesterday and as my yearly payment comes due next week I thought I probably owe it to myself to at least evaluate my options before it renews.

My biggest priority is knowing I have good managed support when I need it. Problem is, having support tickets linger in the cue for a day or so until I call/chat them and ask when it's going to get looked at has been a pretty constant problem since day one. And it's not like I'm inundating them with support tickets either. My website development has been on hold the past couple years due to personal reasons, so this might be the first support ticket I've even opened this year other than asking them to whitelist an IP because their automated process for that doesn't work.

Looks like I'm paying about $2,400/year for a Cloud Dedicated server and $800/year for a second smaller plan (old WiredTree VPS plan).

The main server appears to be 8 core (Intel(R) Xeon(R) CPU E3-1271 v3 @ 3.60GHz) with a 24/900/5 config (I think). I'm not currently taxing the box at all; it's a total overkill in all regards. One downside to LiquidWeb is at the time I moved this server from a VPS to this plan I was kind of forced into a much, much higher plan than I really needed because every option in between had the same limited disk space my VPS had and the only reason I needed to upgrade was that I was pushing disk limits.

As such, being able to scale up or down in the future without having to make huge jumps is also important.

As of right now, the second (VPS) server could easily be absorbed by the first. I actually intended to do that a year ago when my bill came due but then life got in the way and it fell through the cracks.

Both my boxes are managed CentOS/WHM/cPanel with Root access. I did not migrate away from cPanel when the prices went up. If there's something legitimately better than cPanel I'm happy to evaluate it, but until then it's the devil I know.

Prior to WiredTree/LiquidWeb I had 2 VPS plans at ServInt. Originally ServInt was excellent... until they weren't. But even after they outsourced their support overseas, I really still didn't have support issues. I left ServInt because my boxes were aging badly and all signs said the company was in trouble. I will also say my brief experience with WiredTree support before they got bought out was amazing.

Before ServInt I was with Inmotion Hosting (originally shared hosting then a VPS albeit without Root access). I will say I have no desire to work with any host that sells shared plans again.

As far as budget is concerned, I can afford what I'm currently paying. Yes I'd love to be paying less although that's not what's driving this search. If I stay with LiquidWeb, I'll migrate the VPS into the Cloud Dedicated and downsize to $2,400/year. If I'm paying less elsewhere, I expect it's because I downsized the Cloud Dedicated server's specs.

When I left ServInt for WiredTree, recommendations from this site caused me to have a short list of WiredTree, KnownHost, FutureHosting and LiquidWeb. I've seen recent recommendations in other threads for KnownHost and BigScoots, so that's where my current short list begins. Any recommendations are appreciated.

Please make some suggestions/recommendations.

I was backing up some servers to Hetzner dedicated server with JetBackup, but it's very slow even with incremental. I see iowait is around 30.00% plus.

The servers I'm backing up have 2Gbps connections, yet having cheap but fast backup storage with a 2Gbps connection can be quite expensive unless I don't know of the good ones?

Ps I already have bare metal backup hosted in the cloud for primary backup which is already extremely fast, and so if too much hassle/expensive can just drop the secondary backup with Hetzner/JetBackup.

I have been looking for a new provider for some time now and Google Cloud crossed my path and I actually enjoy it a lot. Very easy to customize and choose to your preference.

I wonder about the protection though, I fiddled around with the Firewall which seems great but compared to OVH, how is the DDoS protection? Would it cost me money if an attacker launched an attack on me to consume bandwidth which leads to network costs for me? or how does it work? Would I feel any downtime for some seconds or is it like OVH where I don't feel any at all?

Secondly, which Google Cloud VM can compare to i7-7700k 32GB SSD?

Both associated. You can just google w3space and see the hundreds of other posts about this website.

Take money and then just stall delivering your server. Ordered 01/01/2020 still no sign of server. Been onto live chat 3 times and just get told "within a few hours". Not really fussed about the money but just not what you would expect.
