hi, i can receive but not send messages anymore. i've got three email accounts. the accounts from my internet provider (whose i 'm using its SMTP server) is working fine and i can receive message with this account. the other two accounts don't send.

this is the error: An error occurred while sending mail. The mail server replied: MAIL FROM: <______________> does not match authenticated user name. Please check your email address in your account settings and try again.

i checked all settings and they look ok. i found out that if i change the port from 587 with password to 25 without password i can send email. this can't be a solution as it's a not secure connection and moreover it doesn't always work.

how to solve this? thanks
