Added mailgun subdomain of the form the postman.domain-name.com
. The domain is purely for email. Created 5 DNS records of which they asked for verification. Domain confirmed and connected to the service.
Now, send him letter to your e-mail in Yandex.Mail.
If the "From" field is the address firstname.lastname@example.org
- a letter appears in the mailbox Yandex.
If the 'From' filled as email@example.com
the letter is not delivered, and the mailgun interface it is marked with the error:
5.2.2 Mailbox size limit exceeded 1578276298-gyMZMkM6XP-4vS4AhHG
Search for this message gives the page of Yandex, where they write that it is necessary to log in to the web mail interface to this bug fix. Okay, open your web mail interface, send a mail firstname.lastname@example.org and I see it in the Inbox. Then, without closing the browser tab with the mail interface, change in your application to the address on email@example.com the letter comes in the mailgun log error quoted above.
Why is this happening? I have no ideas at all...
If you ignore and leave firstname.lastname@example.org as the sender, then cidet MS Outlook emails to SPAM, because the main domain connected email from Google via G SuiteUpdate 1
: Tried sending through HTTP API and via SMTP. The result in both cases is the sameUpdate 2
: the Error POPs up only if the domain was created in the region U.S./North America. For domains from the region of Europe, this problem does not occur. That is, if not sanctions... haha ((
