Flask, and using Flask-mail to send email through my smtp.office365.com server.
In my localhost it works fine but when I deployed it to AWS EC2, it simply does nothing, not even raising an error. Any ideas? I have already opened all traffic in the inbound rules as last idea but still nothing changes.
but the port im using is 587 tho
Outgoing SMTP traffic to foreign servers always uses 25. 587 is client-to-server connection for submission.
right, gotcha. Thank you very much, I will then request to remove that 25 Throttling. Thanks a lot
Lots of providers do this to prevent their IPs being marked as spam, it's a shame but a necessary measure
Cheers man, that saved me. you made ma day. i've been literally hours to fix this or at least to find where the problem was lol
