Hello,
we are using zoho SMTP, but it takes really long (4 seconds for each mail sending). I have tried to force persistent connection:
'host' => 'smtp.zoho.com',
'username' => '***',
'password' => '***',
'port' => 465,
'secure' => 'ssl',
'persistent' => true
but it does not work. Can you give me some hint?
Thank you very much
