About a month ago my SMTP block opened (by default is blocked) but I haven’t test it until today, now I just tested it but it won’t send email. I think this is my very first time I’m trying my contact form to send email to my Gmail address, but somehow on my log Google said my IP address is spammy, how so?
Here’s part of the log with credential info redacted

Is this mean my server hacked? I’ve implemented all security protection from guides I found on DO guide and some other site. Please help me. Thanks

@MrWorldWideWeb Hey there,
These days the big mail providers like hotmail, gmail etc. have got their spamfilters pretty strict. This means you won’t be able to send any “legit” mails before you are verified. I won’t go into details alot right now, but think about configuring the following:
I don’t know if you want to learn about all of that & configurate it, but I recommend doing it ;) Maybe its something completely new, but learning new things is alwasy fun!
Hope I helped you with this.
