Some eMail messages not getting to locations ??? Whats up !

[SS-Nutz]

Hi. OK some of my email messages aren't getting through. About 50% are going
through fine. I know because I have been contacting the destination now that
I know I have an issue.

I have checked my settings, made sure my antivirus email check has been
disabled & even called Comcast support. I never used to have this issue.
Comcast says it is an outlook issue (Of course they did, pass the buck). I
don't get any error messages and outlook says the emails were sent fine.

I have read some others having a similar issue but haven't read a solution
or fix. Any help would be greatly appreciated.

Create an account at another e-mail provider (not the one you use for
sending your e-mails). Send a test e-mail to the problematic recipient
along with adding yourself in the Bcc field. Check if you are getting
your test e-mail at your other account. This would prove if your e-mail
provider accepted your message and then sent it out okay. If so, the
problem is on the recipient's end that you can do nothing about (they'll
have to fix the problem at their end).

There are many possibilities why email messages do not reach their
destination. One of them could be spam filtering on the recipient's mail
server, i.e. filtering by IP range. Comcast IP addresses are often
found on blacklists, as a lot of spam originates from there.

Ask the recipient(s) if their ISP's mail servers employ IP address
blacklists.
