Nearly all mail providers require a login. That is often username/password but it can be things like username/auth-key. So your mail sender will require the ability to do SMTP-Auth. After that most providers limit the email sent to be from the email address you used to login. I recently moved about 20 email accounts to various providers and that was all I needed to do to make sure I could send mail. All the work I did was using Postfix but I am sure you could get the same result with any other mainstream mail package. On 2/4/21 10:20 AM, William Park via talk wrote:
Hi all,
pop.mail.yahoo.ca was rejecting my login while back, but I was able to generate "password" at Yahoo site, and got Fetchmail working again. Now, smtp.mail.yahoo.ca, which I've been using as my outgoing server (SMART_HOST in Sendmail speak), is also rejecting my connection:
----- The following addresses had permanent fatal errors ----- <talk@gtalug.org> (reason: 554 Email rejected)
----- Transcript of session follows ----- ... while talking to smtp.mail.yahoo.ca:
MAIL From:<opengeometry@yahoo.ca> SIZE=865 AUTH=<> <<< 554 Email rejected 554 5.0.0 Service unavailable
The solution that worked for Fetchmail is not working for Sendmail. I guess, it's time for upgrade to Postfix. But, I suspect, I'll have the same problem.
So, bigger question for you guys...
- How do you send out email? via Postfix/Sendmail? Or, via Thunderbird? - How do you read your emails? via Fetchmail/Mutt? Or, via Thunderbird?
