I am using Thunderbird ( currently 16.0.2) for a long time in Ubuntu . it works perfectly . But in two weeks , I got a notification: gmail account exceeded command or bandwidth limits , and I can not send email as well as receiving email using Thunderbird and iPhone.
I didn't use Mail client ( thunderbird and iphone) for 1 day after that. And Now , I can read email but can not sending email.
The message could not be sent because the connection to SMTP server smtp.googlemail.com timed out. Try again or contact your network administrator.
I try to telnet smtp.googlemail.com port 465 but no luck., port 587 is ok. I change the the SMTP server to port 587. But I still can not send email.
It show : connected to smtp.googlemail.com , but still show that window , and never send the email.
Any idea ? Thank you very much.
