Something in your configuration rewrites the recipient address from the "orig_to" address to the "to" address. The MX host for the nexthop domain is then: uconn.mail.onmicrosoft.com. MX 10 uconn-mail-onmicrosoft-com.mail.protection.outlook.com. with addresses (subject to dynamic load-balancing): uconn-mail-onmicrosoft-com.mail.protection.outlook.com. 10 IN A 216.32.180.170 uconn-mail-onmicrosoft-com.mail.protection.outlook.com. 10 IN A 216.32.181.170 It seems your new server is blocked from connecting to these. That'd be some sort of networking issue, unrelated to Postfix. > virtual_alias_domains = > access.ced.uconn.edu, > appmail.uconn.edu, > eri.uconn.edu, > finearts.sfa.uconn.edu, > law.uconn.edu, > math.uconn.edu, > ropercenter.uconn.edu, > studentorgs.uconn.edu, > students.law.uconn.edu, > testexchange.uconn.edu, > uconn.edu > virtual_alias_maps = > hash:/etc/postfix/virtual, > mysql:/etc/postfix/files/mysql_pn.cf, > regexp:/etc/postfix/maps/googlegroups, > regexp:/etc/postfix/maps/subaddressing Given that "uconn.edu" is a virtual alias domain, the rewrite looks normal and intended. So tackle the networking issue. -- Viktor.
