comment Sendmail Spamming Recipient
Gmail as a system has these limits. This has nothing to do with mail hosting offered by Gmail.

To rebuild and recompile in CentOS, after you edit sendmail.mc you run /etc/mail/make followed by a service sendmail restart.

comment Ubuntu sendmail “Relaying denied. Ip name possibly forged” (in reply to rcpt to command)
It is exactly the rewrite that bugs me. Could it be that because subdomain.domain.com has two entries in /etc/hosts of which 127.0.0.1 is the first one, that it gets "overwritten" by localhost.localdomain somewhere in the process before the rule sets are applied?

But this does not explain why email gets rejected by the Relay_ok rule set (This is where the failure message gets generated)

Can you also provide us with the contents of /etc/hosts?

revised Why does Exim's “sendmail” apparently do nothing for about 5 seconds before sending any mail?

It would also help if the OP told us the exact domain name for which he is having problems.

comment NOQUEUE: SYSERR(root): opendaemonsocket: daemon MTA-v4: cannot bind: Address already in use
For someone with little experience with mail systems, I tend to believe that postfix is easier to setup. Others will say exim. You still seem to be having problems with your sendmail installation too, so it is best that you remove sendmail too, reboot the machine and reinstall it before continuing wth your setup

comment Is it necessary to manually rebuild a sendmail.cf file or is this done automatically on service restarts?
So if you change .mc and then type make all does it build the .cf? If yes, then it rebuilds on restart. The easiest way to check all this of course is to touch /etc/mail/sendmail.mc wait 10 seconds and then service sendmail restart. Then ls -l /etc/mail/sendmail.* and check the dates.

comment sendmail on centos drops connection after n e-mails sent
Welcome to SF Andrzej! Since this is a VM, I am assuming that in the case of a single mail per recipient, this will be queued locally by a web (php) form, so it might be a good idea to follow Vixie's advice and have QUEUE_LA and REFUSE_LA have the reverse values (deny accepting connections in order to clear the queue first).
