Unable to send/receive mails
I'm newbie on all this stuff, however, I have been able to run my web server and, it works. The thing is when I tried to create a mailbox for one of my domains, apparently it worked, because when I checked squirrelmail, the welcome message was there, but when I tried to send a mail to my hotmail and gmail account I couldn't make it, I receive a mail back saying :
<firstname.lastname@example.org>: host gmail-smtp-in.l.google.com[18.104.22.168]
said: 550-5.7.1 [MY PUBLIC STATIC IP] The IP you're using to send mail is not
authorized to 550-5.7.1 send email directly to our servers. Please use the
SMTP relay at your 550-5.7.1 service provider instead.
And when I tried to send a mail from my gmail account, it wasn't sent neither.
I bought the ispconfi 3 manual, but I even couldn't do it with it.
I bought a domain in godaddy, and I think my problem is the records but I'm not sure how to fix it, could you please help me? Thanks in advance
