Yes, it must be a misconfiguration but I cannot find it.  I have grep-ed /etc/postfix for all instances of localhost and there is nowhere an instance of localhost.com... Also, I have /etc/hosts with "127.0.0.1 localhost" and main.cf:"myhostname = mydomain.com" and "mydestination = localhost, localhost.localdomain" I am stumped...Anywhere else I should be looking?Would a catchall alias for root@localhost be a way around it?

  Hello all, I am seeing hundreds of lines like the one below in my mail.log from this specific IP address, which belongs to Google. Is there a way to determine why this "deferred (delivery temporarily suspended)" is happening?

Jun  5 19:09:32 arthemis postfix/error[86771]: 5D9D148296D: to=root@localhost.com, orig_to=root@localhost, relay=none, delay=4099, delays=4099/0.02/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to localhost.com[74.125.224.72]:25: Connection timed out)

"localhost.com" - you almost certainly are intending to connect to localhost (i.e. the local loopback address, 127.0.0.1) rather than the remote domain localhost.com.  So it looks like a configuration error.
