Hello :)

Are you receiving any specific error messages when sending/receiving emails? Try checking the following log files to see if you notice any specific errors:

# /var/log/exim_mainlog
# /var/log/exim_paniclog

Thank you.

I guess, the message id : 1VNrXN-0005kk-UX stats an email is sent from the server's lfd mentioning that there were a root login notification to the email address : [email protected] (is this an gmail.com address ?)

can you sent an email to any other gmail.com address ?, suspect that your server's ip is blocked at gmail.com, can you try

1. nslookup -query=mx gmail.com (from your server)

2. telnet gsmtp185.google.com 25 ( Replace 'gsmtp185.google.com' with the results from the DNS MX lookup ) from your server

3. Are you able to ping any/all of the servers listed in the MX record from your server ?

Did you make the initial post to this thread under of a different username? The reason I ask is because the initial problem on that post was sending/receiving any email, rather than an isolation of an issue with mail to Google. If that is the case, have you tried sending to another server to see if email works (E.g. Yahoo, Hotmail)?

Thank you.
