SMTP on gmail.com works just fine for one address, but fails for another valid address. These settings work fine:
Email Server: smtp.gmail.com Email Port: 587 Email User: email@example.com Email Password: mypassword Use TLS: True
However, if I substitute in a different address -
firstname.lastname@example.org and its password - then I can't connect to SMTP.
I am CERTAIN this address and password are OK, I can log into Gmail with them. POP is enabled for the address.
Any ideas why Gmail SMTP might be objecting? Thanks!
