When you are using a BladeVPS at TransIP you can always use our mail service free of charge, also referred to as 'Carefree Mailing'. With this service you will always have the possibility to use our mail services after a one-time configuration of Exim on your BladeVPS. When using the mail service you will no longer have to worry about mails being delivered in the spamfolder due to incorrect reverse DNS or SPF-records, or because a blacklist is blocking mails from your IP-address.
To successfully set this up you will need to perform some configuration changes on your VPS to make sure your VPS and domains are properly authenticated for the use of our platform.Which information do I need to start using this?
- Your username and password. These will be visible during the configuration within our control panel, but you can always look these up via 'Manage Your Mail Service' > 'Username & Password'.
- The SPF-record (TXT) that is needed to allow our mailservers to send mail for your domain(s). If you have already set-up a SPF-record for a domain, adding "include:_spf.transip.email" to your current record is enough. If you don't have any SPF-record set up yet, you can add "@ 5Min TXT "v=spf1 include:_spf.transip.email ~all" to the DNS of the nameservers you are using. Should you have missed this record during the initial configuration, you can always view this in the control panel via 'Manage domain names' > 'My desired domain name is not listed' > 'Continue'.
- The TXT-record in which your authentication hash can be found. This will need to be added to the DNS-records of every domain you want to use for mailing. Should you have missed this record during the initial configuration, you can always view this in the control panel via 'Manage domain names' > 'My desired domain name is not listed' > 'Continue'.
- The DKIM-records which serve as an additional layer of verification for sending mail via our mail platform. DKIM-record can be seen as a sort of key where the public part (in the DNS-record) has to mach the private record that the mail server sends itself. Should you have missed this record during the initial configuration, you can always view this in the control panel via 'Manage domain names' > 'My desired domain name is not listed' > 'Continue'.
How do I configure Exim on my BladeVPS for use of the mail service?
The configurator in the control panel will walk through all the necessary steps via the console, but should you want to use SSH you can follow the steps listed below:
- Log in onto your BladeVPS via the console or via SSH and make sure you are running as 'root' or use the 'sudo' command to perform these steps.
- Execute the 'Debian'-config file 'dpkg-reconfigure exim4-config' if you are running Debian or Ubuntu.
- Select the following options:
Select: mail sent by smarthost; no local mail Enter the VPS's hostname (usually pre-filled) Enter the local IP's where you want exim to listen on for incoming mail (usually pre-filled) Enter 'other destinations' for which mail is accepted Enter the local domain you want to use to send mail from Enter the mailclusters hostname: vps.transip.email::587 - Please notice the double :: Keep number of DNS-queries minimal (Yes or No) - personal choice Split config in smaller files (Yes or No) - personal choice
- Use nano (or vim) /etc/exim4/passwd.client and add:
vps.transip.email:USERNAME@vps.transip.email:PASSWORDThe username and the password can be found in the control panel under ' Manage mailcluster' > 'Username & Password'.
- Restart Exim (/etc/init.d/exim4 restart)
- You can (quickly) test if it works by sending a test mail via 'sendmail':
sendmail -v YOUR@EMAIL.COM (Enter) [mail input]
