comment Sendmail trying to deliver mail locally, not honouring mx record
You need to produce a new sendmail.cf from sendmail.mc and restart sendmail. In Debian I run sendmailconfig. In FreeBSD I execute make restart while inside /etc/mail

comment sendmail not sending mails to @samedomain (target mail is on google apps)
I have not done this, as I do not relay through smtp.google.com, but you may try phinesolutions.com/sendmail-gmail-smtp-relay-howto.html

I live in Greece and have been a member of USENIX and SAGE since 1997. LOPSA (I think) is more US oriented.

comment Why is it necessary to set a netmask of 255.255.255.255 for “alias” addresses in FreeBSD?
However a "point-to-point" address is a /31 or a /30. A /32 describes a single host.

comment Email sent from non-Google Apps MTAs sometimes takes hours to show up in a Google Apps email box, why?
I would recommend an SPF record like "v=spf1 include:aspmx.googlemail.com a a:tampabay.rr.com ~all" that includes all servers that send email on behalf of this domain

There seems to be a problem with your DNS setup. www.openspf.org does not see any MX records (nor do I querying from OpenDNS) but Google seems to see it (but without TXT/SPF records).

@Robert Butler: I do not know your domain. Depending on how you've setup its DNS settings, it may or may not include an SPF record that has Google's mail servers in it. If it has an SPF record, then you have to include every server that sends mail for this domain in the record. If you do not have an SPF record, creating one that includes Google's mail servers and the other sending servers that you are using may help in improving your delivery times. See Google's help page on SPF also google.com/support/a/bin/answer.py?hl=en&answer=33786

If the "external" mail servers are always the same, adding them in an SPF record about your domain.

comment php mail() from localhost
No. When people say that there is a problem with your DNS, they mean that your server cannot resolve any name. Post the contents of your /etc/resolv.conf
