Can Recv. Can't send

My email is from my internet provide4r, I have been using eM Client for awhile. Today it won’t allow me to send an email, keeps asking for my password. Which I have reentered a few, to no avail. The pop up box just keeps comimg up.

I can recv email fine ???

Send us your SMTP logs please: go to menu Tools->Settings->Logging and check “SMTP” under the problematic account. Then restart eM Client, try to simulate the issue and send us (with reference to this topic) the logs using the same logging settings window. Thank you.
