email server not sending mails

[billy_bazooka]

I am following this guide on vultr: https://www.vultr.com/docs/an-openbs...d-and-rainloop to setup an email server on openbsd.

I fire up thunderbird. I can receive mail just fine. But I cannot send mail. Nothing happens when I send mail.

Email seems very complicated. Much more so than web server, I dont know how to debug this - what is my first step to solve this?

here is my smtpd.conf, with my domain name switched to "example.org" of course:

pki "mail" cert "/etc/ssl/mail.crt"
pki "mail" key "/etc/ssl/private/mail.key"

table aliases file:/etc/mail/aliases
table credentials passwd:/etc/mail/credentials
table virtuals file:/etc/mail/virtuals

filter "rspamd" proc-exec "/usr/local/libexec/smtpd/filter-rspamd"

# To accept external mail, replace with: listen on all

listen on all tls pki "mail" hostname "mail.example.org" filter "rspamd"
listen on egress port submission tls-require pki "mail" hostname "mail.example.org" auth <credentials> filter "rspamd"

action "local_mail" mbox alias <aliases>
action "domain_mail" maildir "/var/vmail/example.org/%{dest.user}" \
    virtual <virtuals>
action "outbound" relay

# Uncomment the following to accept external mail for domain "example.org"

match from any for domain "example.org" action "domain_mail"
match from local for local action "local_mail"

match from local for any action "outbound"
match auth from any for any action "outbound"

Not really sure what to do?

hm.. it seems maybe vultr blocks outgoing mail...

Are you sure you server does not send e-mail? Maybe it sends, but is rejected by other servers?

By default, Vultr blocks outbound SMTP from their networks. A service ticket must be opened to request it for your server.

[billy_bazooka]

Yes, its the vultr. Blocked email.

They did not want to open it for me.
You know what - the only reason i bought a vultr vps was because of their "openbsd mail server" article. And smtp is closed - and they said they will review my request in a month. And that my account cannot lay dormant.
Jeez - downright disgusting.

I've previously had no problems getting outbound destination port 25 opened by Vultr. The first time, I recall it taking about 15 minutes from opening a ticket to getting the port opened. The second time I recall that they emailed me a form to fill out and return, telling them that I was going to use it for limited personal Email, that I wasn't a spammer, that I wasn't a bozo, and that I'd take responsibility for my actions. The entire turnaround from open ticket to form to open port was probably 60 minutes.

To follow-up again, Vultr policy must have changed. I went through my tickets looking for my most recent request, which was in 2019. At the time, Vultr responded with the following request. Note that the PDF referred to below is no longer a valid link:

I have been using Vultr for several years. At first I only ran a webserver that sent transactional email, and never an issue.

Later I moved my mail server over and never an issue.

I have been using Dallas DC.

Are you by chance using a newly purchased domain? That might play into taking a longer time for them to approve.

OTOH, their IP address reputation seems solid.
