I have a server running Debian. I installed iRedMail, but now I want to access the mailserver externally (receive and send mails). I have to set up DNS records for that, but I can't seem to figure it out correctly.

Can anyone help?

Thanks.

Currently using iRedMail which installs an SMTP and IMAP server. I created a few e-mail addresses. They can send e-mails internally without any problems. Now I want to take it all externally. All the e-mail addresses on this server should be able to receive e-mails from external addresses (hotmail, gmail etc) but also should be able to send out e-mails to external addresses. I ran the default installation, that's it.

Current records:

localhost.domain.com        A       127.0.0.1
domain.com              A       XXX.XX.XXX.XX
www.domain.com          A       XXX.XX.XXX.XX
ftp.domain.com          A       XXX.XX.XXX.XX
domain.com              TXT         "v=spf1 a mx ip4:XXX.XX.XXX.XX ~all"
domain.com              MX 10   XXX.XX.XXX.XX

please clarify, you need DNS to connect easily, or DNS for external mail delivery? – Tim Jan 13 at 16:24
I'm sorry. I am trying to reach the mailserver externally. The server is in a datacenter. I would like to send out and receive e-mails from my computer at home. – Roel Jan 13 at 16:32
Can you provide information in your question about what you've attempted, and how the records are configured currently? – Shane Madden Jan 13 at 16:35
Added to the question. – Roel Jan 13 at 17:26
Is a firewall running? Is public DNS able to see your updated dns records? – becomingwisest Jan 13 at 19:19

Assuming both the IMAP and SMTP server reside on the same IP address, you can create an "A" record to point a name to the IP address, or use a "CNAME" record to create an alias to an existing record.

Assuming the public IP address is 10.8.0.5 an "A" record would look like:

mail.myserver.com A 10.8.0.5

And a "CNAME" record would look like:

myexistinghostname.com    A    10.8.0.5
mail.myserver.com    CNAME    myexistinghostname.com
