Auch diesmal war die Antwort folgende:
Hi,
Thank you for contacting Yahoo Mail.
We aren't able to guarantee
consistent Inbox delivery for your mail, but we've made appropriate
changes to the IP address(es) in our database. This should help with
delivering mail to the appropriate Yahoo Mail folder. How your
reputation is seen within the industry represents an extremely important
aspect toward achieving consistent Inbox delivery to your recipients.It's important to know that Yahoo Mail users are able to set their own preferences, including marking received email as spam.
For ways to improve your sending reputation, we suggest you review the following articles:
- Ensure uninterrupted SMTP access and prioritized deliverability
- Best practices for bulk mail senders and postmasters for sending to Yahoo Mail
- Yahoo Mail deliverability FAQs
Another option is to register for the Complaint Feedback Loop program.
Yahoo Mail offers a free program to help email senders minimize complaint rates. If you
participate, Yahoo Mail forwards complaints from our users about emails
sent from your organization. For more info, check out our help article
about the Yahoo Complaint Feedback Loop.Our privacy policies prevent us from divulging additional information, which means we're
unable to offer further help for your request.Thank you for your patience.
Regards,
Ich weise darauf hin, dass mittlerweile nur noch "appropriate changes" gemacht werden, ganz zu Beginn der Problematik waren es noch "significant changes". So oder so ist das natürlich alles Quark - die Mails sind nach wie vor in der Queue und deferred.
Nochmal die Checkliste, was Yahoo empfiehlt:
- Opt out users who have marked your email as spam in the past. Enroll in the Yahoo Complaint Feedback Loop program to get that information.
-> Beim CFL-Programm habe ich mich registriert. Die paar Yahoo-Accounts, die Post von meinem Server bekommen, sind entweder mein Testaccount oder persönliche Kontakte der User auf meiner Kiste. Post mit Bezug auf die CFL habe ich noch nicht bekommen.
-
Check your email streams. Use separate IPs and
streams, depending on your email content type. If the IPs you're sending
your presumably valid email from are also sending unsolicited
commercial email, your sending reputation can be impacted.
-> Dürfte bei einem vorwiegend privat genutzten System wohl kaum relevant sein.
- Make sure your emails are DKIM signed. DKIM signature helps Yahoo authenticate that email is safe, secure and from the senders who claim to send it.
-> DKIM ist eingerichtet.
-
Control your email traffic. If you send emails at a
certain rate and suddenly have a spike of activity, you could get
flagged as a compromised sender and marked as spam. Instead, plan your
campaign and spread it out over a period of time.
-> Ich behalte meine Systeme mit Zabbix und tenshi, die auf einem separaten Logsystem laufen, im Blick. Ungewöhnliches Verhalten (hohe CPU- oder Netzauslastung) sollte mir somit eigentlich auffallen.
-
Check your email content. If the subject lines are
not helpful or appear to be generic, users may not be interested and
mark it as spam. When many users mark an email you send as spam, it can
impact your overall deliverability.
-> s.o., vorwiegend private Mails
-
Publish reverse DNS (PTR) records for your sending IPs.
Yahoo is more likely to downgrade an IP’s sending reputation if there
isn't a reverse DNS entry for your IP address. Not having a reverse DNS
entry can cause your mailing IP to look like a dynamically-assigned IP
instead of a static mail server.
-> ist gegeben
Ich habe eben eine Testmail an allaboutspam geschickt, das Ergebnis war, dass meine Mail scheinbar URLs enthält, welche bei URIBL gelistet sind. Sowohl meine IP-Adresse als auch meine Domains sind dort allerdings NICHT gelistet.
Da mir mittlerweile die Optionen ausgehen, werde ich mal bei netcup nachfragen, ob es möglich ist, eine zweite IP-Adresse aus einem _anderen_ Adressbereich zu erhalten. Vielleicht bringt es ja was, die Mails dann darüber zu senden.
MfG Aleph
