This is essentially a DNS issue. For email to get anywhere on the internet, the destination host (or at least it's domain) needs to be know in the public DNS. What is also needed to be provided by the DNS records is an MX (mail exchange) host specified for the destination domain. For example... $ nslookup -q=mx bflsoftware.com Server: localhost Address: 127.0.0.1 Non-authoritative answer: bflsoftware.com preference = 0, mail exchanger = sandesh.bflsoftware.com Authoritative answers can be found from: bflsoftware.com nameserver = STPB.SOFT.NET bflsoftware.com nameserver = TAURUS.SOFT.NET sandesh.bflsoftware.com internet address = 164.164.49.10 STPB.SOFT.NET internet address = 164.164.4.5 TAURUS.SOFT.NET internet address = 164.164.128.16 The mail exchange host for your domain is sandesh.blfsoftware.com. (Preference = 0 is probably a bad thing, btw. 5 or 10 would be more conventional). $ nslookup linux.bflsoftware.com Server: localhost Address: 127.0.0.1 *** localhost can't find linux.bflsoftware.com: Non-existent host/domain Your linux box does not have a DNS entry. If it did, then email would still be sent to sandesh - unless there was an MX record specifically for your linux box. If you use something like a mailertable/virtualuser with sendmail on sandesh, then you can get all your email to be forwarded on to your linux box directly with smtp from sandesh. If any of this is confusing, then go check out the BIND and sendmail FAQs. If it is _still_ confusing, then you are swimming out of your depth... :) Pushing email around to the all the places it is supposed to go is sometimes good fun... very pleasing when you get it working. Good luck.
