Thank you for your interest.
| We're working with a number of virtual domains

| urz.uni-magdeburg.de compute centre
| mathematik.uni-magdeburg.de mathematics
| ...
| (in the DNS there are MX records that control smtp transfer
| to that domains to our mailrelay servers (exim MTA)
the records for the virtual domains should describe the
outbound mailrelays.
|
| There are also a number of smtp servers that send/receive
| emails to/from that mailrelay servers.
|
| If there are following servers
|
| server1.urz.uni-magdeburg.de
| server2.et.uni-magdeburg.de
| server3.math.uni-magdeburg.de
|
| that can send emails with the domain part urz.uni-magdeburg.de
| ...
|
the records for the servers themselves should just be
"v=spf1 a -all"
the domain urz.uni-magdeburg.de should have a record
"v=spf1 a:server1.urz.%{d2} a:server2.et.%{d2} a:server3.math.%{d2} -all"
The spf-help mailing list will be able to advise you further.
