Problem with postfix verification

[comettom]

Hello, i cant send/receive emails from/to some servers... I receive a log like this:

Oct 27 15:43:12 XXXXX postfix/smtp[2550]: DD1CAA4113E: to=<gerencia@XXXX.net>, relay=XXXXX.net[174.132.XXX.XXX]:25, delay=1.9, delays=0.17/0/1.4/0.32, dsn=5.0.0, status=bounced (host trendigital.net[174.132.XXX.XXX] said: 550-Verification failed for <info@XXXXX.info> 550-No Such User Here 550 Sender verify failed (in reply to RCPT TO command))

my server is XXXX.info ... the server with i want to send/receive is XXXXX.net ...

What is the problem? postfix configuration? certificates?

Looks like the person your sending mail to doesn't exist at that domain

"status=bounced (host trendigital.net[174.132.XXX.XXX] said: 550-Verification failed for 550-No Such User Here"

Hello Stone, i have configured 2 emails in ehcp server, and exist and are functional...

I have my server XXXX.info with ehcp (its very good)... i can send/receive from gmail, hotmail, and much more...

But i have other domain XXX.net in hostgator server, and i cant send/receive and i receive this log... i have the same problem with other servers... not only hostgator...

In /var/log/mail.warn i receive this log:
Oct 27 16:20:58 trendigital0 postfix/smtpd[2894]: warning: cannot get RSA private key from file /etc/postfix/smtpd.key: disabling TLS support
Oct 27 16:20:58 trendigital0 postfix/smtpd[2894]: warning: TLS library problem: 2894:error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch:x509_cmp.c:406:


Because this i think is problem from certificates smtpd.crt... but i dont know....

since you can get/send email from gmail, your mail working basicly.
I have no idea, why hostgator makes such error.
