E-Mail / Can't send email
« on: June 26, 2020, 06:32:43 PM »
Good day,

I hope someone can help.

I can receive email but can't send. Internal sending from one to another email on my server works though.

Have set up SPF, DKIM and DMARC and I get a green light at MX Toolbox. New emails can even be set up in a client like Thunderbird without error.

I have contacted my ISP and they initially said the SMTP port was blocked and opened by them. I tried and still nothing. Then my ISP said port 25 was still blocked and they unblocked it. But still not working.

This is the Mail Queue error message:

Queue reason:
00EBD6248E     1482 Fri Jun 26 13:54:32 

(connect to alt2.gmail-smtp-in.l.google.com[2a00:1450:400b:c00::1a]:25: Connection timed out)

                                       
Here is the server's mail log:
