The mxtoolbox tools look GREAT!
Unfortunately I had a problem adding my server to the free monitoring service.
It appears the mxtoolbox script fails to identify itself at HELO with a fully-qualified domain name. This is not conformant with RFC 2812, which requires a FQDN.
Feb 5 17:38:46 atomic postfix/smtpd[7728]: connect from mxtb-pws1.mxtoolbox.com[64.20.227.131]
Feb 5 17:38:46 atomic postfix/smtpd[7728]: NOQUEUE: reject: RCPT from mxtb-pws1.mxtoolbox.com[64.20.227
.131]: 504 5.5.2 <mxtbpws1>: Helo command rejected: need fully-qualified hostname; from=<no-reply@mxtool
box.com> to=<braddock@braddock.com> proto=SMTP helo=<mxtbpws1>
I have PostFix configured to reject such non-conformant mail (it REALLY helps with spammers, who can't seem to write a conformant spambot).
I look forward to using the service soon!
