not only microsoft-related, a suggestion to those managing more than one server: use only one of them to send out the mail and use it as a relay for the others. from my experience this leads to better results, even if there are hacked accounts from time to time - the big providers seem to be OK with an IP sending some spam if it sends loads of "good" mail most of the time - but if a server only sends 10 mails a day it gets blacklisted much faster.
btw, does anyone know if the big providers take into account that some spam is only forwarded, not originating? we have many customers who want to forward their mail from someth...@myname.com to their gmail/hotmail/etc. mailboxes - which sometimes leads to problems if they receive many spam mails Andreas Brandon Long via mailop schrieb am 08.02.2017 um 21:48: > > > On Sun, Feb 5, 2017 at 2:44 AM, Klaus Ethgen <klaus+mai...@ethgen.de > <mailto:klaus+mai...@ethgen.de>> wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA512 > > Am Sa den 4.
