I did some digging and the closest thing I came to information regarding this issue was this hostgator support document. I've tried that and the messages being sent by my server (coincidentally enough, run by hostgator) are still getting rejected even after using that advice.
How did you lot get around this?

The project I'm working on is a newsletter builder, and I'm on its final steps. Now I need to verify spf dkim and dmark (which I don't know what they mean or how they work). Then I also need to check if my email is considered as spam or if any of the news contains spam (separately). I tried to read the documentation of 2 great spamcheckers (spamassassin and rspamd) and I couldn't understand anything about how they are supposed to be integrated on my project. I think all my problems are due to my lack of knowledge related to emails/email servers and stuff related. I'd really appreciate if someone could enlight me about what are the steps that I need to do, if I really need to setup an email server to test this out and how to do it etc. etc. I'm really in the dark here. I know the enterprise I'm doing this work for already was sending emails from their domain but I don't think they gave me access to that.
The following link may be useful to you, it's a document of iRedMail (an open source mail server solution):
https://docs.iredmail.org/setup.dns.html
You don't need to know what iRedMail is, just check the introduction of each dns record.
For me, these introductions are enough, if you want a more detailed introduction, wikipedia and official website may be more useful
For checking spam status and dns records such as spf, dkim, etc., setting spamassassin or rspamd by yourself may be complicated, but there are many free services available.
I often use the following (I have my own mail server, so I sometimes use these services for testing):

Our IP address recently got listed on UCEPROTECT-1 as a potential spam address, and we aren't able to figure out how to stop this. According to their website, UCEPROTECT-1 listing happens when: IP's get listed in Level 1 automatically if they either try to deliver e-mails to spamtraps or if they are involved in port scans or probes or any kind of attacks against our servers
Some research online suggests that the only way to ensure it doesn't happen again is to find out what is triggering these spam traps and plug them.
Any idea how we can go about looking for what is triggering these automatic listings? Any help would be appreciated!
Some background:
We use GSuite for our email servers, wix.com for our website, and namecheap.com for our DNS.
We'd originally paid to not be listed in the UCEPROTECT-2 and 3 listings but were automatically removed as soon as we got listed under UCEPROTECT-1.
I don't know how G-Suite works but in general check
logfiles of the outgoing e-mail servers for days with "strange" recipients patterns or for more e-mails than on other days
if your domain is listed on other blacklists, maybe that is giving you other hints
The problem is: if you are using the outgoing e-mail servers from Google and some of them are listed on UCEProtect (because other G-Suite customers are sending spam, mostly without knowing it cause they are hacked), you have little chance of fixing this yourselve. This is not really uncommon, me.com/icloud.com (17.58.63.0/24) is listed at UCEProtect right now too.
I'm aware this may not be the right place to ask this, but I don't know where else and others may encounter the same issue.
I'd like to have an aggregated view (or an alert) when some recipients in my contact list don't receive any of the emails my app sents. Is this possible?
I checked on the alert thing in the docs but it doesn't seem to do what I need. Although this seems like a pretty common need and there may not be necessary to setup webhooks and own app logic to handle this, wouldn't it?
Thanks
I have also faced same issue with cPanel and many other providers like Mailchimp. This usually happens due to Empty Subject due to which Cross-Server Contacts may not happen. Also, if you are using PHPmail() or sendmail function instead of SMTP, You need to be using TLS1.2 or TLS1.3 though 1.0 is also supported but many of my E-mails were not delivered so I upgraded to TLS 1.3 . Also, Check if your mail goes to Spam Folder. In that case, increase your Website and Domain Score and Try to rank in Google Safe Browsing. Also, this also happens due to misleading Hosting Provider whose SMTP servers are not setup correctly or Provider send many spam messages due to which, you domain score may got low. I currently use interserver_smtp and cloudmate_smtp collectively for all my clients as interserver deliverablility in India is low and cloudmate works in both texas and india correctly. Try cPanel or Plesk as it has the best deliverability. One More thing, This could also be an issue of DNS. Check your DNS settings if MX records are pointed to MailJet Servers.
I have been sending emails (through gmail accounts and gmail smtp server) to text gateways of various wireless providers and they worked pretty well for years until this year. The messages stopped working for all verizon numbers a few months ago. I didn't receive any feedback as to why it stopped working. It is as if the email was sent successfully and then silently swallowed by vtext.com. I tried to limit the number of recipients per email but it didn't help. I did a lot of searches online but could not find a sure reason what has been changed. I started to suspect that my ip or domain has been blacklisted by verizon, but I have no way to contact verizon support about its gateway policy and whether my suspicion is true. The customer support of the wireless department said he knew nothing about vtext.com and thus could not help. All my messages are sports team related (inclement weather, etc.) and they are not spams.
I'd really appreciate any help on finding out the true reason this stopped working, and who/where I can contact to resolve this. This is very important for my web site.
Thanks!
This is why...
It's all about revenue. If you were using Vtext, good chance you have been blocked by Verizon and they want you to purchase enterprise services. Happened to my company today and this has been a critical part of our system to page work orders out to field technicians that service medical equipment. Verizon has affected patient care, and seem to not care when I asked if they can unblock us just so we can make a strategic transition.
I noticed the same thing recently. When I called care they told me vtext is being decommissioned in favor of messaging+, which to my knowledge doesn't have an email gateway. Apprently your region and mine are gone and the plan is to have all vtext shut down by end of 2016.
Currently looking in to alternatives.
I noticed this, too. However, I've found that the mms gateway still works.

