Wie Emails via PHP verschicken?

Benjamin83 · Donnerstag um 09:43

Moin, und erstmal allen ein gures Jahr 2025!

Ich versuche seit Wochen (mit Unterbrechung natürlich) ein Kontaktformular für eine kleine Vereinswebseite zu realisieren. Ich hab auch schon im Mail Untefohrum gepostet, aber leider hat niemand reagiert: https://www.synology-forum.de/threads/versenden-von-ext-mails-aus-webstation-php-problem-mit-usern.136682/

Vielleicht habe ich ja hier mehr Glück - kann ja nicht der Einzige sein, der gerne Mails verschicken möchte...

Aber mal der Reihe nach:

Ich habe DSM 7.2.64570 und darauf in der Webstation 2 "Webportale":

Eine private statische Hompage (Nur HTML): DomainA.de
Eine Kontaktformular für einen kleinen Verein mit PHP 8.2: backend.DomainB.de

Die Systemmails von meiner Synology werden über einen externen Webserver (googlemail) versendet. Ein Mailserver war bisher auf der syno nicht installiert.
Ich habe jetzt "Synology Mail Server" installiert und die DomainB unter SMTP als Hostname (FQDN) eingetragen. (Ich habe es als Hostname wie auch als "Zusätliche Domain" ausporbiert, scheint keinen unterschied zu machen.
SMTP-Authentifizierung habe ich deaktiviert.
Testweise habe ich auch ein SMTP-Relay aktiviert. Das scheint zu funktionieren, ändert aber nicht viel am Problem.
DomainA benötigt keine Emails über die Syno.

Das PHP-Formular stammt von hier: https://www-coding.de/individuelles-kontaktformular-mit-captcha-in-php/
Der fürs versenden der Mails entscheidende Teil ist mMn das hier:

PHP:

$adminMail = 'webadmin@DomainB.de;
//$fromMail = "noreply@".$_SERVER['HTTP_HOST']; 
$fromMail = 'Info@DomainB.de';
...
mail($adminMail, $mailSubject, $mailText, $mailHeader."Content-type: text/plain; charset=utf-8"."\r\n");

Unter den Scriptspracheinstellungen habe ich den sendmail_path von PHP angepasst auf "/var/packages/MailServer/target/sbin/sendmail -t"
Ich kann das Formular erfolgreich aufrufen, auslösen und auch eine Mail generieren. Diese kommt bei "Synology Mail Server" an, aber nicht weiter.

Die Fehlermeldungen lassen immer wieder auf Probleme mit den Benutzen Usern schließen.
Ich habe also sowohl "Benutzernamen" als auch Domains im PHP benutzt die es in der Syno als lokale nutzer gibt, als auch solche die es nicht gibt.
Einen User "http" habe ich auf der Syno nicht, nur eine Gruppe.
Die Fehlermeldungen im postfix-Log des "Synology Mail Server" unterscheiden sich auch, aber weitergekommen bin ich mit keiner...

Ich habe stundenlang probiert und bin mir sicher ich stehe irgendwo auf dem Schlauch. Fragt sich nur wo...

Ich bin absolut nicht auf einen Lokalen Mailserver wie "Synology Mail Serve" fixiert. Von mir aus wäre es genauso i.O. die mail über den externen Mailserver von DomainB (Der den ich auch als Relay ausprobiert habe) zu versenden. Ich weiß nur nicht, wie man das mit PHP bewerkstelligt.

Im Endeffekt wäre ich selbst ein anderes Formular oder eine andere Websprache i.O. für mich, wir reden hier von einer Vereinsseite mit gerademal ein paar aufrufen - im Monat. Trozdem muss es hal eine Kontaktmöglichkeit geben.

Hier mal ein paar Beispiele für Vesuche dich ich gemacht habe:

Hallo Benjamin83,

Bücher und Hardware zum Thema gibt es bei Amazon: Wie Emails via PHP verschicken?

Hab ich getan, bin leider auch nicht weitergekommen. Zum einen fehlt PEAR seit DSM7 in den Paketen, und zum anderen hab ich auch kein brauchbares Tutorian / nutzbares Formular gefunden.

