[Dovecot] multiple ip and ssl

[Lampa]

Hello,

is possible in some way use on each ip address different certificate
(for imap, for pop3). There are options like (but that is not enough
for me):

protocol imap {
 listen = *:10143
 ssl_listen = *:10943
 ..
}
protocol pop3 {
 listen = *:10100
  ..
}

I have server for 4 domains (each has own ip address), so i need bind
one ip address to one domain to one certificate(each certificate
contains name of domain):

domain1.tld (x.x.x.100) -> certificate domain1.tld.pem
domain2.tld (x.x.x.101) -> certificate domain2.tld.pem
domain3.tld (x.x.x.102) -> certificate domain3.tld.pem
domain4.tld (x.x.x.103) -> certificate domain4.tld.pem



Or i must run different instances of dovecot ? (using other config) ?

Thank you for advices.
