Good. We have just ruled out dot 2 and 3.
Now please use your e-mail address from SFR and try sending e-mails again. Check your SFR mailbox as well.
Wait around 5 minutes after sending the e-mails. There may be delays because of traffic overload..
For now I do not receive any message. I checked on my online SFR mailbox and on my software “Thunderbird”
Then there is nothing I can do about it.
SFR blocks our mailing nodes.
You should contact them to unblock us, or create an e-mail with another provider, such as Yahoo or Google and use that one instead
