Title: Error 530 Sending Email
Post by: bryce on October 18, 2013, 10:28:35 PM

I have a program which sends emails and it works perfectly when I am connected to the Internet through my normal router on the desktop.

However, as soon as I connect using a 'Mobile Wifi router' I get the following error when attempting to send an email:

NetTalk Object Error

A network communication error has occurred.

Error = Error n this message.  The remote Email (SMTP) server sent error = 530 Authentication required State = 74 Will try and send next email.

Error occurred in function: NetEmailSendProcess

The connection to the Internet via a browser works fine but the email sending doesn't.

Can anyone give me any ideas what this might be?  I am a bit perplexed as nothing changes except the router.

Thanks.

Bryce

Hi Bryce,

If your mobile Wifi Router connects to an ISP, rather than your own infrastructure, you might find it is a security measure used by the ISP. Many "domestic" ISPs will block all SMTP access except for their own STMP Server. This limits the damage a Mailware/Virus Bot can do.

If so, just change your STMP to that recommended by the ISP (and you can probably turn off authentication) and it should work.

Regards
Bill

Bill,

Thank you for that information.  I was totally at a loss.  I shall do what you suggest and then hopefully be up and running whilst mobile.
