I have two email addresses on a domain which forward to other accounts. One is going to a gmail account and is working fine. The other is forwarding to firstname.lastname@example.org, and it has not been working.
I sent three test emails to the forward-only address going to rr.com. Three days later, I got the following returned message on each:
[quote]This is the mail system at host harlem.dreamhost.com.
email@example.com: delivery temporarily suspended: host
cdptpa-pub-iedge-vip.email.rr.com[220.127.116.11] refused to talk to me: 421
4.7.1 - Connection refused - <18.104.22.168> - Too many concurrent
connections ( <2> ) from source IP[/quote]
Is this a problem with rr.com, or do they just not like Dreamhost?
