thanks for the help in advance !!!
where is the problem here?
why is the void setPublicIpDescriptor(const char *publicIpDescriptor = “mymailde”); part not taken?
Where does this need to be placed in the code?18:58:11.100 -> Connection: ESTABLISHED

Hi Matthias,
I check your server
reef@PORTATIREEF:/mnt/c/Users/renzo$ telnet smtp.ionos.de 25 Trying 213.165.67.97... Connected to smtp.ionos.de. Escape character is '^]'. 220 kundenserver.de (mreue010) Nemesis ESMTP Service ready EHLO 213.165.67.97 250-kundenserver.de Hello 213.165.67.97 [XX.X.XX.XX] 250-8BITMIME 250-AUTH LOGIN PLAIN 250-SIZE 140000000 250 STARTTLSand It implement a SASL Authentication, so I must change the library to support this type of login. I read something and probably we must send a single line with login and passwd.
I’m going to try to do a trial version, I write here when ready to test.

Hi Matthias,
try this version on GitHub branch postfixEMailServer
to activate new features you must add this lines
emailSend.setEHLOCommand(true); emailSend.setSASLLogin(true);give me a feedback.

Hi Renzo,
this time the log is much shorter, but the auth error is still there.
The positions with PWD etc. are exactly as in the original log, only here anonymized

Hi Renzo,
the problem is that it encrypts the user name and password together.
I think that only the password must be transmitted as base64, right? But how is the user then communicated to the server? Is there maybe a step missing?Bye Matthias

okay, I was too hasty.
Unfortunately the email is empty. It arrives at the recipient, but without content 🙁

Hi Matthias,
I’m moved :’) .
The last problem seems the antispam filter that block the content.
Subject: [SPAM?] Email Status TEST X-Spam-Flag: YES X-UI-Filterresults: junk:10;V03:K0:BwtejaETKmM=:nonYreUx2XTry to send simple text message, or better send message to another email provider (and check spam).
But I think now the flow It’s ok.
Bye Renzo