You can use ssmtp to send emails from a Synology. To use ssmtp you need to setup email notifications in "Control Panel > Notification > Email > click on Setup button" .

In bash scripts I use:

Bash:

# Send email function
# shellcheck disable=SC2329  # Invoked indirectly
send_email(){
    # $1 is $to_email_address
    # $2 is $from_email_address
    # $3 is $Backup_Directory
    # $4 is $email_contents"
    # $5 is $subject
    # $6 is $mail_body


    if [[ ! -f "$Log_File" ]]; then
        echo -e "\nWARNING Cannot send email as directory $Log_File does not exist"\
            |& tee -a "${Err_Log_File}"
    elif [[ "${3}" == "" || "${4}" == "" ]]; then
        echo -e "\nWARNING Send email failed. Incorrect data was passed to \"send_email\" function"\
            |& tee -a "${Err_Log_File}"
    else
        if [[ -d "${3}" ]]; then  # Make sure directory exists
            if [[ -w "${3}" ]]; then  # Make sure directory is writable
                if [[ -r "${3}" ]]; then  # Make sure directory is readable
                    echo "To: ${1} " > "${3}/${4}"
                    echo "From: ${2} " >> "${3}/${4}"
                    echo "Subject: ${5}" >> "${3}/${4}"
                    echo "" >> "${3}/${4}"
                    cat "$Log_File" >> "${3}/${4}"


                    #if [[ "${1}" == "" || "${2}" == "" || "${5}" == "" || "${6}" == "" ]]; then
                    if [[ "${1}" == "" || "${2}" == "" || "${5}" == "" ]]; then
                        echo -e "\nWARNING One or more email address parameters [to, from, subject,"\
                            "mail_body] was not supplied, Cannot send an email" |& tee -a "${Log_File}"
                    else
                        if ! command -v ssmtp &> /dev/null  # Verify the ssmtp command is available
                        then
                            echo -e "\nWARNING Cannot Send Email as command \"ssmtp\" was not found"\
                                |& tee -a "${Log_File}"
                        else
                            local email_response
                            email_response=$(ssmtp "${1}" < "${3}/${4}"  2>&1)
                            if [[ "$email_response" == "" ]]; then
                                domain=$(echo "$to_email_address" | awk -F '@' '{print $NF}')
                                echo -e "Email sent successfully to $domain" |& tee -a "${Log_File}"
                            else
                                echo -e "\nWARNING An error occurred while sending email."\
                                    "The error was: $email_response\n\n" |& tee -a "${Log_File}"
                            fi   
                        fi
                    fi
                else
                    echo -e "Cannot send email as directory \"${3}\" does not have READ permissions"\
                        |& tee -a "${Log_File}"
                fi
            else
                echo -e "Cannot send email as directory \"${3}\" does not have WRITE permissions"\
                    |& tee -a "${Log_File}"

        else
            echo -e "Cannot send email as directory \"${3}\" does not exist" |& tee -a "${Log_File}"
        fi
    fi
}

# Send log via email if both logging and emails are enabled
if [[ $to_email_address && $from_email_address ]]; then
    echo -e "\nSending email..."
    email_contents="email_contents.txt"
    send_email "$to_email_address" "$from_email_address" "$Backup_Directory"  "$email_contents" "$Nas - $script log"
fi

You should be to strip out what you need and convert it to php.

@DaveR Do you know if or how to send file attachments using ssmtp?

DaveR · Gestern um 11:07

I believe ssmtp is the same as msmtp, and you can't send attachments with msmtp.

Mutt works with the same commands as msmtp (as mutt has smtp built-in) but mutt also supports emailing attachments. Replacing "msmtp" with "mutt" in my code above works.

To use mutt to send an attachment. Something like the following should work but I've not tried it.

mutt -a /path/to/attachment.ext "${1}" < "${3}/${4}"

or

mutt -a /path/to/attachment.txt -s subject — recipient@domain.com < /path/to/body.txt

In DSM you can install mutt from synocommunity.

Tommes · Gestern um 11:54

I will definitely save the ssmtp script and have a look at Mutt in the coming days. At the moment I have only asked for someone else. Thanks for your help.
