Dear Sir

I have an issue regarding receive and sending an email from my thunderbird account. So i just take a look for SMTP server port without editing any parameter, after that i try to login the thunderbird account using mail app on my Android. But i cant login on the android then my account on thunderbird PC is error. The error said:

Sending of Username did not succed. Mail server <my mail server> responded: Protocol Error. 14

Because of that error, i cant sending or receiveng email via thunderbird. Can anyone please give your advice to solve my issue?
