Fatal! Write Failure to /etc/valiases

Fatal! Write Failure: /etc/valiases/yourdomain.tld. Ignore any messages of success this can only result in failure!

First, verify that your domain exists (as a file) in /etc/valiases, and that it has “username:mail” permissions.

# touch /etc/valiases/yourdomain.tld # chown username:mail /etc/valiases/yourdomain.tld

DomainKeys and SPF Record Checking

tech — Sun, 11 Apr 2010 03:00:36 +0000

You probably know that you can configure DomainKeys and SPF records in cPanel >> Email Authentication (if you didn’t, there you go ). If you’d like to confirm that your TXT records are working properly, here are some resources for you:

SPF Record Check – via HTTP
PoliteMail’s SPF Check – outputs a brief breakdown of your records details – the IP addresses permitted in the record, the hostname, and the mailserver name. Then outputs the TXT record it queried.

MXToolBox’s SuperTool – Provides SPF checks, among other useful queries.

SPF Record Check – via email
This is pretty neat – you can send an email to spf-test@openspf.org from the domain you want to test, and it will reject the message, but in that rejection message, you’ll see the results of your test:

spf-test@openspf.org SMTP error from remote mail server after RCPT TO:: host mailout02.controlledmail.com [72.81.252.18]: 550 5.7.1 : Recipient address rejected: SPF Tests: Mail-From Result="pass": Mail From="test@cpaneladmins.com" HELO name="server.cpaneladmins.com" HELO Result="none" Remote IP="12.34.56.78"

Other Resources:
OpenSPF.org’s Wizard – If you want to configure SPF records manually, go here. Note that you won’t be able to edit the records via cPanel >> Email Authentication later on, though.
