Debug SMTP without any errormessage

[Anonymous]

Hi there,

since phpmail won’t alway work as expected, i’d like to use SMTP.
However, even with all SMTP settings set up correctly
– cannot send mails
– won’t get an errormessage

SMTP Provider 1: Strato

Server Server-Adresse Port
POP3 (Posteingang, SSL/TLS) pop3.strato.de 995
IMAP (Posteingang, SSL/TLS) imap.strato.de 993
SMTP (Postausgang, SSL/TLS) smtp.strato.de 465 / 587
Benutzername/Konto Ihre vollständige E-Mail Adresse z.B. mail@wunschname.de
Passwort ….

EME Settings:

Mail sending method SMTP
SMTP host smtp.strato.de
Mail sending port 465
SMTP encryption method: TLS (also tried NONE and SSL)
Use SMTP authentication? yes
SMTP Password: is correct, i tried via webmail
Verify SMTP certificates? no (for testing)
Debug SMTP? yes (but no usefull message)

When sending a test message, after 1min. or so i get an error:

There were some problems while sending mail.

SMTP connect() failed. 2: SERVER -> CLIENT:
2: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

well i know it uses an external library, but is there any chance to get a more intel about this?
Port problem? protocol Problem? encryption problem? Did it already test username/password?
I am totally clueless…

Greetings and thx in advance for your help 🙂

SMTP connect failed means that your webserver can’t access your configured mailserver in that port (typical a firewall issue). That’s also the reason why the message only arrives after a minute (port connect timeout).

After moving the WordPress-Installation to the same webhoster (strato) i could reach the SMTP-Server:

smtp.strato.de 465 (ssl)

Thanks for your help!
