Help! (Home for newbies)

I installed Roundcube works perfectly fine but whenever i try to test my smtp anywhere else it says No host found

Mail.vendocard.xyz
doesn’t exist
I don’t know what idid wrong! please help , I can’t use SMTP but roundcube and other build in aps working fine to send email. I created a MX record for mail.vendocard.xyz with priority 5 , Please let me know am getting this error

An MX record is not an address record. You also need an A record for that name.

3

Try domain.tld instead of mail.domain.tld.

Did made a A record but still doesn’t help , I can’t use the SMTP option but roundcube and SquirrelMail works perfectly fine please help

How its not working

6

What’s not working? What did you enter for hostname, exactly?

7

I was trying to use the SMTP credentials and it always says Host error! I tried mail.domainname.xyz
domainame.xyz but didn’t work! Am gonna make a new one and try again

Ok, after you create the new virtual server, say xyz.tld, use the hostname of your Virtualmin server (say hostname.tld) in the email client. I think that might work.

As Joe had pointed out earlier, mail.domain.tld (MX record) won’t work

12

what should I do? everything works if i use roundcube , But i can’t use SMTP it keep saying the same thing! SMTP HOST error! doesn’t work Why bro help

13

does that mean i need a different domain?

14

You can use any name you want. DNS no longer appears to be the issue.

This looks like maybe a missing PHP module? What mail client is producing this error? It’s not anything I’d be familiar with (I don’t know anything about PHP and mail), but that needs to be in the conversation.

Trying to add it in Mailwizz! I even triedd using just simple smtp Tester , it says

Mailbox unavailable. The server response was: Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
used even this : https://www.smtper.net/

its maybe Virtualmin Smtp hostname or port problem. Please bro help! I used roundcube works perfect but whenever i use SMTP port and credential it produce error!
