Thank you in advance.

It seems your question was already answered: You decide who is designated as permitted sender for your domain. What else do you want to know? Did you read what Google has been so kind to document on their support pages? Did you follow some other documentation after looking up the referenced keyword *SPF*?

Your SPF policy denotes who are allowed to send email on behalf of your domain. It currently looks like:

 tatoocdc.com.      14400   IN  TXT "v=spf1 +a +mx +a:tatoocdc.com -all"

The server that was attempting to send e-mail, with IP-address 83.235.69.32, is not included in that list in any way. Therefor gmail refused to accept the message. Exactly how your SPF record is configured.

If 83.235.69.32, with a hostname of smtp-out32.otenet.gr. should be allowed to send e-mail for your domain, then the SPF record should be amended to include that host.

Set for example "v=spf1 +a +mx +a:tatoocdc.com +ip4:83.235.69.32 -all"

Hello mr diya and thank you for your prompt reply. I set "v=spf1 +a +mx +a:tatoocdc.com +ip4:83.235.69.32 -all" as my SPF Record. Nothing change.

Two possibilities, DNS records get cached and it might take up to your TTL of 14400 seconds before the cache with the old record expires; and/or your mail providers load balances outgoing SMTP traffic and the second message passed through a diferent server, with a different IP

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
