Is there any way to get this to work? My DKIM signature works perfectly if I use the NS for my droplet and let me droplet handle the DNS instead of DO.
I'm struggling to prevent my emails from vanishing or ending up in the email spam folder, and it looks like it is my DKIM record that is not identified correctly, so is there anyone who knows how to set up the DNS records correctly for this? I followed this tutorial https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy. I'm using an Ubuntu 16.04 droplet with WordPress and Postfix, and all email is hosted at Office 365, except a few emails which are posted via a web form on the website, and that's where this issue comes into the picture. This is my authentication report: ``` ========================================================== Summary of Results ========================================================== SPF check: softfail DomainKeys check: neutral DKIM check: neutral SpamAssassin check: ham ``` This is my SPF record: ``` TXT example.com v=spf1 +a +ip4:1.1.1.1 ~all 3600 ``` This is my DKIM record: ``` TXT mail._domainkey.example.com "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC5N3lnvvrYgPCRSoqn+awTpE+iGYcKBPpo8HHbcFfCIIV10Hwo4PhCoGZSaKVHOjDm4yefKXhQjM7iKzEPuBatE7O47hAx1CJpNuIdLxhILSbEmbMxJrJAG0HZVn8z6EAoOHZNaPHmK2h4UUrjOG8zA5BHfzJf7tGwI+K619fFUwIDAQAB" 3600 ``` In my mail tester feedback I got the following result: ``` [SPF] Your server 1.1.1.1 is authorized to use www-data@example.com ``` ``` [Sender ID] Your server 1.1.1.1 is authorized to use inquiry@example.com ``` ``` Your message is not signed with DKIM ``` ``` You do not have a DMARC record ``` ``` Your server 1.1.1.1 is successfully associated with example.com ``` Please note that it's only emails from a web form on the website that ends up in a spam folder, and all emails sent via the website uses Postfix and a PHP mail() function. I'm not sure I can set a MX record, because last time I tried the Office 365 stop working, so any other advice on how to correct this is appreciated.
Please provide step by step instructions for setting up dns records for an email server. The tutorial says create a mx record, but not where or how to create it. Other tutorials give conflicting information. Such as "create a mx record at your registrar", the tutorial on dns says to point the mx record at the gmail servers, but I want to host my own email. I tried the modoboa setup that someone else suggested, but it was awful. Horrible software. I just want to send and receive emails and be able to use webmail. (because console email is not useful for attachments) I need for my website users to be able to have their own account too, and I'm not going to have them using a console.
I've tried everything I can think of to get DKIM working with Exim4 on my Ubuntu 16.04 server, but emails sent from my server are still not signed with DKIM! I am using Exim4, unsplit configuration. I generated private and public keys using these commands in /etc/exim4/dkim: ``` sudo openssl genrsa -out dkim.key 1024 sudo openssl rsa -in dkim.key -pubout > dkim.pub ``` I edited the following lines in /etc/exim4/exim4.conf.template: ``` .ifdef DKIM_DOMAIN dkim_domain = ${lc:${domain:$h_from}} .endif .ifdef DKIM_SELECTOR dkim_selector = mail .endif .ifdef DKIM_PRIVATE_KEY dkim_private_key = /etc/exim4/dkim/dkim.key .endif .ifdef DKIM_CANON dkim_canon = relaxed .endif ``` Then ran these commands: ``` sudo update-exim4.conf sudo service exim4 restart ``` Added this TXT record to my DNS records (using the public key): ``` TXT mail._domainkey "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCvnoSm2o5X9JoCKfYlhkRv5mj4yRscjlv5JmNj1PfBeZGp57XgriRCcA4S5/egrPI2VfKzoCwRsGp4uCD/UJ7+6DgCVNseSlD+n6n4mRANWWlfY7LvHfp8sAR80aurwNyx7/PHGg+ZukHcllvYCtZtg4jtZTrl8w1yiKXyJ3G3fQIDAQAB" ``` Sent an email from my server to my Gmail address, and it went straight to spam. I click "Show original" and DKIM is not mentioned anywhere in the email headers. Please tell me what I'm doing wrong! Thanks!
Hi, I am having problems with my VPS trying to set up Postfix as send-only SMTP server using this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-16-04 Everything has been done the same way as they say in the tutorial and I've followed both of these tutorials as well: * https://www.digitalocean.com/community/tutorials/how-to-use-an-spf-record-to-prevent-spoofing-improve-e-mail-reliability * https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy My Zone file has the following information: ``` $ORIGIN my.example.com. $TTL 1800 my.example.com.

I'm hoping this can be resolved without exposing it.* My mail.txt file inside `/etc/opendkim/keys/my.example.com` looks like this (which was generated during the tutorial for DKIM): ``` mail._domainkey IN TXT ( "v=DKIM1; k=rsa; " "p=MIGfMA0GCFqGSIb3DQEBAQUAA4GNADCBiQKBgQCZW8z/5Pvx6xhd2zEPAZNul02xDkb6xEOK1bgmDDypeZ18oOIOZk39WHU4tBoHyJm08e0ddfNtsmWSPyedjnIraOL+cG4lZgr0mAJmK/A1K2i+enoVQFiLitxieEeavtahTrJau5rr5BGqZFwAfwtdbSJOk4DrgexamwBnuaZL0wIGAQAB" ) ; ----- DKIM key mail for my.example.com ``` Using different DKIM checkers, I get information such as: ``` DNS query failed for 'mail._domainkey.my.example.com':NXDOMAIN A public-key (p=) is required ``` ``` DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=my.example.com; s=mail; t=1516097701; bh=WBgqksrfs7F0OzQkyE7LiZPHyfFFhl7N4CNav2f5YVw=; h=Date:To:Subject:From:From; b=nlLoX/6Me+yXljyGp2YDsojBYLEq7dgCt1PHcsvD2A5fh76pbWoJsM9kkm6ytn16z M/re5tI5UQzHOVu7oM7cB11zPHkhFl1efvV5mr+FfedglmFHtew/FsvFwjf/P/3Kld /h/rs26aPmOsFduTtlwUja532pmiyXInGiUsFzzM= Signed-by: admin@my.example.com Expected-Body-Hash: WBhgpZjQs7F2OzQkyE7LiZPHyflshl7N4CNav2f5VVw= DKIM-Result: permerror (no key) ``` Please note (as title says) that I have had these DNS settings up and running for a week now and the error persists.
