The error messages states your are trying to send through SMTP.dslconnect.co.uk. According to your new providers info it should be SMTP.kinex.net This is hardly the correct settings. What did your provider check and say it was okay? http://kinextel.net/support/configuring-email-program/

That's weird. I spoke to Kinex customer service and they gave me the smpt server information. I just typed it verbatim. I just tried the smpt server you provided and still got the time out message. :/ Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) SMTP.kinex.net timed out. Try again. They checked and said that there could be an issue on Thunderbird's side or an issue with the pc itself? But this problem has only started since we changed ISP to them and had never happened before. Thanks for replying.

What do you have for a username? Your provider is short on full descriptions for email settings but it does say username should be only the name before the @ sign. Do not include anything after that.

If you change the SMTP port to 587 does it work then?

Okay. The error message has now changed to the following... An error occurred while sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server 216.235.225.6 (216.235.225.6:587), connect error 10060.

I got rid of the password after troubleshooting for a bit and interestingly the messages are moving to the 'sent' folder now but don't seem to be appearing in anyone's inboxes.

I sent a couple to one of my personal e-mail addresses just to check.

User name is : [email protected]

If you go back to port 465 and change SST/TLS to STARTTLS does it work?

Your username indicates that you have email connected to a website. Who hosts that? Is Kinex just the ISP or do they host your site and email also?

So I just changed to port 465 and to STARTTLS. New error message this time! Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.Kinex.net was lost in the middle of the transaction. Try again.

The ISP is Kinex. I genuinely have no idea who hosts the e-mail as I've only been here since August last year.

Normally you send and receive through the servers of your email provider. If your ISP is the provider you would use their servers but if the website host is the email provider you would use their servers. I think you need to sort that out to get to a solution.

Cheers. Do you have any idea how to find out who hosts an e-mail address? Aha. This is starting to be very involved and I'm a bit out of my depth.

Oh god. As a result of this I'm now not even receiving emails when I was previously. :/ Is there any way to find out what the incoming server was before I changed it for this?

I believe the michaeljohninteriors.co.uk domain is hosted by 123-reg. They provide instructions on how to set up an account in TB. You should end up with an entry under Tools/Account Settings/Outgoing Server (SMTP) with these settings:

outgoing server name: smtp.123-reg.co.uk port: 465 Connection security: SSL/TLS Authentication: normal password User name: [email protected]

In Tools/Account Settings, select the michaeljohninteriors.co.uk account in the left pane and make sure Outgoing Server (SMTP) in the lower right pane points to smtp.123-reg.co.uk.

michaeljohninteriors.co.uk has two name servers, two mail servers and one IP number.

The name servers are ns.webfusion.co.uk (used by 4,850 domains) and ns2.webfusion.co.uk (used by 5,120 domains).

The mail servers are mx0.123-reg.co.uk (used by 658,000 domains) and mx1.123-reg.co.uk (used by 658,000 domains).

The IP number is 184.168.205.1.

The PTR of the IP number is p3nlhg128c1128.shr.prod.phx3.secureserver.net.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.123-reg.co.uk timed out. Try again.

Having the same issue unfortunately.

Thank you for all your help though. It's very much appreciated.
