I am paying fees to my bank and they state they want to be contacted
by e-mail. So I expect them to accept my e-mail (and answer if needed).
The choice to run your own server means you’re choosing to handle your own
deliverability. In some cases, that means sending to specific places isn’t
viable. We ran into a similar problem trying to send attachments (that were
asked for and necessary) to a government department. Our tiny little mailserver
couldn’t. We fell back to a gmail address and got the process handled. Was it
frustrating? Eh. It was kinda annoying. But it wasn’t a huge barrier.
In another recent case one of the major filtering provider started bouncing
mail from us. Not because our MTA IP was blocked, but because they were doing
some 2nd received line filtering and the IPv4 NAT our cable modem goes out was
blocked. We followed the instructions in the bounce message and it was resolved
in < 24 hours. Now, was it a mistake or was one of our neighbors spewing a
bunch of spam / virus out through the NAT? I don’t know. In any case, it was
resolved.
I’ve actually found that filters are getting more friendly to small servers.
The reality right now is: if you make the choice to run a mail server of any
size you’re going to have to deal with deliverability issues. That’s part of
what you’re opting into when you decide to run your own server. There are
people out there who have spend over a decade providing deliverability advice,
tools, and resources all for free.
Filtering isn’t going away. If spam went away tomorrow, filters would still
exist. This is just the reality any mail server operator needs to deal with.
Don’t like it? You can outsource it to a 3rd party who will handle that for
you.
