Resolved - Postfix on Fedora 29 - Why Can't I Send Mail?
-
Vultr blocks email on all systems by default. To send outbound from Vultr you must always open a ticket and request that port 25 traffic be allowed.

Thanks. I will start there and see if that solves my problems.

I am setting up Postfix on Fedora 29 to send notifications for dnf-automatic and fail2ban. This server is running on Vultr and I am trying to send from DomainB.com to DomainA.com. DomainB is a new domain that hasn't been used for anything and DomainA is our main email domain, setup on Office 365.
In the postfix logs, I am getting connection timed out -
Mar 18 17:19:41 HOSTNAME postfix/qmgr[4085]: EEE853EE90: from=<[email protected]>, size=465, nrcpt=1 (queue active) Mar 18 17:20:11 HOSTNAME postfix/smtp[9703]: connect to domainA-com.mail.protection.outlook.com[104.47.48.36]:25: Connection timed outI have tried disabling firewalld, but still have the same issue. Not sure where the hangup is. Any suggestions on what to check?
I just went through this on Friday

This is an account level block. So, you only need do it once per account.

Oh good. That explains why the systems administrator (his title) referred me to the account management team.

With ours it is per machine. Every new machine we request it.

Never been referred before. You just submit and minutes later it is done.

That is not what their policy states.

Weird, not how it works for us in practice.

From Vultr account management - I included most of this in my initial request -
Hello,
Thank you for contacting us. We have received your SMTP Unblock request. However before we can remove this block, we must verify additional information.
Please reply to this ticket with the following information:
- The business name and organization URL(s) under which you offer services.
- Describe, in as much detail as possible, the nature of the emails you intend to send.
- The volume of email that you plan to deliver on a daily/monthly basis.
We need to know this information to make an informed decision regarding your account settings.
Please let us know if you have any questions.
Kind Regards,
Kanita Z.
Customer Support -
My reply for the 2nd and 3rd questions.
- The emails are only used for alerts/notifications to our IT department from a handful of monitoring apps/services (fail2ban, dnf-automatic, etc) on the vultr server instances we will be using.
- Very light volume. Again, these are not going to be used as a dedicated mail server; all mail generated from our Vultr instances will be delivered to our Office 365/Exchange online account.
Plus, I asked this question-
Are you able to open 25 for our entire account, or will I have to request this for each instance?
-
No real argument with their follow up questions.
Those are good to get documented. Even if they don't mean shit.

Vultr should have a form for this specific request. I have lost a day waiting for them on the back and forth. They close at 5 ET. First, they give you to tech, then tech reviews it and sends it to account management, who then has to ask you the questions, then you wait based on your reply.

I've never had that happen before.

Well, maybe they changed the procedure to make it more convoluted and less efficient.

I agree. Spammers make everyone lose

Could be. I've done it recently. But not REAL recently.
