SMTP can't send mail after I move server.

Nodeloc

The issue

Today, I migrated Flarum from one VPS to another. After the migration, I am unable to send emails normally. I can confirm that there is no issue with the email server and my local ports are fine as well. However, I'm currently unsure of the cause of this issue.

I can connect the smtp server correctly.

# telnet smtp.qiye.aliyun.com 465
Trying 47.246.64.75...
Connected to smtp.qiye.aliyun.com.
Escape character is '^]'.

The error log.

Nodeloc who are you hosting with? Some companies require you contact their support to enable outbound email on new servers as a measure to prevent spam.

ernestdefoe

clarkwinkelmann I can confirm this as Hetzner blocks the ports but after a month you can submit a request to have the ports unblocked.

Nodeloc

clarkwinkelmann Thanks for your reply. How can I check if it's server's problem. Thank you. This VPS server is created by myself. And in my another VPS server, with WHMCS , SMTP is works well with smtp.qiye.aliyun.com.

luceos

Nodeloc you can't know. The ISP does this. As you haven't shared the provider of your VPS, it would be a wild guess. So the best thing is to contact them or read through their documentation/support pages. It is very unlikely caused by any other party or software.

Nodeloc

luceos Thank you very much. I will try to contact my provider to see if there are any restrictions.

Nodeloc

Follow-up: It has been confirmed that the service provider blocked the port. I have contacted them to open it. Thank you all.
