Rainloop can receive mail, but does not send

I have SSL for the mail server. Messages show in the sent folder, but I have sent to gmail and outlook email accounts and it has not been received.

From those same gmail and outlook accounts I have sent a email to myself (rainloop acct) and I received it. If I hit reply, the message shows as sent on my end but the receiver will never get it in their inbox.

If someone can please explain in detail what I am doing wrong and what settings I should change. I can see more screenshots if needed. Thank you in advance.

detail: ?

cyberpanel version ?
do you using cloudflare ?
domain name ?

if that info (domain name) is secret (privacy) please PM me the domain name

Make sure ports needed for mail is opened from service provider too not just your own firewall.
By default almost all VPS providers block ports for sending mail, you need open ticket request open ports.

I am hosted on Hetzner cloud, so contacting them would not be helpful for server.

CyberPanel v2.3.

Unfortunately I do not have the ability to send you a direct message.

i just read your domain name at PM,

now… what you want to do

outside ====> your mail server = success
your mail server ===> outside = failed ?

like that ?

delete the emailuser@yourdomain.tld
recreate
then re try:

what the complete version

So I went to /email/deleteEmailAccount, selected my domain, and then deleted the specified email address. I then went to create email /email/createEmailAccount, and remade it. Access email (had the same emails in the sent folder btw) and tried to compose again and it still did not work.

lets we start with cyberpanel version
what is your cyberpanel version

ok… let test this
forget your old email then create a new one… slow down… 1 by one…
after create
do not do anything except login to rain loop…
screenshot here or inform here the folder (inbox sent etc etc)

i will be here for next 3 hours (maybe more lol)… dont worry

That is what you need to do. Open ticket to their support and ask them open mailing ports.
You need to tell them how you use your mail server that you ain’t spammer etc…
You ending doing days trouble shooting if you wont check very first is VPS provider allowing use those ports. Its not enough you open ports from your own firewalls. Try this port check insert your server IP and port 25 to see is it open.

By default pretty much all VPS providers block ports for sending mail. To prevent spammers/scammers.

I used that website, the port is open it shows.

Ok I deleted the email yesterday. I just recreated it now.

Now I am creating under domain.com. Should I also be doing something with the mail.domain.com ?

Sending mail still does not deliver, it just sits in my sent folder

What mail log tells you? Check all DNS records are correct screen shot your A, mx and txt record here too.
If ports are open and DNS set right mails should work.

You can see those screenshots at https://imgur.com/a/90zYwvg . Unless you need screenshot from my domain registrar?
