SMTP Outgoing. Please answer this once and for all for me.

[Resolve]

Ive always heard different answers to this question so would just like confirmation on this.

Currently setting up a vodamail account in Outlook. The outgoing mail server here depends on the current ISP I am on?
So every time I switch to a different ISP I must go change the settings?
There is no way around this?

The reason I am confused is because Ive got a gmail account as well as a personalized business email account Ive got registered at Hetzer.
Both of them work fine in Outlook no matter which ISP I am on.

As long as you auth with the SMTP server it should not matter which connection/ISP you are using.

Ohh so its that simple? Because I just got of the phone with a representative from vodacom. And they made it clear to me there is no way I can use my vodamail account on different ISPs. I turned on auth(Use same settings) And it works.
So thats why I was confused. Apparently they dont know what they are talking about.

I can't comment on Vodacom's tech support (the Stortech guys who look after their network infrastructure are very good - no clue about the consumer side) but one of the other ISP's had a tech ask me to check if I could ping 127.0.0.1 from a machine used to troubleshoot an internet connection.
They walk among us!

Easiest way to solve this problem. Ditch Vodamail. I once was on vodamail, I bit the bullet and just got rid of it. Emailed the most important people my new address and just ditched it.

See,the reason it's so confusing is because there are different implementations on each network

Most/All ISPs only allow SMTP-relay through their own servers for their own IP ranges - unless using SMTP-auth
Some ISPs redirect outgoing smtp traffic to their own SMTP relays - this allows for them to prevent botnet type traffic blacklisting their IP ranges. This however would make SMTP auth port 25 requests fail unless they accept-all
Most/All ISPs allow port 587 SMTP-auth traffic to go unmolested
Few ISPs support SMTP-auth
The general most-compatible method is using a private smtp relay with smtp-auth on 587,that would cover just about every variant (these relays generally cost money or need to be with a specific provider like GMail)
