I am trying to run WordPress off OpenWRT on a router. I have MSMTP installed and forwarding to my google account. Sendmail and the PHP mail() function both work, but WordPress still says I cannot send email and it may be disabled. I did some digging on this topic and a lot of people say that once they created a firstname.lastname@example.org account it worked. Since I am running MSMTP I don't have, nor can I create, accounts.
My biggest problem is I cannot get logged into WordPress at all. Every time I installed it I would get random 502 errors. It would install but not create my admin account. I found a workaround that said just manually add the account in MySQL and then have WordPress send you a new password. Hence my problem. No email means no new password, which means no admin account.
Thanks in advance, and sorry for the essay!
