Configure Mastodon to Use Zoho ZeptoMail for SMTP Email

It's also temperamental. It will just stop working.
ZeptoMail? I've never had that happen.

@PhlipElder said in Configure Mastodon to Use Zoho ZeptoMail for SMTP Email:
We have an internal IIS or Exchange based SMTP server that we set up for this. It's just too painful otherwise to figure out.
We never do that because it's too temperamental. If you get blacklisted or anything, all it takes is your datacenter getting listed by some random group and suddenly O365 blocks you. We do this with Postfix which is faster, easier and more stable than Exchange (in places where we deal with Exchange we typically put Postfix in front of it for safety) but only to relay to ZeptoMail or SendGrid or Mailgun because that's how you make transactional Exchange or Postfix the most reliable.

I have had these things. They never seem stable to me.

I use Postfix, typically on Fedora, I don't have problems then.
I setup it up on Vultr and restrict the IP that can connect to the company offices.Sorry, poorly written English.
Mastodon is temperamental with SMTP.
We have IIS SMTP and Exchange set up across the board (our clients are cloud averse) with Exchange being fully stable once in.

All of our mail servers are properly set up with a SmartHost, SPF, and DMARC. We don't have any reputation issues. That's a 2000s kind of problem.

No, it's current. Microsoft blacklists entire datacenters still. There's a lawsuit in Illinois about it that they lost. It's a very real thing still that RBL are used by the majors (like Microsoft, but not Google) and used to shut down entire ISPs and IP blocks. I've been brought in to help providers with these issues, it's a huge legal problem and if you don't get hit with it, it seems like it doesn't exist, and if you do get hit, it seems like there's no recourse (hint: there isn't.)

Like from version to version? What does it do? It's sad that they've not implemented API calls yet.

MS blocks entire IP blocks based on ISP ownership of said IP at the ISP request. It is fucking horrid.
Example (a Comcast IP): https://check.spamhaus.org/listed/?searchterm=69.139.101.133

They do, but they also block ISPs at the request of OTHER ISPs!! It's nuts. They are super willing to block anyone and everyone and there's no process for fixing it.

We're dealing with a client who has their site hosted in a Yandex.RU data centre and guess what? Yeah, some putz between their web server and ProofPoint has a sinkhole because Ukraine. The web server can e-mail @Outlook.Com because they have servers around the world but not ProofPoint.
We've had lots of issues over the years where one midbone/backbone provider either shapes or blocks packets from another because they're in a contract dispute. Poof. Packets gone.
