Hello, On my server running more domains with email service. My problem is, i can recive and send emails just with my primary domain. I think there is somthing wrong whith my DNS entries. Primary domain: swapon-group.com has address 93.174.165.4 swapon-group.com mail is handled by 10 mail.swapon-group.com. secondary domains: swapon-group.ro has address 93.174.165.4 swapon-group.ro mail is handled by 10 mail.swapon-group.com.swapon-group.ro. cci-ciceu.ro has address 93.174.165.4 cci-ciceu.ro mail is handled by 10 mail.swapon-group.com.cci-ciceu.ro.
Can you see the arriving e-mails on email server logs? Those domains you show have different MX records. If e-mail for them should all go to the same server, the MX records should be identical. My signature has link to e-mail setup tutorial.
No, I can't see the mails in the logs, the MX records are identical. On my mailserver i have an A record with mail to IP and an MX record with domain.com to mail.domain.com The client dns entries are following by all of my clients: mail 3600 A 93.174.165.4 swapon-group.ro. 3600 A 93.174.165.4 www 3600 A 93.174.165.4 swapon-group.ro. 3600 CAA 0 issue "letsencrypt.org" swapon-group.ro. 3600 MX 10 mail.swapon-group.com swapon-group.ro. 3600 NS ns.swapon-group.com. swapon-group.ro. 3600 NS ns1.swapon-group.com. swapon-group.ro. 3600 TXT "v=spf1 mx a ~all"
Changes in DNS may take up to 24h hours to propagate, so it won't work instantly after your change, you have to wait some time and then try again.
