First of all, I hope this is the right place to ask my question (otherwise feel free to tell me, where it would be more appropriate). I'm trying to leave Gmail due to privacy-concerning issues, and to switch to Gandi.net.Hence, I created my address and happily tried to send my first e-mail a month ago, unfortunately all my e-mails sent to Gmail addresses are marked as spams. I tried to follow all the recommendations made by Gmail (SPF, DKIM, DMARC) but without success. My email address is XXX[at]bouton[dot]eu[dot]com (of course XXX has to be replaced). Here is my DNS configuration (the help-centre of Gandi confirmed it was correct) :
@ 86400 IN SOA ns1.gandi.net. hostmaster.gandi.net. 1684161018 10800 3600 604800 10800@ 10800 IN A 217.70.184.38@ 10800 IN MX 10 spool.mail.gandi.net.@ 10800 IN MX 50 fb.mail.gandi.net.@ 10800 IN TXT "v=spf1 include:_mailcust.gandi.net ?all"_dmarc 10800 IN TXT "v=DMARC1; p=none; rua=mailto:XXX@bouton.eu.com"_imap._tcp 10800 IN SRV 0 0 0 ._imaps._tcp 10800 IN SRV 0 1 993 mail.gandi.net._pop3._tcp 10800 IN SRV 0 0 0 ._pop3s._tcp 10800 IN SRV 10 1 995 mail.gandi.net._submission._tcp 10800 IN SRV 0 1 465 mail.gandi.net.gm1._domainkey 1200 IN CNAME gm1.gandimail.net.gm2._domainkey 1200 IN CNAME gm2.gandimail.net.gm3._domainkey 1200 IN CNAME gm3.gandimail.net.webmail 10800 IN CNAME webmail.gandi.net.www 10800 IN CNAME webredir.vip.gandi.net.After my first mail sent to a gmail address I received this answer:

My technical competences are quite low, and I'm quite helpless, I have no idea, what I could try to finally be able to leave Gmail for another provider. Thanks in advance for your help !
