This is just wierd.
I have an asp page set up that send out email through a smtp server. All of a sudden, it stopped working.
Testing has revealed this.
I have 3 accounts I've tested with.
and a network solutions hosted account.
We've determined that if I send a message that contains stuff like
Applicant Email: email@example.com
The message fails to be delivered. But
If I strip out the email address, it gets delivered.
I've used the smtp servers at rr.com, network solutions, and another 3rd part and in all cases, the message didn't go through and get delivered.
Is it possible they are all using the same blacklist, possible, but highly unlikely?
