The wierd thing about this is that it appers to effect only a
couple of gmail usres. For example mail from my gmail account
goes through just fine
Are you running a greylist perhaps? Either way, Google 'slams'
email. In other words they try once and if the email cannot be
delivered before the time out, the failure response is sent. I run
milter greylist on one of my sendmail servers and had to include an
exception for gmail. Sad but true. Gmail is not really a fully
compliant email system but they do a lot of other things very good.
Yes I am running postgrey now.. but this occured even before I added
postgrey
plus, thetre still is the issue that some accounts make it and some
don't
There is no record of any rejection in my logs
I'm at a bit of a loss about why before postgrey. It suggests that
the mailserver is just not answering fast enough, which can vary
based on load at a particular moment. Gmail might have a short
connection attempt time set as well? Obviously slamming reduces loads
to a huge degree... shorter connection times would also reduce loads.
It is for the most part a 'free' service. Perhaps premiere gmail
accounts are handled diffently?
As for postgrey, I have not used that but you need to add an
exception for gmail. I assume postgrey is like milter greylist in
that it keeps a list of recent IP addresses to allow incoming email.
Gmail certainly has lots of IP addresses for their mailservers. It
could be simply hit or miss based on which are currently on that
allow list. This would show as a sporadic issue. Another test, if you
know any of the gmail people which are receiving the failure notices,
is to have them try once, then again some minutes later which is
greater than you postgrey time setting. Then again, I'm not sure
every email sent from any particular gmail user always come in from
the same IP address.
I had this issue even before I added post grey to my configuratioin..
I am getting no errrors or bounces
I have had the user resend
again the wired things are
1) one gmail account works while others don't (which would support
one server is really slamming while tjhe other isn't
Or some are whitelisted by postgrey while others are not. Also, is it
possible that loads are going high at times, causing time outs? Gmail
will just give up while almost all others simply retry later.
2) absoultely no error mesages on my server.. its like it boucned off
an invisible shield
Do your postgrey logs show? If it is sending a delay response, it would
only show in the logs of that 'invisible shield'. (again, sorry I'm out
of my realm here as I only have experience with milter greylist on my
backup sendmail server. I do remember setting several IP address ranges
to get around gmail slamming.)
Remember, the error message is generated by gmail, not your system. You
could grep logs for the sender's email address.
Best of luck.
