Can two server blocks in mail module listen the same port

Server NGINX
1

When I config nginx like this, it reports: “starting nginx…2010/10/12
11:44:04 [emerg] 14955#0: duplicate “143” address
and port pair in /opt/nginx/nginx.conf.mail.imap:19”
Is there something I did wrong or nginx doesn’t support this?

IMAP proxy configuration

server
{
server_name test.com;
listen 143;
protocol imap;
proxy on;
sasl_service_name “imap”;
starttls only;
ssl_certificate /opt/certs/test.com.crt;
ssl_certificate_key /opt/certs/test.com.key;
}

server
{
server_name foo.com;
listen 143;
protocol imap;
proxy on;
sasl_service_name “imap”;
starttls only;
ssl_certificate /opt/certs/foo.com.crt;
ssl_certificate_key /opt/certs/foo.com.key;
}

server
{
#server_name default;
listen 143;
protocol imap;
proxy on;
sasl_service_name “imap”;
starttls only;
ssl_certificate /opt/certs/nginx.crt;
ssl_certificate_key /opt/certs/nginx.key;
}

I dont think the protocol allows for virtualhosts so I would say it’s
not possible
