swiftmailer | Comprehensive mailing tools for PHP | Email library

I've got problems with sending emails after updating a Laravel 8 project using the Metronic 8 theme to Laravel 9. I didn't change any of my code related to emails, but now I got this error using the Sendmail driver :

An email must have a "To", "Cc", or "Bcc" header. {"userId":6,"exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "To", "Cc", or "Bcc" header. at /home/myhome/public_html/myproject.com/vendor/symfony/mime/Message.php:128)

Controller

I created a new laravel project ,and I want to use Adminlte 3 as a template ,so I run this command that i found in the documentation :

I'm a beginner in Symfony and would like to know how to deal with the following installation issue: I'm using Symfony 4.4 and trying to install Swift Mailer. Following the documentation on this link, when I ran the following command composer require symfony/swiftmailer-bundle , I got this error message:

Your requirements could not be resolved to an installable set of packages.

Problem 1

• symfony/web-server-bundle is locked to version v4.4.0 and an update of this package was not requested.
• symfony/web-server-bundle v4.4.0 requires php ^7.1.3 -> your php version (8.0.12) does not satisfy that requirement.

Problem 2

• laminas/laminas-code 3.4.1 requires php ^7.1 -> your php version (8.0.12) does not satisfy that requirement.
• symfony/proxy-manager-bridge v4.4.34 requires friendsofphp/proxy-manager-lts ^1.0.2 -> satisfiable by friendsofphp/proxy-manager-lts[v1.0.5].
• friendsofphp/proxy-manager-lts v1.0.5 requires laminas/laminas-code ~3.4.1|^4.0 -> satisfiable by laminas/laminas-code[3.4.1].
• symfony/proxy-manager-bridge is locked to version v4.4.34 and an update of this package was not requested.

Any idea how to handle that?

Update:

This is my composer.json file:

after i click register button i get the error bellow Swift_TransportException Process could not be started [The system cannot find the path specified. ] and whene i go to phpmyadmin it seems that i have the new user record in my database i don't know what's the relation between the auth and swiftMailer i already tried clearing the config using php artisan config:clear changing MAIL_DRIVER, MAIL_HOST, MAIL_PORT i don't know what to do

this is my .env file

Some question's, and articles I've been reading regarding EML creation

• How to verify DKIM signature from an e-mail with openssl?
• PHP library to generate EML email files?
• https://www.icosaedro.it/phplint/mailer-tutorial/index.html
• https://coderedirect.com/questions/25620/php-library-to-generate-eml-email-files (This one is interesting, but it would need extending for DKIM signatures)
• https://www.example-code.com/phpExt/smtp_loadEmlAndSend.asp (only does SMTP send)
• https://community.apachefriends.org/f/viewtopic.php?t=79968&p=270281 (this works great for Linux, haven't been able to find Windows equivalent)
• Use of mailtodisk / mailoutput in XAMPP for Linux (Great concept)
• https://swiftmailer.symfony.com/docs/introduction.html (This is from Symfony yet to see if works without Symfony but no longer maintained)

I can't seem to find any standalone class files that will generate the contents for *.eml that can be either stored into file (using file_put_contents) or temporarily into a variable.

The idea is that I can create my *.eml file server-side I could use the contents to verify a DKIM signature, without having to actually send an email.

I did find one library phplint that does what I want, but it is far too big for what I need (635 Files, 53 Folders 7.84 MB (8,224,768 bytes)).

I would like to send newsletters via SwiftMailer, but there should be an emoji in the subject of the email. I think the right charset is utf8mb4 but how can I change the charset for the subject?

It worked for the body of the Swift_Message Class because I defined the Content-Type like following:

$message->setBody($html, 'text/html');

I faced with error when use mailcatcher with laravel ( "laravel/framework": "^8.54",)

I work on a macbook (Catalina 10.15.7) and develop a webapp on my local machine. I use the mailtrap.io email testing service to check outgoing emails. I haven't changed anything, but a few days ago the mailtrap service gives back the below error message:

ErrorException stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed Illuminate\Foundation\Bootstrap\HandleExceptions::handleError vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:94

The same code and call works fine from the remote server, so it seems that the problem is related my local mac machine.

After some googling it seems that this issue is related to the expiry of DST Root CA X3 certificate. I read about two possible solutions for the problem:

1. Remove the expired certiface and install new ones.
2. Update OpenSSL on my machine

Approach #1 I tried, but it did not help. I removed the DST Root CA X3 section from /etc/ssl/cert.pem file and removed all DST Root CA X3 instances using the Keychain Access app. Then I installed the ISRG Root X1 and ISRG Root X2 using the Keychain Access app setting them to always trust. Unfortunately I still get the same error message after rebooting.

Approach #2 The second approach would be update OpenSSL on my machine. The "openssl version" command tells me that I have LibreSSL 2.8.3 on my machine, so I assume this is what I need to update. Checking the libreSSL release notes it seems that there already a fix for this problem. I installed the latest LibreSSL (3.3.5) and added it to the PATH variable, but I still get the same error. It seems that whoever would need the higher version of LibreSSL, it does not use it.

So my question:can somebody explain to me, which component from the above chart should use the higher version LibreSSL with the fix to avoid the original problem with the mailtrap connection? Is it the OS, MAMP, Laravel, the SwiftMail component or my Webapp? Based on this, how do I tell that component that it should use the LibreSSL (or alternatively OpenSSL that I could also install) with the fix? Or is there a better solution to this problem?

Thanks, W.

In my .env file I have:

MAILER_URL="smtp://localhost:25?encryption=&auth_mode="

But if I send a mail the log shows:

Could not send mail: Failed sending mail to following recipients: {{ recipients }} with Error: Unable to connect with STARTTLS. Error Code:0 Template data ...

Looks like it tries to use TLS but I don't want to. It worked before. Maybe it got broken by an update.

Looking at the documentation I also tried encryption=null with same result.

Debugging in vendor/shopware/core/Content/Mail/Service/MailerTransportFactory.php:36 I made sure my MAILER_URL was used.

I am using shopware 6.4.1.1 with symfony/mailer v5.2.10

How can I get mails working again?
