That's a nice idea, but simply not true. You'll be ok right up until
you aren't, and as a small site you have no recourse to find out what
the problem is.
Such statement is incomplete without some examples.
Judging from your long history of contribution at Debian project,
surely you have some that can be shared with the list.
It's really hard to share specific examples without naming domains, so
no. In general terms, It's almost unheard of to get any kind of response
from the RFC-standard postmaster@ address these days. Most of the time,
the best you can hope for is a bounce (rather than your message silently
going into the recipient's spam box). If you're lucky the bounce will
say something like "sender on blacklist X". If blacklist X is reasonably
well known you can probably verify that the sender is on blacklist X. If
you ask blacklist X why the sender is on the blacklist you'll get no
response. Maybe something misattributed a spoofed email (relatively few
sites actually care about SPF etc so spoofs are still extremely common),
maybe someone hit the spam button accidently, maybe somebody doesn't
like your ISP, maybe they don't like your country, who knows? At that
point you descend into a shady world of extortion schemes, and need to
make decisions about whether to pay third parties to "certify" your
domain to a blacklist. In the old days losing an email was considered
unacceptible; these days, there is so much junk that false positives are
expected and routine. Yeah, I've been doing this for a long time--more
than 20 years of dealing with email servers--but I don't really think
email in its traditional form will exist much longer. Heck, there are
even debian contributors whose personal email domains bounce emails from
other debian contributors. Who knows if they're even aware of that?
