smtp-auth

问题 I am not able to connect to smtp port no 465, which uses SSL authentication. Earlier it used to work in default port 25, but have changed the setting to point to 465 for outbound emails for all outgoing emails. This works perfectly fine when i use outlook but shows that it cannot connect to port 465. Below is the error. javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.MessagingException: Could not connect to SMTP host: smtp.bizmail.yahoo.com, port: 465 at javax

问题 I'm trying to send an email from a spring boot application with spring mail (1.5.8.RELEASE) JavaMailSender sending through gmail SMTP is fine. however sending email through my domain registrar's amtp (registrar name- 1and1, in case someone already worked this out) is not working.

问题 I have been trying to implement email functionality in a legacy app using the Legacy Mail API to add OAuth support after getting a token through the Device Code Flow starting with the Microsoft Sample Project. Along that route I have added SMTP.Send and many other API permissions to find the missing piece. (Including { "User.Read", "User.ReadBasic.All", "SMTP.Send", "offline_access", "Mail.Send" } in fear of missing one) I have been testing with the MailKit library to build a proof of concept

问题 I want to send an email by use of Python 3. I cannot yet make sense of the examples that I have seen.

问题 Up until yesterday I had no issue sending emails with python and now for some reason I am getting the following error.

问题 I'm using SMTPClient for sending emails to a SMTP server. But with Send method I can specify any false sender name or email. How can I prevent this? 回答1: It's the job of your mail server to decide on what it accepts as a sender email address - that's just a matter of policy.

In fact, introducing
