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.
