We will be doing some maintenance on Tsunami's mail service on Thursday, April 2, 2009 late evening (likely around 10 or 11pm EST).
The change should have no impact on anyone unless you are using SPF records in cPanel for your mail configuration. On Tsunami that appears to be 8 accounts. Edit: 5 accounts.
For those users they *may* see a few hours of sending issues only if their recipients require spf record validation. It's very likely this will be transparent but I will be emailing those customers directly to let them know. Even then, it will only impact sending for a few hours, not receiving.
Thanks
This has been completed. If you are on Tsunami and have any email issues, please let me know. Thanks!
