Hi, I am trying to send messages from my website which would not end directly in the bin of webmails. Now except from Gmail who nicely accepts mails from my website as "spams" , the other webmails dont even show them. I am very new to server configuration and might be a bit confused in my explanations but i'll try to be as clear as possible. My server runs under debian 7.9 and I am hosted by 1&1. To try to understand why my mail is not accepted by servers, I made a test with mail-tester.com. Here are the results of the test: -Your Reverse DNS does not correspond with your sending domain. (here 22.214.171.124 is not my IP but just an example) Your IP 126.96.36.199 is associated to domain.fr But your message seems to be sent by s18927986.domain.fr You should modify your hostname to domain.fr IP: 188.8.131.52 HELO: s18927986.domain.fr rDNS: domain.fr (Here I have to add that I modified the DNS more than 72 hours ago) -You should add your SPF as a TXT record in your DNS - We have found an SPF on your server but it dident propagated yet. We found: v=spf1 a mx ip4:184.108.40.206 ~all domain.com: No applicable sender policy available So here are my configuration files: /etc/exim4/update-exim4.conf.conf Code: dc_eximconfig_configtype='internet' dc_other_hostnames='domain.fr' dc_local_interfaces='127.0.0.1 ; ::1' dc_readhost='' dc_relay_domains='domain.fr' dc_minimaldns='false' dc_relay_nets='' dc_smarthost='' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='' dc_mailname_in_oh='true' /etc/hosts Code: 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters # Auto-generated hostname. Please do not remove this comment. 220.127.116.11 domain.fr s18927986 /etc/hosts Code: s18927986.domain.fr Here are the MX recorded on 1&1 Code: MX s18927986.domain.fr MX mx00.1and1.fr MX mx01.1and1.fr And SPF and TXT Code: Name: domain.com Type: SPF Value: "v=spf1 a mx ip4:18.104.22.168 ~all" Name: mail._domainkey.domain.fr Type: TXT Value: "v=DKIM1; k=rsa; p=MI......" Would anyone see what is not right in all this? Thank your in advance for your help.
