<dd> <br>
<dd>Authentication & Identification<br>
</b><br>
<dd>To ensure that Gmail can identify you:<br>
<dd>· Use a consistent
IP address to send bulk mail.<br>
<dd>· Keep valid reverse
DNS records for the IP address(es) from which you send mail, pointing to
your domain.<br>
<dd>· Use the same
address in the 'From:' header on every bulk mail you send.<br><br>
<dd>We also recommend publishing an
<a href="http://www.google.com/support/a/bin/answer.py?answer=33786">SPF
record</a> and signing with <a href="http://www.dkim.org/">DKIM</a>. We
do not authenticate DKIM using less than a 1024-bit key.<br>
<dd>By authenticating, inline images you send will be shown
automatically. Recipients will not need to click the
"<a href="http://support.google.com/mail/bin/answer.py?hl=en&answer=145919">
Display images below</a>" link.<br><br>
<dd><a href="https://support.google.com/mail/answer/180707">Learn
more</a> about email authentication.<br>
<dd> <br>
<dd> <br>
<dd>SPF postoji , ali nije “signed” sa DKIM . Tek ulazim u
problematiku. Mada mislim da bi bilo moguce resiti problem kreiranjem
reverzne zone kod Ratka u JUNIS-u i kreiranjem PTR recorda. <br>

<dd>Hvala svima na odgovoru. <br>
<dd>SPF record , propisan postoji , ali za IPv4. Trenutno nas gateway ne
podrzava IPv6, te @MarkoZivkovic , sta dalje J . <br>
<dd>Ratko , mozemo li u tvom DNS-u da postavimo rekorde za nasu reverznu
zonu ? Da li to resave problem , ili nece moci da nadje
server, pa ni to ne resave problem ? <br>
<dd>Za ispadanje “glup u drustvu “ , bez brige. I ja sam rizikovao.
Ni meni teorija sa klijentima ne pije vodu, ali izgleda da to resave
problem . Na Exchange-u sam aplicirao fiks i to nista nije resilo. Tek
kad su klijenti to uradili isto kod sebe, proradilo je. Ajd, sad . Ko ima
objasnjenje nek izvoli.<br>
<dd>Ono sto je interesanto je da je problem samo sa @gmail.com domenom
. Domeni koji su na GoogleApsps-u , bez problema prihvataju postu.
Izgleda je i to kod njih u nekoj eksperimentalnoj fazi , pa je roll out
bio delimican . <br>

<dd>Koliko ja vidim problem je to ne postoji reverzna IPv6 DNS zona a
verovatno ni AAAA zapis<br>
<dd>za mail server. Zato jednostavno ne napravite reverznu IPv6 DNS zonu
za va opseg IPv6<br>
<dd>adresa i dodate jo AAAA zapis u direktnu zonu za va mail servver i
posao je reen.<br>
<dd>Postojanje SPF se podrazumeva.<br><br>
<dd>S druge strane, ne vidim kako IPv6 kod klijenata moe da pravi
problem ako je na mail<br>
<dd>serveru potpuno ugaen IPv6. Klijenti ne alju direktno mail-ove
Google mail serveru<br>
<dd>nego preko vaeg mail servera osim ako su vai korisnici namestili da
im mail klijent<br>
<dd>koristi Google mail nalog. S druge strane, i ovo je reivo pomoću
DNS-a, dodue malo<br>

<dd>Javio nam se veci broj korisnika prijavljujuci problem sa slanjem
poste na Gmail . Naime , posta se vraca i javlja se greska nalik ovoj
:<br>
<dd> <br>
<dd>mx.google.com gave this error:<br>
<dd>[2002:a063:98f::a063:98f 16] Our system has detected that this

<dd> <br>
<dd>Problem je u tome sto je Google pokrenuo prijem poste preko IPv6
protokola i dao mu je prvenstvo u odnosu na IPv4 . Detaljan opis problema
mozete naci ovde: <br>

<br>
<dd> <br>
<dd>Resenje problema zahteva i intervenciju na strani klijenta izgleda .
Mora da se iskljuci IPv6 na klijentu, a ne samo na mail serveru , a
to se moze jednostavno uraditi pokretanjem
<a href="http://go.microsoft.com/?linkid=9728869">OVOG Fix-a</a> koji je

koji je fixom automatizovan . <br>

<dd>Pitanje glasi, kako cemo da resimo ovaj problem ,a ne da koristimo
workaround ? <br>
