I don't have any knowledge of Cyrus, so not using it. Can you please mention any link, tutorial, howto to achieve objective i am looking for ? I thought something like following i need to do on both exim instances correct me if i am wrong. I will create china users mailboxes on china exim instance and for US users i create mailboxes on US exim instance. But still not sure how to keep same domain name for china & US users because china pointing to mail1.example.comand US exim pointing to mail.example.com. So china users will use mail1.example.com in email client to send / receive while US users will use mail.example.com in email client to send / receive email. Please let me know how to keep same domain name @example.com The scenario i am looking will work as follows: First system look for localuser, let suppose someone from china sends an email to his colleague in china [email protected] sends to [email protected] it first check [email protected] exists locally and will deliever it within china to xyz mailbox by localdelievery transport. begin router localuser: driver = accept check_local_user # local_part_suffix = +* : -* # local_part_suffix_optional transport = local_delivery cannot_route_message = Unknown user And if [email protected] exists in US exim server than it executes router send_to_gateway and checks email sender address is @example.com and email is for @example.com than email will relay to US exim server where US exim server will handle that email locally. send_to_gateway: driver = manualroute condition = ${if eq {${lc:$sender_address_domain}} {example.com} {true} fail } domains = example.com transport = remote_smtp ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 route_list = * example.com host_find_failed = defer Finally if anyone from china from email [email protected] sends an email to external domain like hotmail,yahoo it will send via dnslookup from china. dnslookup: driver = dnslookup domains = ! +local_domains transport = remote_smtp ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 no_more begin transports remote_smtp: driver = smtp local_delivery: driver = appendfile file = /var/mail/$local_part delivery_date_add envelope_to_add return_path_add group = mail mode = 0660 Please let me know if you found any errors, flaws in it.I am looking forward for your suggestions.
