[nimesh.dev]

Hello,

My server is on digitalocean (1GB RAM) ubuntu 18.10 + vestacp with exim + dovecot.

I am able to send the emails but i am not being to able receive single email.

I tested on mxtoolbox, everything seems fine. I am lost how to solve it. Please help me.

Without information like your mail domain it's impossible to help, e.g. mail.yourdomain.com

[nimesh.dev]

I just checked my details here https://mxtoolbox.com/domain/bfm912.com/ and every thing seems ok.

I don't know why it is happening.

Please help me.

You should be running MX lookup https://mxtoolbox.com/SuperTool.aspx?ac ... n=toolpage

No DNS record found, also ehlo gives

Code: Select all

ehlo mail.bfm912.com 
250-bfm912.com Hello 96-42-56-223.dynamic.dsl.as9105.com [96.42.56.223]
250-SIZE 52428800
250-8BITMIME
250-PIPELINING
250-AUTH PLAIN LOGIN
250-STARTTLS
250 HELP

A correct response would be similar to this,

Code: Select all

ehlo mail.bfm912.com
250-mail.bfm912.com Hello [96.42.56.223]
250-SIZE 37748736
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-STARTTLS
250-AUTH NTLM
250-8BITMIME
250-BINARYMIME
250 CHUNKING

Check DNS/MX record.

How to fix it, please help me i am a beginner.

[nimesh.dev]

Also i have same dns not found error on another server https://mxtoolbox.com/SuperTool.aspx?ac ... n=toolpage

But everything works fine here.

Is DNS external, i.e. managed on the website you purchased the domain from?
If it is go to DNS settings and look for an MX record, it should start mail.bfm912.com and end with the ip address of your server.

[HenrysCat]

Try this test https://www.checktls.com/TestReceiver

[nimesh.dev]

DNS is managed from vestacp dns manager not domain manager.

What should i do?

[HenrysCat]

If you run the checktls.com test from above you get "Cert Hostname DOES NOT VERIFY" error, this will prevent certain domains from sending to your email, usually hotmail/outlook is fussy about certificate matching, your certificate must contain mail.bfm912.com and bfm912.com.
