Yes, we check SPF (Sender Policy Framework) DNS records before a message is accepted.
Messages that pass the SPF check, or messages that “soft fail” the SPF check (i.e. no SPF DNS record for the domain exists) will be delivered.
Messages that “hard fail” the SPF check (i.e. are sent from e-mail servers not specified in their SPF record) will be rejected before they can enter Rhombic Networks’ mail processing queue, reducing the amount of spam our users get.

Yes, we do offer phpMyAdmin. You will need both your MySQL username and password to login at:
https://my.rhombic.net/phpmyadmin
Please use our copy of phpMyAdmin rather than installing your own. Our copy of phpMyAdmin is maintained for security, and optimized for speed, with many of phpMyAdmin’s more complicated features enabled (e.g. linked tables, which allow PDF generation).

No, we do not impose any limitation on MySQL database size.
However, we do request that you do not store binary data, such as pictures and images, in your MySQL databases. Databases are meant to kept textual, relational data. High-performance databases like MySQL begin to lose their performance quickly with huge records, such as the ones containing binary data.
If you are storing a large amount of binary data in a database, Rhombic Networks’ reserves the right to call into effect our clause of excessive usage in our terms of service.
If you would like more information about why binary data in relational databases is bad, a good article to read is: Serving Images From A Database.

No, Rhombic Networks does not allow reseller hosting.
Reseller hosting is a detriment to the web hosting industry. To keep our quality of service at the top of the pack, we do not allow reselling of Rhombic Networks accounts, which are designed for the individual person, small groups, or business.

If you’re using Apple’s Mac OS X and Mail.app and try to check your e-mail via IMAP, you may intermittently get the error:
There is no root certificate for this server.and:
This certificate was signed by an unknown authoritywhich can be seen in this screenshot:
Our certificates are valid, signed SSL certificates, so this appears to be an obscure, hard-to-reproduce bug with OS X not being able to authenticate their validity. This can be fixed by installing the necessary SSL root certificates into your OS X installation. Download both these files to your desktop:
Once downloaded, you can install them into MacOS X by dragging the files to the Keychain application (located in /Library/Applications/Utilities).
How can I protect my passwords (MySQL, etc) stored on your servers?

You may need to store passwords within files on your Rhombic Network account, such as MySQL passwords, HTTP authentication passwords, etc.
All Rhombic Network clients have system users that are part of the group “users”. Because a web server process will either use the user “www-data” or your own system user to access files, you can use standard UNIX permissions to prevent access to sensitive files.
To protect a file secret.php, run the commands through SSH:
chgrp users secret.php
chmod 604 secret.phpDoing this will prevent other Rhombic Networks users from being able to snoop your passwords and private data, but still be viewable or usable by a web server.
