Hello
have a small site based on CMS script with a small database of subscribers (~900)
3-4 months ago change my hosting and after this never send any newsletter to my subscribers.
few days ago, try to send newsletter and got ~800 emails back [Mail delivery failed: returning message to sender] with such text
Code:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its

user email, server ip and server name is changed to [myemail@myserver.com, noreply@myserver.com, myserver.com etc]
as i said, i send ~900, and got ~800 back.
server ip isn't blacklisted
at first, i thought, that may be durign this 3-4 months all our subscribers close their emails, or something like this [:-)]
but few days ago i got mail abuse from one of my potential subscribers (@hisdomain.co.uk), who try to subscribe to our newsletter and don't get authorization email (with url). btw, i got bounced email back [Mail delivery failed: returning message to sender - The following address(es) failed:] . i contact this guy, with this "failed" email - everything is fine with his email.
so , seems that problem is on my side.
what do u think? what can be the reason of this.
thank you
