I'm seriously out of ideas and I'm now wondering where to go on next.
Could anyone tell me what to do when you get this message?
SMTP error from remote mailer after RCPT TO:<[email protected]>:
host xxxxx.net [xxx.234.184.xxx]: 550-Verification failed for
550 Sender verify failed
I've tried checking the MX record, it's correct. I've even tried changing the permission on the mailboxes and etc. I've done practically everything I know which could be wrong but till now, it's still giving me this problem.
I'm totally out of ideas and clueless on what's going on. Could someone be nice enough and help me out here?
