Thank you for replying and checking out my setup. It’s the first time I’ve set up email forwarding like that, so I’m not at all certain about what I’m doing, so I really appreciate your feedback! It definitely gave me some confidence.
I think I might’ve jump the shark when I said that messages were not delivered. I’ve done it at night maybe 30mins after I’ve set everything up, and now I think that I was probably getting errors simply because I didn’t give services enough time to reconfigure everything. I guess? Not sure.
The next day I’ve tried to send test emails from my, let’s call it gmail account 1, to the “test” email that redirects those test emails to gmail account 2. It worked, and now everything seems to work correctly.
I panicked slightly because when I checked my setup via MX record checker it did display that some IPs are on the block-list. My first guess was my country (BLR), because I’ve gotten on some occasion even prompts in Google search to solve captcha to prove I’m not a bot.
But then I checked more and noticed it said IPs belong to NameSilo.
Hence I tried to contact NameSilo, they’ve told me the issue is on the Server provider side (Infinityfree in this case, presumably), and then I posted this thread here.
I also saw in that MX lookup that it said its NameSilo IPs which are being blocked on one occasion with that UCEPROTECTL3 filter, so I’m still unsure if it’s just unqualified support staff of NameSilo who didn’t recognize what’s the problem, or is the problem actually with Infinity IPs.
I personally, at this moment, don’t seem to have any problems and everything works fine, but it still nags me slightly that one IP filter seemingly can block some emails.
I guess I’d simply want to understand better what EXACTLY is happening behind the scenes and where to search for answers in case something goes wrong. Like, what’s the exact routing of emails as they arrive into my mailbox. If you could describe this to me, I’d be really grateful.
Say Person 1 sends me an email to [email protected]. What happens next with the setup I’ve got now.
Does this email go directly to NameSilo first? Or does server first checks Infinity, sees my redirects, then goes to NS, then NS handles redirect to Gmail? And at each point does that “spam list” see each IP owners correctly, or does some of these redirects kinda “mask” true owner of them. I don’t fully get this part.
Basically, I just want to understand how and at which point that IP ends up (or potentially can end up) in that spam filter.
Sorry for so many words.
Best regards, Stan
