How can I debug problems with an email account ?

Ans:

Trace the path of the email when sent from the server and see what path it follows:

#exim –d2 –bt user@domain.com or

1. check for error if any under /var/log/exim_mainlogs files for email account.

2. check the MX record for the domain.

3.check if the email account exists on server.

4.check for the entry of domain /etc/localdomains, /etc/userdomains, /etc/valiases/domain.com and /etc/vfilters/domain.com

5.Make sure that the exim is upto date.
