[Linux: using alpine mail client and ISP SMTP] From:, Reply-To: and spam filters.

Hello. I'd like a better understanding of what I'm doing to myself with my
my E-mail set-up... {Don't worry I won't actually list addresses here}

I'm not sure this is the correct place for this question, But I couldn't find a more suitable one.

A long time ago I used dialup. When I upgraded my Internet access to
broadband from a provider that doesn't offer dial-up logins for when their
customers are not at home, I decided to keep my old primary email account
with a few hours of dial-up service included for a very low price.

This provides me with continued access to my long standing email account.
{I liked the idea of not having to ask people to update their
address books nor did I want to have to update all my mailing list and forum
} AND it also leaves the dialup option available in case I'm going
to be away from home long enough to bother.

But, as it happens my broadband isp and the dialup one don't quite play
nice with each other. For example: excluding the {Yuck}webmail
interface I can't seem to use the dialup's smtp server unless I sever my
broadband connection and actually dial up. So I set my dialup inbox to forward
everything to my broadband one. And generally use only the broadband servers.

However, I was informed once that using a From: field from the dial-up
on E-mail actually sent from the broadband providers SMTP caused a lot of my
email to get hung up in various spam filters.

It was suggested that this wouldn't happen if I put the Broadband email in
the From: field and simply put the dial-up one in Reply-To:... However for
assorted reasons {Including all those mailing lists etc...} I didn't
want to do that.

But I couldn't get anyone to tell me if doing the reverse: putting the
dial-up isp email account in the From: field, and putting the broadband isp
email account in Reply-To: {While actually sending through the broadband
providers SMTP} will likely be good enough to prevent most spam traps
from flagging my mail as spam?? At least not on the basis of: the From: address not
matching the actual sending domain???
