I tried the SPF Wizard, but I’m still having a problem getting everything to pass on mailtester. I get too many spf lookups as the error.
RE: your SPF record <br> <br>Change the <code>-all</code> to <code>~all</code>. You may also want to run through the <a href=“http://spfwizard.com/”>SPF Wizard</code>.
OK, this one seems resolved - the issue was in IPv6, <br>Just set inet_protocols=ipv4 in /etc/postfx/main.cf, restart postfix. <br> <br>Now emails are forwarded: <br>postfix/smtp[3819]: EFC4D1C11D5: to=dfd@asdfasdf.com, orig_to=ttt@sdfsdf.com, relay=aspmx.l.google.com[173.194.69.27]:25, delay=6.3, delays=0.3/0/5.2/0.73, dsn=2.0. <br>0, status=sent (250 2.0.0 OK 1384239619 cl1si1153461bkc.228 - gsmtp) <br> <br>status sent, but not appear come to gmail, but this is another story :)
triavi.com. 1800 IN TXT “v=spf1 ip4:37.139.30.113 -all” <br>telnet aspmx.l.google.com 25 works (it uses ipv4) <br>telnet to my host works as well. <br>I’m not trying to use it’s smtp,-it’s an email forward (via /etc/postfix/virtual) <br>
Has it worked before? Have you tried restarting your droplet? If you installed a firewall, did you open the necessary ports? Have you created an <a href=“https://www.digitalocean.com/community/articles/how-to-use-an-spf-record-to-prevent-spoofing-improve-e-mail-reliability”>SPF record</a>? <br> <br>Also, I don’t think Google allows unsecure connections (i.e. on Port 25). I think it requires TLS on the default port: 465. <i>See</i> <a href=“https://www.digitalocean.com/community/articles/how-to-use-google-s-smtp-server”>How To Use Google’s SMTP Server</a>.
