I used mxtoolbox.com to check my SMTP Status and i get this.

Code:

Connecting to xxx.xx.xxx.xx 220 cp.domain.tld ESMTP [657 ms] EHLO PWS3.mxtoolbox.com 250-cp.domain.tld 250-PIPELINING 250-SIZE 20480000 250-ETRN 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN [625 ms] MAIL FROM:<supertool@mxtoolbox.com> 250 2.1.0 Ok [625 ms] RCPT TO:<test@example.com> 454 4.7.1 <test@example.com>: Relay access denied [625 ms] PWS3v2 3282ms
