Outgoing Mail Server Smtp Login Error 535
What is authentication? When you use email in Desk.com, IMAP or SMTP is used to send or receive the email. Communication is opened between the Desk.com servers and your mail server, and Usernames and Passwords are used to authenticate the user. All IMAP servers require authentication, but some SMTP mail servers do not require authentication.
SMTP -> ERROR: Password not accepted from server: 535 Incorrect authentication data SMTP -> ERROR: RCPT not accepted from server: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. dev.camppage.com 550-(patchvalues.com) [220.127.116.11]:50958 is not permitted to relay
outgoing server: mail.mpronto.com, port 25 incoming server: mail.mpronto.com, port 110 username: [email protected] (i.e., you need to specifiy your domain as part of the user credentials.) My outgoing server (SMTP) requires authentication Use same settings as my incoming mail server no encryption for either incoming or outgoing server.
The only thing I was doing different from your instruction article is at the SMTP server address. Instead of using my MX record of "p*****p-com.mail.protection.outlook.com", I used "smtp.office365.com".However, I have since re-tried following your exact guide and used the MX record for SMTP server address.
Is there something wrong with the SMTP authentication at the moment??? keep getting 535 error, invalid userID or password. The ID and password hasn't changed, and I can log-on the web-mail.
We are experiencing the same issue. We can be sure that the Gmail server settings and code is correct, as our production server (on different infrastructure, same domain) works fine and is currently sending emails.
