That's closer to a real cause. The server you're trying to send to is replying with something your server doesn't like. I'm guessing Exchange thinks the error is a temporary one, and thus queues the mail for retry later. The timeout message you're getting is Exchange saying, "I've tried several times now, and it still won't go through; I'm giving up". It might be useful to see a transcript of the SMTP session, but before you go to the trouble: > DomainB is shirevalleydesign.com It appears you have some lame delegations (that's the actual technical term) in your DNS zone. When a DNS resolver encounters a lame delegation, it usually fails the lookup (returns SERVFAIL). Any MX that gets that result will consider the domain non-existent and reject it. Good money says that's your problem. The GTLD SOA nameserver shows the following delegations for your domain: $ dig +noall +ans NS shirevalleydesign.com. @a.gtld-servers.net shirevalleydesign.com. 172800 IN NS dns3.ptd.net. shirevalleydesign.com. 172800 IN NS dns4.ptd.net. shirevalleydesign.com. 172800 IN NS ns3.zoneedit.com. shirevalleydesign.com. 172800 IN NS ns7.zoneedit.com. $ The two ZoneEdit servers respond with zone information, but the ptd.net servers respond with a referral back to the root. That means those servers believe they are not authoritative for the domain. (Hence "lame delegation"; you've delegated authority to servers which do not believe they are authoritative.) $ dig +noall +ans +auth ANY shirevalleydesign.com. @dns3.ptd.net com. 116724 IN NS i.gtld-servers.net. com. 116724 IN NS j.gtld-servers.net. com. 116724 IN NS k.gtld-servers.net. com. 116724 IN NS l.gtld-servers.net. com. 116724 IN NS m.gtld-servers.net. com. 116724 IN NS a.gtld-servers.net. com. 116724 IN NS b.gtld-servers.net. com. 116724 IN NS c.gtld-servers.net. com. 116724 IN NS d.gtld-servers.net. com. 116724 IN NS e.gtld-servers.net. com. 116724 IN NS f.gtld-servers.net. com. 116724 IN NS g.gtld-servers.net. com. 116724 IN NS h.gtld-servers.net. $ Fix your DNS and try again. Either configure the two ptd.net nameservers with zone information, or remove them as registered nameservers for your domain. -- Ben ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
