Problem sending email, email goes into Outbox

1

App version 6.603

Cannot send any emails. The smtp settings are verified as correct. Other PC based email apps work fine with same email provider and smtp settings. Please help.

The pertinent part of the debug output below:

SMTP <<< 235 2.7.0 Authentication successful
.
SMTP >>> MAIL FROM:<zxcvbn@sbcglobal.net> BODY=8BITMIME 
SMTP >>> RCPT TO:<qwerty@sbcglobal.net>
.
SmtpTransport$logger: Error parsing enhanced status code
SmtpTransport$logger: **com.fsck.k9.mail.transport.smtp-SmtpResponseParserException: Unexpected character: R (82)
.
.
.
SMTP <<< 550 Request failed; Mailbox unavailable
02-20 21:24:33.299 12061 13685 V SmtpTransport: SMTP <<< 503 5.5.0 Need MAIL before RCPT
02-20 21:24:33.300 12061 13685 D SmtpTransport: SMTP >>> QUIT

MAIL was sent before RCPT

New user can’t post full debug output that I have.

Welcome @bob.0001 :wave:

It looks like your outgoing server doesn’t like the MAIL FROM command. Please double check to make sure the correct email address was used with this command. You can change the email address in K-9 Mail under Settings → [Account] → Sending mail → Composition defaults → Your email address.

If it was the correct email address, please contact your email provider to ask why the error response 550 Request failed; Mailbox unavailable was returned. You can also let them know that this error response is missing an enhanced status code (see RFC 3463).
