  Description

This is my mailer-specific config:
[mailer]
ENABLED = true
SEND_BUFFER_LEN = 100
SUBJECT = %(APP_NAME)s
HOST = mail.xxx.de:25
DISABLE_HELO = false
HELO_HOSTNAME =
SKIP_VERIFY = false
USE_CERTIFICATE = false
CERT_FILE = custom/mailer/cert.pem
KEY_FILE = custom/mailer/key.pem
FROM = "Git" <[email protected]>
USER = [email protected]
PASSWD = yyy
ENABLE_HTML_ALTERNATIVE = false

Mailserver supports cram-md5:
250-mail.xxx.de
250-PIPELINING
250-SIZE 40000000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN DIGEST-MD5 CRAM-MD5 NTLM
250-AUTH=PLAIN LOGIN DIGEST-MD5 CRAM-MD5 NTLM
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

Password is 100% correct, tested with different clients. For me it looks like he doesn't even try to auth at all. Does anyone have an idea what's wrong here?

Thanks in advance!

Hi @zoh48gz04, does your password contain any special characters? It might be the problem. In my experience it is enough to put the password into single quotes. Could you try it please? If it fixes it for you I could create a PR for docs change, it is good to mention it somewhere.

That did the trick!

Thank you very much. :D
