SMTP Versand - Fehlermeldung Swiftmailer - T-Online

[monachus]

Hallo Zusammen,

ich verwende bei Contao aus diversen Gründen das Versenden per SMTP.

Bisher funktioniert es ohne Probleme, nun wurde der Zufgang aber seitens T-Online umgestellt auf securesmpt.
Die Einstellungen habe ich nach Vorgabe T-Online gemacht und die Funktionieren auf Outlook völlig problemlos.

Habe auch verschieden Einstellungen SLL/TLS oder Ports probiert, aber es geht keine Mail mehr per SMTP durch.

Contao Open Source CMS 2.9.5-cca-soa-hotfix2 (Umstellung auf aktuelle 3.4 ist in Arbeit)

Seitdem kommt beim Versenden eines Kontaktformulars Fehlermeldungen:

Hat jemand eine Idee, woran das Liegen könnte?

Verwendest eine email Adresse wie outlook.com oder sonst ein riesen Provider?

Eventuell haben die gleichzeitig mit der Umstellung auf ssl auch die Blacklist angepasst. Wenn Deine Domain auf einer Blacklist gelandet ist dann wir die Mail auch nicht versendet. Vielleicht erzeugst Du damit das Time Out?
