How to setup email settings using gmail SMTP server?
What to add in From Name and From Address
I don’t know what your version of SuiteCRM is, so if you’re having trouble try swapping the two (From Name and From Address), there was a bug in the code using one in place of the other.
But normally with Gmail you are required to use your full email address in “From address”, and your name in “From name” (I don’t know if it checks anything about the name, or if it allows any name).
version is 7.10.1
Then make a good backup and try upgrading to 7.10.4, many email bugs were fixed since your version.
