i have good DMARC , SPF and MX setting but get this error :
Reason: Mail server for yahoo.com is not contactable. Message has expired and has been returned to Sender.
and
Communications Error: Socket connection to mta7.am0.yahoodns.net failed (error 10060). The host was either not contactable or it rejected your connection. Socket Family = 2; Host=67.195.204.72; Port=25
So
i add (update) this SPF record in DNS setting ( TXT type ) and problem resolved
v=spf1 ip4:3.3.3.3 include:_spf.google.com include:_spf.mail.yahoo.com ~all
Please Replace 3.3.3.3 with Your server IP
Yahoo And Gmail accept my emails now
Thanks
