问题
My web host disabled proc_open function in php and I can't send emails anymore.
I get this error log:
proc_open() has been disabled for security reasons
I use laravel default Swiftmailer. What can I do?
回答1:
proc_open should only be required when Swiftmailer is using an external executable, like sendmail. You should still be able to use a different transport like SMTP, Mailgun, or one of the other drivers described in the docs.
As a test, try using the SMTP driver, and just entering your own SMTP mail details - whatever you use to send mail from your mail client. Try the following in your .env:
MAIL_DRIVER=smtp
MAIL_HOST=your.smtp.host // (copy from your mail client)
MAIL_PORT=your.smtp.port // (copy from your mail client)
MAIL_USERNAME=your.smtp.username // (copy from your mail client)
MAIL_PASSWORD=your.smtp.password // (copy from your mail client)
This is probably not suitable for a permanent solution but will let you test that you can send mail without proc_open. I use the free tier of Mailgun and can recommend it.

Check and changes are your php.ini has this line.
disable_functions = exec,system,dl,passthru,chown,shell_exec,popen,proc_open
Check this a list of functions disabled by safe mode here.
UPDATE
Once you found that, follow below instruction:
Remove the proc_open from the disable_functions at php.ini file
OR
Ask your hosting provider to remove the string above if you don't have an access/right to do that.
