Port 25, smtp.t-2.net, "SPF record"

Je že res, da skoraj nima veze, preko katerega smtpja pošiljaš mail, sem pa opazil, da nekateri spam filtri zavračajo pošto, ki ni poslana z iste domene. Recimo, imam najdi.si mail in ga sedaj pošiljam preko T2, mi nekateri spam filtri zavrnejo pošto, ker ne ustreza tistim SPF-record pravilom, al kaj so že (ni mi čisto jasno:).

Kolega mi je tudi nekaj omenjal (jaz ne uporabljam T-2 ), da naslovniki ne dobijo poste, kadar jim poslje sporocilo na @hotmail.com ali @aol.com preko smtp.t-2.net

Zato sem si ogledal nekaj "DNS reportov" ...

You have an SPF record. This is very good, as it will help prevent spammers from abusing your domain. Your SPF record (I don't check to see if it is well designed!) is:
"v=spf1 include:spf-a.hotmail.com include:spf-b.hotmail.com include:spf-c.hotmail.com include:spf-d.hotmail.com ~all" [TTL=3600]

Your domain does not have an SPF record. This means that spammers can easily send out E-mail that looks like it came from your domain, which can make your domain look bad (if the recipient thinks you really sent it), and can cost you money (when people complain to you, rather than the spammer). You may want to add an SPF record ASAP, as 01 Oct 2004 was the target date for domains to have SPF records in place (Hotmail, for example, started checking SPF records on 01 Oct 2004).

BTW, tukaj je nedavni clanek na to temo:
http://www.clickz.com/showPage.html?page=3623869

Sender Policy Framework (SPF). SPF is a solution similar to Microsoft's Sender ID, storing authentication information in DNS text records. Developed as an open-source project by Pobox, SPF has been adopted by several mainstream companies, including AOL and Google. SPF is also incorporated in the recent version of the popular content filter, SpamAssassin.

Na openspf.org lahko preberš tudi tole:

We're in an early-adoption stage right now: we need lots of domains to publish SPF records so we can test client libraries against them. Please join the mailing list and say which domains you've published SPF for!

Kolega mi je tudi nekaj omenjal (jaz ne uporabljam T-2 ), da naslovniki ne dobijo poste, kadar jim poslje sporocilo na @hotmail.com ali @aol.com preko smtp.t-2.net

SPF je namenjen preverjanju pošiljatelja in ne prejemnika. Torej na pošiljanje sporočil na hotmail.com in aol.com SPF ne vpliva, vpliva pa na sporočila, ki bi jih tvoj kolega pošiljal z naslovov @hotmail.com ali @aol.com čez smtp.t-2.net .

Tudi za že omenjeni najdi.si je rešitev enaka kot za email.si - sporočila se pošilja čez njihov SMTP strežnik (mail.najdi.si) z uporabo SSL avtentikacije (port 465).

Hmm ...

Torej ce imam email naslov <moj.email@druga-domena.com> na nekem host strezniku (npr. ucvhost.com) in sem do sedaj uporabljal njihov SMTP streznik (port 25 - ne podpirajo SMTP via SSL), potem po novem ne morem vec zanesljivo posiljati elektronske poste preko t-2.net (ce nimam staticnega IP-ja) ...
Oziroma moram uporabiti "UCV Host Secure WebMail" (ali pa mail2web.com) preko brskalnika in ne preko email klienta!

Ali to drži ?

Lp, Roman

P.S. Koliko dni traja preklop na staticni IP ?

[mitja_i]

Po mojem mnenju, če tvoj host ne podpira SMTP via SSL potem to ni nek dober host in ga je bolje zamenjat...
Statiko dobiš v nekaj dneh. Odvisno od gužve

[modicr]

Zivjo!

če tvoj host ne podpira SMTP via SSL potem

Ni dokumentirano, ampak sem probal in v OE-ju nastavil
"This server requires a secure connection (SSL)"
in port spremenil iz 25 v 465 ter odkljukal
"My server requires authentication".
Zacuda dela, vendar mi ob posiljanju prvega sporocila javi

"The server you are connected to is using a security certificate
that could not be verified.

The certificate's CN name does not match the passed value.

Do you want to continue using this server?"

Odgovorim "Yes" in sporocilo je uspesno poslano. A kdo ve, kako
onemogociti zgornje vprasanje???

BTW, ali bo T-2 uvedel SMTP via SSL?

Hvala, Roman

[Cobane]

BTW, ali bo T-2 uvedel SMTP via SSL?

Ali ga nisi ravnokar uporabljal?

Kar se pa tiče tistega opozorila, si pa spremeni smtp.t-2.net v md2.t-2.net. IP je isti le da se certifikat nanaša na md2 namesto na smtp - zato tudi sporočilo.

[modicr]

Hvala za md2.t-2.net.

Ali ga nisi ravnokar uporabljal?

To se je nanasalo na ucvhost.com (uporabljal sem njihov
SMTP/SSL).

Lp, Roman

[BOBI]

Eno laično vprašanje!

Je potem pošta kaj hitrejša če preklopim iz SMTP na md2 ?

[T2_Delavec]

Ne, isto je.

[BOBI]

Pol pa nč, bom poštarju moped kupu

[Jaka]

So danes kakšne težave z elektronsko pošto?

[Slowhand]

ne,so že skoz,tko da naj te ne skrbi...

[Jaka]

Pa se bo to kaj izboljšalo?
