I'm getting this error when I hit submit on my contact form
Failed to authenticate on SMTP server with username "[email protected]" using 2 possible authenticators.
Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data ".
Authenticator PLAIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data ".
As far as I know all my details is corrected and my cpanel php is 7.3.
On my live site the contact form works correctly, but on my localhost I'm getting the above mentioned error. I used mailtrap to test out my contact form and that worked as well.
I can't understand why I'm getting this error when those details is working fine on my live site.
this is my .env
MAIL_DRIVER=smtp
MAIL_HOST=mail.domain.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=null
In general you need an SMTP server to send emails through SMTP. Your local environment doesn't have this default. You can use alternative tools like mailhog to catch the SMTP calls and watch the email in there.
So locally using SMTP is always an issue :P
If your mail server password contains a # then you should quote the environment string since everything after # will be taken as comment (starting in Laravel 5.8)
@snapey Take a lots of love brother.....It's worked successfully Alhamdulillah
I loooooooooooooove you, 4hours i was trying to fix, get headache of that. thanks dear
@Snapey But my own password doesn't even contain # so what is the issue when all the smtp credentials are correct and it still throws in this error
@Snapey thank you very much
@Snapey Thanks, faced the same error now, I had a # in my mail server password, I had to quote it and solve the error
@SNAPEY - Thank you so much. That worked I did have a # in my password
@snapey You saved my day) thanks
Another one that you saved the day. Thank you so much, @snapey !
Could you please show me where to find the # mentioned in this thread? thank you so much! I am an amateur!
@phuthao you might not have one. It is saying that if your secrets in .env contain # then you must quote the string eg;
MAIL_PASSWORD = r39304#d^fd
The # marks the start of a comment, so the password ends up being 'r39304'
The solution;
MAIL_PASSWORD = "r39304#d^fd"
@Snapey Thanks Bro
@snapey I'm so glad I came across this solution. My password actually started with #. Thank you soooo much.

@292marxist have you enabled less secure apps in your google settings?
@Snapey Is that needed to be done for this issue because this issue is only occurring sometimes in my system not all the time
@292marxist why dont you start your own question and put the correct information in it?
@snapey Hey... any idea what's wrong here?

none of these works for me. I think laravel should improve on this. There seems to be no consistency with this error and a clear explanation on what the cause is.
@Gemley If you're having SMTP connection issues, it probably has nothing to do with Laravel. You should make a separate thread and explain your issues there (with full error messages).
