OT: Problems sending emails to gmail. I used postfix debian install (based falko)
Since we installed (or maybe gmail activated spam control) we have problems to send emails to gmail.com :(
Its a real problem or us because some customers use gmail accounts. I have setup SPF records, ptr, and so. so don't know what could be wrong :(. Of course, i'm sure we don't send spam!. the only difference between our installation server and falko howto, we added maia mailguard to server.
I post you the message when we send email to gmail (of course we tried to contact gmail, and it's imposible, they ghave an autoresponse support and that's all, we dont get reply from human):

What could be wrong please? i searched in google for info, and many people have same problem :(
By the way our ip is no in blacklist, i checked it in dnstuff.
thanks for help
no, from your IP there have been sent quite a number or spam to gmail... it seems people did complain and so you landed on the gmail blacklist....
Maybe you have an open relay server and someone is abusing it?
If you host your server on a dynamic IP address or DSL line, it is blacklisted almost automatically, no matter if you send spam or not.
If you have a static IP address, you should check your mail log if there''s much more email traffic than you expected, and you should also check your mailqueue with
Also, what's the output of
sjau,as i asaid no blacklist, our users dont send spam :(
Falko, static IP , we have a range of IP's
It's a closed mail server with sasl auth.
# postqueue -p

thanks for help dude.
Did you check the known blacklists such as SORBS?
re Flako, thanks for help
No one is of servers are doind spam. I added them because they are static ip adsl of customer and the server is only for this customer, server only has 2 domain, tecnoretail for testing pourposes and the customer domain , so i'm really sure no spam and i checked server logs and no spaming :(
any ideas? some one said me i have to check HELO, PTR , DNS and so, but i checked and i don't see nothing strange :(
I checked sorbs and many others and no blacklisted:
[220.127.116.11] was not found in the SORBS database.
Did you visit this page? http://www.google.com/mail/help/bulk_mail.html
Maybe one of your customers sent as newsletter which was reported as spam to Google... Anyway, I'd try to contact Google and find out what caused the problem.
I tried contact google 5 times, its imposible :( they have an auto response and then they say each time i should to send emailes, and i sent 10 different examples and it' imposible,no answer from them. i have been contacting them during 1 month so it's imposible :(
I asked my customer if he sent a newsletter or something like that, and he said me no, i checked logs and no mailing list, no newsletter nothing masive :(
I checked the web page bulk in gmail, so i created spf records they recomend but same problem.
I've just checked your IP address here: http://www.mxtoolbox.com/blacklists.aspx
and it really seems to be ok. :confused:
Yes, im no backlisted. well, thanks for help, i will have to redirect all .gmail.com to external smtp server to allow send emails to gmail :(
And... if some gmail admin is reading this psot, please, check your config because lot of people have same problem like me. :)
thanks for help.
