[Q] Problem: Only send email when connected to Wi-Fi

[bass3587]

I'm running the stock Android OS on my Captivate no changes at all. My problem is when I use the stock email client or K9 I can't send an email unless I use Wi-fi. Now if I log into my Gmail or Yahoo account using the web client I can send and receive email. I should also say that I can receive emails if I choose to manually check for new messages and sometimes it will receive messages throughout the day. It had me thinking I had some setting to check for new mail but I couldn't find it. Anyone ever had this problem and if they did how did they fix it.
