All info I can find regarding hostgator say to use : SMTP

• Port: 465
• Connection Security: SSL/TLS

Please Edit the outgoing server to use those ports.

click on all 'OK's

Exit Thunderbird Wait a while for background processes to complete

Make sure Firewall is not blocking port 465 Start Thunderbird

Its same. Nothing happened. Changed to 465 SSL/TLS.

Mail is delivered from thunderbird but can't receive on recipient email account.

Try changing your IP address.

Sounds like mail is being sent but receiving servers are not allowing it to be delivered or it may be appearing in Spam instead of Junk.

Try changing your IP address.

Do you know if recipients have checked their webmail account spam folders ?

The MailSpring app is installed on same machine. It is sending mail fine. But when sent through thunderbird, it never reach the destination address. So no point changing the IP here. I have a fix IP in office. No mail is going into recipient spam.

Is there any tracing that can be done when thunderbird handshake and deliver the message with destination email server?

Test sending to me as I'm not gmail etc. Could you try to send me an email: mail at anje dot co dot uk Subject : sent via thunderbird

Mail is sent.

Hi I can confirm that I received two emails. the one from mailspring went to Inbox The one sent via thunderbird auto went to my Junk folder.

I think servers are using a product like spamassassin and picking up your email as spam and either putting it in Spam folder on server which POP mail accounts would not see downloaded or the server is removing it and not puttin it in the account webmail.

The only difference I could detect in the email source code was in the received: from mailspring email had 'helo=PC name' thunderbird email had 'helo=[IP address]'

Will send you email which will show you the two different lines.

So located something of interest in bugzilla https://bugzilla.mozilla.org/show_bug.cgi?id=279525 comment 144 I just looked at what Linux FC9 does, and indeed if your hostname is set as FQDN, TB will indeed send that instead of the IP address in the HELO.

Suggestion: Check your FQDN on computer.

Hope this info helps.

Thanks for looking into it.

How do I fix this FQDN in the linux box?

I do not have a linux machine, but I've found some good info at these links.

• https://www.computerhope.com/unix/uhostnam.htm
• http://efod.se/fqdn-on-linux/
• https://askubuntu.com/questions/863132/should-one-use-fqdn-in-etc-hostname-instead-of-hostname
• https://techjourney.net/how-to-set-change-hostname-fqdn-fully-qualified-domain-name-in-rhel-centos-7/

I have the host settings in hosts file for local host.

127.0.0.1 localhost 127.0.1.1 gurupak-PC 127.0.0.1 gurupak-PC #just added this line for testing purpose for TB

gurupak@gurupak-PC:/etc$ hostname gurupak-PC

gurupak@gurupak-PC:/etc$ hostnamectl status

  Static hostname: gurupak-PC
        Icon name: computer-laptop
          Chassis: laptop

How will thunderbird provide the right value for HELO?

Send me email - just like before from Thunderbird and I'll see whether it gets into Inbox and I'll check the HELO.

Mail sent. Let me know if you don't receive it.

I have able to change the HELO in thunderbird

HELO: gurupak-PC that MailSpring is sending.

But still the email is not received in the gmail account.

Is there anything else to be set here?

Not received anything so far. If you update changes, then send me email and I'll watch out for it. do not worry if you need to repeat sending email.

https://techjourney.net/how-to-set-change-hostname-fqdn-fully-qualified-domain-name-in-rhel-centos-7/

looking at line: Edit /etc/hosts file, and enter a new line with the IP address, FQDN (Fully Qualified Domain Name) and hostname of the system. For example: 192.168.1.1 server.techjourney.net server

http://man7.org/linux/man-pages/man5/hosts.5.html another example:

# 127.0.1.1 is often used for the FQDN of the machine

127.0.1.1 thishost.mydomain.org thishost

so you could try 127.0.1.1 gurupak-PC.emergentsoft.com gurupak-PC

Changed the hosts with new value and sent you email.

127.0.1.1 gurupak-PC.emergentsoft.com gurupak-PC

Not received email.

re :

1. 127.0.0.1 localhost
2. 127.0.1.1 gurupak-PC
3. 127.0.0.1 gurupak-PC #just added this line for testing purpose for TB

When you added the last line emails stopped being received. Perhaps this causes a conflict with the localhost in first line. Suggestion: in the third line shown above, you change the '127.0.0.1' to say your IP address which was used by thunderbird in the HELO. I sent you an email which showed that IP address which had been inserted instead of 'gurupak-PC'. Then try to send me email.
