Am having a real challenge getting certain mail from my bank
when using Mail.app and my iCloud.com ID.
I receive from these address with no problem:
info@bank.org
noreply@bank.org
notification@sendmail.bank.org
BUT I don’t get any from:
The only difference I see is the two periods in the domain.
I DO however get 2 period email when it is sent to my gmail.com ID
Any thoughts welcome
(I have NO mail rules in either the app, or iCloud.com)
That third successful address seems to also contain two periods in the domain. Maybe it’s something else?
Y’know I noticed that after I posted it, I’ll have to check my valid addresses again, but I think I might’ve fat fingered it and it was a dash
Subdomains (the bit between the @ and before the first period) are long established, especially in large organisations.
Have you searched the web for subdomains, email problems and iCloud?
It might not have anything to do with your setup, it’s possible that the domain email signing is incorrect for forms.bank.org MX records. You can use this tool: DKIM Check- DomainKeys Identified Mail (DKIM) Record Lookup - MxToolBox to check for your domain’s DKIM and DMARC DNS records. If they don’t have DMARC records for forms.bank.org that might be an issue.
That it works in Gmail and not in iCloud might point to differing levels of spam protection in each service.
