A part of the subdomains are managed by us, others subdomains by an
other entity.
So we can't configure a generic target for all subdomains as each
entity has its own target for SRV entries.

I have a question about configuration simplification for SRV
configuration (maybe it can be applyed for other entries).
We manage multiple subdomain of a main one (server1.example.com,
server2.example.com,...).
For A and MX entries, we use a general domain definitions with
wildcard but is there a way to do so for SRV without having to define
all subdomains (we have several dizains of it) ?
We have to define some SRV entries with the same target like :
_imap._tcp.server1.example.com IN SRV main.exemple.com
_imap._tcp.server2.example.com IN SRV main.exemple.com
Since a record is needed for each host, I think I would use something
like this:
imap._tcp.server1.example.com. IN SRV main.example.com.
imap._tcp.server2.example.com. IN CNAME
imap._tcp.server1.example.com.
...
imap._tcp.servern.example.com. IN CNAME
imap._tcp.server1.example.com.
The advantage here is that, if ever the target of the SRV record had to
be changed, only one record would have to be updated.
