Unable to send email on VPN

[signda]

When I am logged into my VPN (on an Sydney server) the TPG mail server rejects my emails from Microsoft Outlook.

I get

Task 'XXXXXX@tpg.com.au - Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Is this a policy of TPG or a problem?

It is very annoying having to shut down my VPN just to send an email!

Thanks,

David

Hi @signda . Did Outlook ever work when using VPN?

What port and security setting are you using?

If using port 25, try port 587.

If the issue still persists, we suggest to raise this to our postmaster for real-time test and investigation, you can send an email to postmaster@tpg.com.au

Wow! No it's never worked but changing the port id sorted it straight away!

Many Thanks!

Why 587?

@signda . You'd have to ask the VPN provider why they block port 25.

In Outlook, you can try a security setting of STARTTLS for encryption for sending and receiving.
