Hi

I have 1 domain and 2 aws ec2 instances. I have 2 subdomains, 'dev.mydomain.tld` and 'prod.mydomain.tld' one pointing to one instance and the second pointing to the other one.
My primary domain is configured to point to the IP of one of this instances. I have configured MX, and txt/spf records and also rdns for all of them. Both machines have a local mta, POstfix for sending emails to customers. One of them, `dev` sends emails fine. The other one 'prod' will send email in 'spam' although it's configured to send emails using `dev`.

Any thoughts?

Oh, forgot to tell, when sending email from console (mail -s "test" bleah@gmail.com < /dev/null ) I get the email fine, in INBOX. The trouble is when sending emails from Drupal. When drupal sends email, it gets into 'SPAM' dir.

Is your drupal site is also running on the same server? How is drupal sending the email? Well, one easy thing would be to compare the settings for both the servers, if something is missing in dev. A mail can go to the spam folder for many reasons, no ptr record/reverse dns record, no spf record, no fully qualified host name, massage content etc. Here are some hints:

Thanks mmheera

And to try to answer your questions now. I'm not sure how drupal is sending emails. I haven't configured drupal. it was there installed. I guess it calls '/usr/sbin/mail'. Also Redmine is installed there and sometimes the emails go to Inbox but sometimes they are going into 'spam'. This is really annoying. I have ptr records for both, and spf and fqdn. Dunno about the message content.