We run a large online community in the Netherlands. Because of that we send a lot of mail to the hotmail email addresses of our members.
Recently we have noticed that not all mail is reaching our members, because we have hit a certain limit or so it seems.
Google doesn't give a solution (yet) but we see a lot of others having the same problem.
Note, We have added (since long) SPF records for our domain, in TXT and SPF types.
What else can we do to tackle this problem?

To add to what bzlm said, hotmail probably isn't rejecting your mails, so much as trying to use rate-limiting to prevent spam. That said, there are a few potential solutions you could use here. You could contact hotmail and see about getting your mailserver exemption status from their rate-limiting. Depending on the size of your community, they may or may not respond to you or be willing to work with you. I suggest this only as the "diplomatic" solution.
Or, you could set up two mail servers; one for hotmail users, and one for everybody else. I know from some of the sites that I run that a lot of people register with hotmail accounts, mostly because everybody has one which they use as a "spam dump" for online services where they don't want to use their real email address. So, as you no doubt realize, the number of hotmail users in your database represents a fairly substantial percentage. Therefore, when you need to send an email, you could determine whether to send it to your normal SMTP server, or your hotmail-designated one. On the hotmail SMTP service, you'd need to add some type of waiting mechanism to sleep a certain amount of time after receiving a 421 response.
The problem with this idea is that the number of hotmail users you have, plus the delay you'll encounter in sending, means that the queue length might very well exceed the number of mails you must send. You could alleviate this problem by setting up secondary/tertiary servers, preferably on other networks... but I'm getting ahead of myself here. At any rate, I did a bit of googling around (as you probably have, too), and this isn't such an uncommon problem, but there is no obvious solution to it.
So likely, you'll either have to create some type of slightly-unorthodox network workaround, or try the "diplomatic" route and contact an organization unlikely to care about your problem. I'd suggest doing both in parallel. :)
421 means that the service is not currently available, and that the client should try again. This could be for any number of reasons, including trying to discourage you from too frequent mailing if Hotmail thinks you might be a spambot.
Why not simply let your outbound smtpd queue the mails and try again?
Why is "not all mail reaching your members"? Don't you try again if you get a 421 response?
EDIT: Do what sqook says.
The only real way to "get around" this is to become a good e-mail citizen. Make it easy for people to unsubscribe from your notifications, establish complaint feedback loops with the major mail providers, remove bouncing e-mails from your list automatically, don't send people e-mails they don't want to receive. Failing to adhere to these simple requirements makes you look like a spammer, and providers like Hotmail will treat you like one.
The mail server IP connecting to Outlook.com server has exceeded the rate limit allowed. Reason for rate limitation is related to IP/domain reputation. If you are not an email/network admin please contact your Email/Internet Service Provider for help.
