I am using the following command to find log entries that are the result of a log in to the email server:

egrep '_login[^ ]' /var/log/exim_mainlog

That works fine to find entries that contain content like this:

P=esmtpa A=courier_login:[email protected] S=1573 id=f1cd08396,...

But what I need to do is to change my grep statement, so that it finds single word logins that do not use the @ sign, like so:

 P=esmtpa A=courier_login:name S=1573 id=f1cd08396,...

Where the log in before was "[email protected]", but in the second log entry, the log in used was only "name".

Is this possible using grep or egrep, perhaps in some kind of a compound statement?

Thanks much.
