by looking at my mail server's logfiles, I can see that when Meteohub sends it's EHLO command, it's followed by "localhost", so: "EHLO localhost". This is not correct and should be the Source address configured under Push services.
Stating "localhost" as EHLO host makes the server mark the e-mails with a higher spam score per default.
Meteohub's SMTP EHLO command states "localhost"
