root@mail:~# sudo ufw allow 25,80,443,110,143,465,587,993,995/tcpVisit the domain name you entered before, and you should be able to see the backend of mailcow. Use the default account admin and password to moohoo log in to the background.
Add a domain name
Select Configuration -> Mailboxes -> Add domain on the top navigation bar to add a domain name
Add user
Go to the Mailboxes page again, select Add mailbox and fill in the relevant information.
At this point, you should be able to start sending emails. Try sending a letter via SMTP with the above information!
To access mailbox go to https://mail.yourdomain.com/sogo and enter username and password.
Create the DKIM key
On the mailcow web page, configure -> Administration -> ARC/DKIM keys, add a dkim, Domainfill in xxx.xxx, Selectorfill in dkim, and choose 1024 for length (2048 looks like Dnspod does not support), and the generated result is shown in the figure:
SPF record
TXT @ “v=spf1 mx a -all”DMARC record
TXT _dmarc “v=DMARC1; p=none; fo=1; rua=mailto:dmarc@yourdomain.com; ruf=mailto:dmarc@yourdomain.com”And Awesome, Now you can test your MailCow Mail Server. I hope you enjoyed this tutorial for smtp server configuration.
Don’t send a lot of mails directly you will be blocked ! .. . Warm-Up Your Ip Address First.
