postfix mail goes in junkmail

[mrwolf]

Hi,

(note: sorry for my bad english)
it's been three days since I swim in this nightmare.

I use Ubuntu Server 9.10 64bit

at first, sendmail was installed and everything was working great. all the email sent from forum and webform I host as been sent correctly in the reception box of the recipient. But I want postfix as MTA to do my delivery to all my virtual domain I host.

when sendmail is uninstalled and postfix installed and all services configured(php included) and restarted(apache included), when I send a email from command line or from web form, the email goes in junk mail for some ISP email address and for gmail and the email did'nt show at all for hotmail. but email sent from forum (phpbb) still goes in reception box like normal email do.

I tried do change the headers, who was working with sendmail, of the email sent from web form without success.

so I tried to uninstall postfix and reinstall sendmail, restarted all service and every thing was back to normal... email sent goes in reception box.

I tried it twice.... sendmail, postfix, sendmail, postfix and now back to sendmail for a working solution until I get postfix working.

I tried with spf entry in my dns, I tried allowed icmp packet from outside with iptables, I tried many different headers for my email. My ip is not blacklisted anywhere.

if anyone can help me fix this issue, I'll be glad ;)

Thanks

Did you try to use your ISP relayhost ?

[mrwolf]

I can't really, it's on a dedicated server.

[lisati]

Sometimes when you're running your own server and bypassing your ISP's mail system there's the potential for problems at the recipient's end, particularly if you're using what's perceived as a dynamic IP address or if your server's address is part of a block that has been "blacklisted". Some useful resources for checking if this is the case can be found at http://debouncer.com, http://www.blacklistalert.org/, and http://whatismyipaddress.com/staticpages/index.php/is-my-ip-address-blacklisted

There is a workaround for postfix so that it will use an ISP's system but I can't remember the details at the moment.

[mrwolf]

Thanks lisati

my dedicated server has a static ip with a matching dns and rdns.

After I checked all your link, I saw that my dedicated server is blocked from blackholes.five-ten-sg.com

but if I can't send email with postfix because of my blacklisted ip, why can I with sendmail?

[lisati]

The blacklists usually kick in at the receiver's end, not the sender's end. One problem I had to overcome for my server was that my ISP blocked port 25, which prevented me sending out email directly. Once I'd arranged a static IP, they were happy to unblock it.

[mrwolf]

I don't have problem with port, I have a dedicated server with all port unblocked, I can easily telnet my server on port 25.

with the same sender and receiver, an email sent with sendmail will pass but will be blocked when sent with postfix

[KB1JWQ]

Do you have matching forward and reverse DNS? If that's taken care of, and JUST postfix mail ends up getting rejected, paste the contents of your maillog so we can see what's happening.

Hi KB1JWQ,

yes as I already said, I have a matching dns and reverse dns.

this is my log:

Heh, sorry-- must have missed that.

Send yourself a message from Sendmail, then send yourself a message from Postfix. Are there any differences between the two? If not, please post full headers from both, I want to see where this spam-binning comes from. :-)

[KB1JWQ]

There we go.

Note the differences.
From: My Name <some_alias@gmail.com>

was accepted, but without a realname component your provider found the message spammier and junkbinned it.

It's not an MTA issue.

[mrwolf]

so I need to change the headers of my php script from "FROM: email@domain.com" to "FROM: NAME <email@domain.com>" because postfix doesn't send it properly?

both email used the same php script.

I readed on another forum that using this style: "name <email>" is wrong. finally is it the right way to do it?

[KB1JWQ]

Postfix serves as a drop-in replacement for sendmail; the From header isn't modified by anything it does.

As far as what's accepted, it depends on the remote site. Most clients throw that in, but it's your decision; RFCs 5321 and 5322 address this.

[mrwolf]

I did more test....

if the email is sent to hotmail, now it goes in the reception box with both sendmail and postfix, if the email is sent to gmail, it goes in junkmail with both postfix and sendmail.

at least postfix and sendmail now act the same...

Even if the email of the sender is invalid, for hotmail,now it goes in the reception box... wtf?

since my last test, the only thing as change is my ip was removed from the blackholes.five-ten-sg.com Blacklist

anyway... it works now so, thats' good.

Thanks everyone

[KB1JWQ]

Glad you got it sorted. If you're going to be sending a lot of volume you might look into getting a feedback loop set up with the major players.

[mrwolf]

thanks for the advice but I'll send under 100/day so I don't think I'll need anything else.

maybe in the futur.. if everything goes well for me ;)
