AOL blocks delivery from hughesnet
I read similiar topic but problem is not with the recipient filter. I have 5 aol folks on email list and they are all (temporarily?) blocked. Error code 554 RLY:B1 means AOL has a dynamic block based on a "complaint threshold" that they supposedly remove after 24hrs. This seems like a rolling block by AOL server and I've been able to send email to recipients after a few days. AOL seems to have a way to validate the senders server as trusted. I know that this is an AOL problem, but could you somehow git hughesnet off of their sh** list? I've spent way too much time trying to resolve this issue. Any help is appreciated. Peter
What may be happening is this:
Hughesnet has many users sharing the same IP address ... hundreds of users. If one of those users has an issue ... virus/malware or is just an outright spammer they may trigger a 'block' being set in place by AOL in this case, but instead of blocking by email address they block by IP address. That being the case, instead of blocking the one offender they instead block everyone sharing that Hughes IP.
In some cases the block may only be in effect for a set period of time, in other cases it is a persistant block that needs to be handled between the two parties .... Hughes and AOL in the instance.
