When I try to send an email from one of my gmail accounts with the Mail Module of Seamonkey, I have this error message :
" Alert
An error occured when sending email.The mail server answered : Requested action not taken : mailbox unavailable. Sender adress is not allowed.
Please check the email adress in the settings of the account is correct and try again."

The mail I tried to send appears in the Sent folder in the gmail / sender account. It doesn't appear in the incoming mails of the email account to which they were sent.

The setup for both my gmail accounts are : STARTTLS 587.

I don't know (yet) where the problem comes from : is that something in my gmail accounts or in Seamonkey?
With other email clients, I can send emails with these gmail accounts.

Hoping someone can help,

Do you have the full Gmail address entered as the user name in the SMTP settings for the problem account?
