lost gmail? bulk yahoo?

[tchen]

I know it might not be scalix related, but since I'm using scalix and there are many expert here, I'm expecting I have good luck here:

Basically my server is kinda working, but not reliable, besides the above two problems, now
I got 2 more problems:

[1] gmail:
we just found that there is one user in our company, whose gmail is not accepted by our
scalix server. There is nothing in /var/log/maillog, /var/spool/mail/root, or /var/opt/scalix/tmp/smtp.log (I turned that on in smtp.cfg). There is no reject mail back to
his gmail, nobody in our server can receive his email.

However, we tried at least 10 other gmail accounts, none of them has any problem at all, we receives immediately. What could that be???

[2] yahoo
All our emails sent to yahoo comes into the bulk folders. I filled in a long form yahoo required and replied to mail-abuse-bulk@cc.yahoo-inc.com, get no reply. Did any of
you had this issue? What else should I do? Or is it not yahoo's spam filter's problem?
could it possibilly be that my ISP (godaddy) that cause such problem?

Thank you guys in advance, any suggestion is very welcome, Thank you.

Hi Tingdong,

1) Regarding gmail, so, this is an incoming message being sent from one particular user's gmail account, right? If you've enabled DEBUG_LOG=TRUE and restarted the smtp relay and you don't see that message coming in via the log, then the message is being diverted upstream somewhere. Do you have a perimeter SMTP host or anti-spam/anti-virus appliance that might be eating those messages? Are you certain that the gmail user is sending to the correct address?

2) If yahoo is putting messages from your Scalix system into their bulk mail folder, perhaps it's because a reverse lookup of your Scalix Server's IP address returns a "pool" address from your ISP rather than your server's domain name. That's often a trigger for various anti-spam filters. You need to talk to your provider and have them change it on their DNS server.

Thanks,
Rachel

Re 2)

The DNS record you need for the MX hostname is a PTR record.

Did you ever resolve your gmail issue? I am having the same problems.
