>Can confirm, my server is also not accepted by google for years now when mailing someone with a business account. Hey, I remember you were one of the replies[1] in my previous thread that said I was exaggerating the "send emails" issue. Maybe your difficulty with Gmail's mystery filtering algorithm will warn others that depending on personal email servers for reliable outgoing email is a non-trivial endeavor. Perhap…
Good memory! A few things: - My comment in this thread was mainly about gmail for businesses, hence the contrast between "I'm not going to fix their problems and just tell the recipient their setup is broken" and the previous "it's doable". Other mail providers are usually no problem at all, and personal Google accounts are also better. - For email to personal gmail accounts it seemed to be enough to send a few mails…
You misunderstand the point I'm trying to emphasize. I'm not trying to dissuade you from running your own email. There are real benefits to controlling your own email server and it's great you've configured something that works for you.
I'm saying I disagree with how some proponents communicate the drawbacks. They discount (or are blissfully unaware of) the real difficulties of running a personal email server for critical outgoing emails.
In the previous thread and this one, there are several of us with decades of email admin experience saying it is tricky to debug "sender reputation" while the opposing side insists Gmail/MSOutlook spamholes are easy to fix and not a big deal. Therefore, one of the sides misunderstands the realities. With these conflicting accounts, readers contemplating running their own email server will have to decide who is more accurately reporting the state of the email ecosystem for personal servers.
The author (Tomaž Šolc) of the article discussed in this thread had ~15 years experience administering his own email servers and tried to do all the "correct" things as an upstanding citizen of the email ecosystem and yet his emails still suddenly got rejected by Gmail. Readers will have to conclude if he got bit by forces out of his control -- or -- he's incompetent and doesn't know what he's doing. (From my point of view, the author wasn't incompetent and his frustrations with Gmail's filter is a common reality. Maybe this time, he can update DMARC to fix Gmail rejections... for now. But eventually, a new Google AI spam algorithm will mysteriously reject his server's emails again.)
