well, lesseee
$ host 188.183.91.18
18.91.183.188.in-addr.arpa domain name pointer
0xbcb75b12.cpe.ge-1-1-0-1112.hcnqu2.customer.tele.dk.
$ host 0xbcb75b12.cpe.ge-1-1-0-1112.hcnqu2.customer.tele.dk.
Host 0xbcb75b12.cpe.ge-1-1-0-1112.hcnqu2.customer.tele.dk. not found:
3(NXDOMAIN)
so rdns is borked. chances are this is intentional...
compare this with the 2d french ISP situation:
$ host 82.239.111.7
7.111.239.82.in-addr.arpa domain name pointer
mon75-10-82-239-111-7.fbx.proxad.net.
$ host mon75-10-82-239-111-7.fbx.proxad.net
mon75-10-82-239-111-7.fbx.proxad.net has address 82.239.111.7
so rdns is correctly configured.
now all this is "generic" names. so compare with (which the said second
ISP allows you to configure using your web UI, for no fee):
$ host 82.239.111.75
75.111.239.82.in-addr.arpa domain name pointer ouzoud.netoyen.net.
$ host ouzoud.netoyen.net.
ouzoud.netoyen.net has address 82.239.111.75
anyway, back to tele.dk, I have
/^0x\d+\.cpe\..*\.customer\.tele\.dk$/
REJECT generic hostname. Please use your ISP relay or fix your
hostname.

since you are a customer, it would be good if you contact them to fix
their rdns (I wonder if it not intentional). and more importantly, I'd
like to know if they provide custom rdns freely or at least for a
reasonable price.

not sure. here in .fr, the major ISP is Orange, and you can only get a
custome rdns if you pay for (while it's free with the 2d ISP, which is
free.fr/proxad). but Orange block port 25 (well, not sure it's been
completed...).
