On every application server a local MTA is running and listening on localhost port 25. You can use it to send mails.
The advantage of using the local MTA is that mails are queued if they can't get delivered directly.
SPF
To get better message delivery you should configure a SPF Record Show archive.org snapshot for all domains you use for sending mails.
If you already have a SPF record, please add include:_spf.makandra.de to it. If you are not having a SPF record, please ask your email provider how to set it up. If you are not sure about what to do, you can also write us an email to ops@makandra.de.
For example if you also use google apps with this domain you have to configure
v=spf1 include:_spf.makandra.de include:_spf.google.com -all
DKIM
All mails that are sent with the domain name of the application server are automatically signed with DKIM.
If you want to send mails with your domain name and want to have them with a DKIM signature you need to do the following things.
- Create the two records
mak1._domainkey.$DOMAIN CNAME mak1.dkim.makandra.cloud.
mak2._domainkey.$DOMAIN CNAME mak2.dkim.makandra.cloud.
- Inform us that you want to have DKIM enabled for the domain
$DOMAIN.
