Cant send email out

I've been having trouble these past few weeks sending email out from my phone using both Streamyx and Tmnet email settings. Gmail seems to be stuck halfway whilst sending also. Sometimes can get through, half the time, cannot. My email attachments too big or what. Certainly not Flickr's problem wor. Tiu, wtf is wrong. Want to update my blogs on the go also stressed. Damn sienzzz, man. Anyone having the same problem?
