i am trying to send email via my app, and although it was working previously (i had to fiddle with the authentication to get it to work correctly) but it was working fine… today, i tested it, and i am getting this: Net::SMTPFatalError (550-Verification failed for [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) 550-(result of an earlier callout reused). 550 Sender verify failed ): anyone have any ideas? thanks! ---

Are you using ActionMailer or did you write something yourself? c.

Could you post the email configuration you put in your environment.rb file. ---

I’m no email guru, but it looks like they might be doing some kind of verification on the recipient end of this email transaction, like maybe trying to make sure your email address domain is valid before accepting a transaction. If you’d care to post your (sanitized) ActionMailer config from your config/environments/development.rb or production.rb file and also the code you’re using to send the message, we can maybe give you some more guidance. c.
