the reverse record is ok.
I guess I need to create a dkim...but as I said before I'm not sure what I've to put in @mynetworks once that I don't know the IP of the clients...
Hi esmiz, thanks for your reply.
I'm checking on internet your suggestion... hoping that also Falko will confirm it...
Another thing: setting up the SPT as this website
said, I can read:
Paste this into your zone file:
domain.com. IN TXT "v=spf1 a mx ~all"
When a mail server sends a bounce message, it uses a null MAIL FROM: <>, and a HELO address that's supposed to be its own name. SPF will still operate, but in "degraded mode" by using the HELO domain name instead. Because this wizard can't tell which name your mail server uses in its HELO command, it lists all possible names, so there may be multiple lines shown below. If you know which hostname your mail server uses in its HELO command, you should pick out the appropriate entries and ignore the rest.
So this should also appear in DNS. You may or may not be in charge of the DNS for these entries; if you are, add them.
mail.domain.com. IN TXT "v=spf1 a -all"
server. IN TXT "v=spf1 a -all"
Having a look into the mail.log, I can see that, even if I have different domains in the server, the emails going out from domain1, domain2, domain3, etc, have an HELO like: mail.domain.com
I was expecting to have an HELO related with the domain of the sender... is it normal?
