I have been googling on this topic for over a solid hour now and can't seem to find an answer.
At my work, all employees get the following (good old) warning whilst firing up their Outlook clients:
security certificate does not match the name of the site
My colleagues told me not to worry about it, just ignore the warning, etc. I was wondering, could that, in any way, lead to your mail server's IP getting blacklisted by spam filters? (Namely backscatterer in this case.)
(For example, could it happen that you send out an email, some spam filter sees the mismatch in the certificate, suspects possible spamming activity, or some sort of security breach behind it, and blacklists the IP?)
