In my mail server logs for all email senders address is added with hostname
Jul 22 22:25:54 shs2 postfix/local: 7174081826E: firstname.lastname@example.org, email@example.com, relay=local, delay=2.9, delays=2.3/0/0/0.56, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME) Jul 22 22:25:54 shs2 postfix/qmgr: 7174081826E: removed
The real user is firstname.lastname@example.org but in logs it is showing email@example.com as shown above logs and my hostname of server is shs2.onyxar.com. Why is it happen so. Did this will face any problems for my users. How to resolve this .
