I've moved all my sites from 1and1 to Linode, repointed the name servers, and I am very happy with the performance increase.

I've left my domain names on 1and1 and would like to continue to use their email servers. I've followed the instructions on
http://www.linode.com/wiki/index.php/Ge ... g_up_email
Only I've replaced the GoDaddy mail servers from the example with 1and1's using:

mx00.1and1.com priority 0
mx01.1and1.com priority 5

All mail I send to my old email addresses are now bouncing back with a "550 550 must be authenticated" error. I've waited a few hours and this is still happening. Would it take longer to fix itself?
Am I doing this correctly or have I missed a step somewhere?

Thanks in advance

That page hasn't been updated since 2009 you should check out the linode library, http://library.linode.com/email which contains official linode documentation and is kept up to date. Have a go at following whichever guide is relevant to your distribution and if you have problems post again (include your email server configuration file any any errors)

Hi thank you for the reply.

I did check out the Linode Library first, and the instructions there are geared towards setting up your own email server which is why I kept searching and found the wiki. The Google Apps instructions seems to be the closest to what I am trying to do and the directions seem to be the same: create the MX records.

Maybe I just haven't waited long enough?

This is what was wrong. I had everything set right, but was impatient. Emails are now working correctly. Thanks for the help anyway!
