i have installed Mailserver packages and configured. i tried to send email on internal user’s mail id, they are working perfectly. But when i changed my mx record and then i tried to send email from gmail to our mail server user’s mail address then its showing “undelivered Address not found”.
Is there IMAP issue or any other issue please let me know, if any other setting required let me know.
Firewall and DNS MX record set perfectly. Crosschecked multiple times. But Same issue.
Is there any other setting on server or its bug of dovecot in NS7 ?
SMTP is working fine. But not receiving emails, imap issue.

Isn’t this just something of replication? MX record not yet known by google smtp…
If you resolve the MX record does it point to the external IP address of your server/LAN?
If i am sending email from GMAIL or LIVE.COM etc. I am unable to receive from outside.
If i am sending email from locally then its working. Internal users can send and receiving emails in their INBOX.
This is very strange issue. Please help.
To be clear: you need both: an A record and an MX record.
If you want to use something like mail.domain.tld you need to set an A record to the IP address (or CNAME to an A record) for mail.domain.tld and an MX record to mail.domain.tld
ok
Also getting some failed logs in /var/log/messages

A mailserver does not need a Samba4 or LDAP domain to function. However, this can be a problem for NethServer to work properly with different users.
Do I understand correctly you use an Aruba VPS? How did you configure the bridge for the Samba4 container? This is a different problem than your mail issue. It probably should get a different topic. I can split this off and create a new topic for this if you want.
