Can Aquamail automatically change outgoing server depending on connection type?

[brichman]

I recently started using a "prepaid" cell phone running Android, and installed Aquamail on it.  I was already using it on a tablet I keep at home, so I'm somewhat used to it.  I have the new phone set to use my wifi connection when I'm at home, rather than the cellular network, to save money.  The problem I've run into is that my internet provider's outgoing mail server I use at home won't accept relaying, which is what it looks like I'm trying to do when I connect from work via the cellular network.  I was hoping there's a way to have it choose which server to use based on whether I have cellular data enabled or not.  Any advice?

Yes there is a optional "use this outgoing server on WiFi" in detailed outgoing server setup screens (in account setup).

But it's only visible for "internet mail" and not for OAUTH2 - enabled mail services (Gmail, for example) because well it just doesn't make sense to use a separate server for those.

Now you mention "relaying" - if your account has login / password or OAUTH2 (any kind of authentication) enabled, then it's not "relaying".

Rather maybe your internet provider (cellular provider?) mail server works / it set up in Aqua Mail without authentication? That would cause "relaying" when the device is connected to some other network.

Enabling auth (login / password) for the mail server should work, because the server would now know "who you are" (without relying on your IP address as it does at home, when connected to the provider's network).
