Pour laposte, je vois sur le serveur mail qu'il y a eu 2 échecs, et beaucoup d'autres qui n'ont pas été en échecs.. Je n'ai pas réussi à voir pourquoi.

D'après http://www.arobase.org/forums/messages-perdus-avec-poste-net-probleme-smtp-t26706-30.html#p86014 , laposte.net est strict (de façon incorrecte) vis-à-vis du spf..

Problème encore présent :

host smtpz4.laposte.net[194.117.213.1] said: 550 5.5.0
    Service refuse. Veuillez essayer plus tard. service refused, please try
    later. LPN007_510 (in reply to end of DATA command)

chez free.fr

SMTP error from remote mail server after end of data:
    host mx1.free.fr [212.27.48.6]: 550 spam detected

A priori chez free la mention spam detected n'est pas abusée. C'est juste que leur politique antispam (rejet) est plus méchante que la notre (marquage).

Il reste néanmoins des soucis avec la poste :

Nov  3 07:35:20 mail postfix-slow/smtp[26294]: 74E2CED6: to=<bling@laposte.net>, orig_to=<bling@april.org>, relay=smtpz4.laposte.net[194.117.213.1]:25, delay=28, delays=0.02/0/28/0.01, dsn=5.5.0, status=bounced (host smtpz4.laposte.net[194.117.213.1] said: 550 5.5.0 SPF: 62.210.101.52 is not allowed to send mail. LPN007_401 (in reply to MAIL FROM command))

Et avec d'autre. On a du mal à émettre du courriel...

Nov  2 15:14:03 mail postfix-slow/smtp[28566]: C0598113C: to=<bling@live.fr>, orig_to=<bling@april.org>, relay=mx4.hotmail.com[134.170.2.199]:25, delay=94, delays=0.13/92/1.7/0.24, dsn=5.0.0, status=bounced (host mx4.hotmail.com[134.170.2.199] said: 550 SC-001 (BLU004-MC1F20) Unfortunately, messages from 62.210.101.52 weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

En fait ça ne sent pas bon du tout cette affaire.

à tout hasard je rempli ce formulaire https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&locale=en-us&ccsid=636137859226697867

Un exemple d'email qu'on a échoué à transmettre, et qui m'interpelle :

# grep A0804F47 /var/log/mail.info

Nov  3 17:39:03 mail postfix/qmgr[8587]: A0804F47: removed

Ça ressemble méchamment pas à du Ham. Malheureusement, je n'ai vu aucune autre trace qui me permette de voir le message et/ou ses entêtes. Est-ce possible de demander à postfix de ne pas supprimer ces messages ? J'ai l'impression qu'on relaie du spam et que ça niut fortement à notre réputation...

Subject: Reported deliverability problem to Outlook.com SRX1361525224ID

Dear François Poulain 

We have completed reviewing the IP(s) you submitted. The following
table contains the results of our investigation. 

Conditionally mitigated
62.210.101.52
Our investigation has determined that the above IP(s) qualify for
conditional mitigation. These IP(s) have been unblocked, but may be
subject to low daily email limits until they have established a good
reputation.

Please note that mitigating this issue does not guarantee that your
email will be delivered to a user’s inbox.

Ongoing complaints from users will result in removal of the mitigation.

Mitigation may take 24 - 48 hours to replicate completely throughout
our system.

If you feel your issue is not yet resolved, please reply to this email
and one of our support team members will contact you for further
investigation.

Regardless of the deliverability status, Outlook.com recommends that
all senders join two free programs that provide visibility into the
Outlook.com traffic on your sending IP(s), the sending IP reputation
with Outlook.com and the Outlook.com user complaint rates. 

Junk Email Reporting program (JMRP) When an Outlook.com user marks an
email as "junk", senders enrolled in this program get a copy of the
mail forwarded to the email address of their choice. It allows senders
to see which mails are being marked as junk and to identify mail
traffic you did not intend to send. To join, please visit
http://support.msn.com/eform.aspx?productKey=edfsjmrpp&page=support_home
_options_form_byemail&ct=eformts. 

Smart Network Data Services program (SNDS). This program allows you to
monitor the ‘health’ and reputation of your registered IPs by providing
data about traffic such as mail volume and complaint rates seen
originating from your IPs. To register, please visit
http://postmaster.live.com/snds/. 

There is no silver bullet to maintaining or improving good IP
reputation, but these programs help you proactively manage your email
eco-system to help better ensure deliverability to Outlook.com users. 

Thank you, 

Outlook.com Deliverability Support

A priori on n'a plus de soucis avec Hotmail. Youpi :)

Par contre il reste des soucis avec laposte.net.

Dans les logs actuels, du 7 au 17 novembre, on a 18 rejets, ex :

Nov 16 00:11:01 mail postfix-slow/smtp[21928]: C429FC80: to=<xxxxxx@laposte.net>, orig_to=<xxxxxx@april.org>, relay=smtpz4.laposte.net[194.117.213.1]:25, delay=651, delays=590/60/0.08/0, dsn=5.5.0, status=bounced (host smtpz4.laposte.net[194.117.213.1] said: 550 5.5.0 SPF: 62.210.101.52 is not allowed to send mail. LPN007_401 (in reply to MAIL FROM command))

Or coté spf tout semble aller bien.

D'ailleurs, un test à la mimine vers une adresse (@laposte) que je relève est ok.

Donc il faut voir à quoi ressemble ces emails rejetés. Peut être que ces rejets sont légitimes mais que la raison invoqué n'est pas la vrai raison du rejet.
