Today I was sending bulk messages, with an FROM
address and an ReplyTo
address from my virtual server.
75% of the bounces where from my server by the following email
mailer-daemon@vwp*****.webpack.hosteurope.de
25% of the bounces where from strange emails like this:
postmaster@sodifrance.onmicrosoft.com
postmaster@explomin.local
postmaster@lego.com
I understand from the wiki article that
A bounce message or just "bounce" is an automated message from a mail system, informing the sender of a previous message that that message had not been delivered
but why are 75% from my own virtual server? I didn't send anything to an email address from my virtual server.
Also, all bounce mail were addressed to the message given in FORM
and they all ignored my ReplyTo
field. Shoulnd't bounce messages usually use the ReplyTo
field?

. If the bounces came from your server and "strange emails", you likely have a virus or malware sending them. Again, you can check the transactions in your mail server logs to have a better idea of what occurred. Scanning your server would be wise too. – dan♦ Sep 18 '18 at 8:13
