Problem sending emails from sons place.

I don't see how changing the port resolves this, all that does is switch between non-ssl to ssl. Anyways SSL should always be preferred.

The right error would be a relay issue, very few ISP return this error due to spam/ddos and there are a few things that cause the problem but the most common is your IP does not match what the SMTP expects, normally the case when not using the mail providers internet.

There is no automatic search for SMTP, so when you use someone elses internet, it does not choose their SMTP server, it just continues to use what was set.

You can solve this by adding your credentials (same as your POP3/IMAP username and password) to your SMTP server, so that you are verified. I don't use outlook so can't say how you do this.

Changing your SMTP settings to the current ISP network you are using at the time will work too since you are on the same network (IP) that will allow you to use their SMTP. This would be annoying and if there is an automatic feature, this would help here.

Use the web based mail client, which has its own method of sending mail, probably still uses their SMTP server but it meets their requirements. Especially considering you had to log in to use it and its their server (IP) that is expected.

Only just got back to this, The questions asked this morning now answered, and Kame has asked the right one

You can solve this by adding your credentials (same as your POP3/IMAP username and password) to your SMTP server, so that you are verified. I don't use outlook so can't say how you do this.

Go into the control Panel - ( large or small Icon View)

Locate MAIL (microsoft Outlook xxxx) where x is the version/date.



Select Email Accounts


Highlight your account - Up Top, click on Change



Bottom Right, click on More Settings



Click on Outgoing Server, Select log on Using


Fill in your user name and password, save.

Should now log in normally from anywhere.


If the account was set up as IMAP instead of pop3 & smtp, you wouldn't have any problems either (normally)

Thanks for reply.

Ok i see have you tried using other browsers say if using chrome try use internet explorer or edge . Also try turn off firewall for test purpose and see what it shows .I think try scan for malware and see for what it shows .

.

because if he was sending on port 25 (at home) , many other ISPs block port 25.
But yep, a few settings could have needed to be changed. port, ssl/tls , smtp authenticate etc etc
No one knew his current setup so ...............

Highly unlikely anymore - pretty much every provider requires authentication (so you would need an account at the ‘current networks’ SMTP server.
Open relaying for all of an ISP’s netblock became a bad idea a while ago now.

Use the web based mail client, which has its own method of sending mail, probably still uses their SMTP server but it meets their requirements. Especially considering you had to log in to use it and its their server (IP) that is expected.

Yes, webmail simply provides a web based interface to your providers IMAP and SMTP servers.
