Gmail requires port 465  and also it s the code from phpmailer

User · Answer

The code as listed in the question needs two changes   host    ssl   smtp gmail com    port    465     Port 465 is required for an SSL connection

User · Answer

Your code does not appear to be using TLS  SSL   which is necessary to deliver mail to Google  and using ports 465 or 587    You can do this by setting    host    ssl   smtp gmail com    Your code looks suspiciously like this example which refers to ssl    in the hostname scheme

I have a solution for GSuite accounts that doesnt have the   gmail com  sufix  Also I think it will work for GSuite accounts with the  gmail com but havent tried it   First you should have the privileges to change the option  allos  w less secure app  for your GSuite account  If you have the privileges  you can check in account settings- security  then you have to deactivate  two step factor authentication  go to the end of the page and set to  yes  for allow less secure applications  That s all  If you dont have privileges to change those options the solution for this thread will not work  Check https   support google com a answer 6260879 hl en to make changes to  allow less     option
