How do I stop Outlook/Office365 from changing a header?
I am using the Python library smtplib to send Email messages with Office365 as the SMTP server. Everything was fine until a few days ago when my From: header seemed to not be processed. The Python code I am using:
import smtplib
from email.mime.text import MIMEText
def login():
server = smtplib.SMTP(mail.mail_server, mail.mail_port)
server.starttls()
server.login(mail.mail_username, mail.mail_password)
return server
def send(subject, body):
msg = MIMEText(body)
msg["From"] = mail.mail_from
msg["To"] = ", ".join(mail.mail_to)
msg["Subject"] = subject
server = login()
server.sendmail(mail.mail_username, mail.mail_to, msg.as_string())
server.quit()
send("test", "test")
What is strange is that if I log onto Outlook or OWA, I can see my header if I view the sent message details. I sent a test header of From: xxxx <info@...>
However on the recipients inbox message, the header is simply the Office365 User's name and the info address as shown above (From: Name <info@...>). The xxxx custom header is gone.
What can be causing my header to be dropped?

Exchange is hostile and buggy. There is nothing you can do except switch providers.

While it may not be an ideal solution, I ended up setting up a new email account with the name I wanted and used that, instead of trying to force the From: header.
