difference between phone and laptop emails

[#1]

Received the email about changes.  Laptop set up needed to have the relay.plus.net change made but has worked throughout.  One hour after receipt of the email about changes my phone stopped receiving emails.  I have checked the settings (I'm not techy so this was a result) and the settings are correct.  Still, it hasn't/won't update.  Last sync was just before 6pm last evening.
