I have Postfix running mail server for several small domains, all working
well.
since about 48 hours, several of my domains started getting bounced from
hotmail as per below
checked with mxtoolbox, mail server is:
Checking emu.sbt.net.au which resolves to 103.15.178.123 against 100 known
blacklists...
Listed 0 times with 3 timeouts
has hotmail changed or enforced something new in the last few days ?
is there something I should do on my Postfix ? dns ?
yesterday, I've added dns record as below, is that a must have ?
TXT sbt.net.au 60 min v=spf1 a mx ~all
