Как создать архитектуру B2B-пайплайна, в которой не проверяется лишнее и не теряется нужное

На входе у нас вакансия, на выходе — проверенный контакт в одной из трёх кампаний. Между ними: дубли, таймауты, catch-all, неоднозначные SMTP-ответы и окно, в котором процесс может упасть после передачи контакта, но до сохранения статуса. Показываю, как мы расставили дешёвые и дорогие проверки и почему выбрали at-least-once.

[Перевод] Self-hosted почта на arch linux, postfix, dovecot и let's encrypt

В этой статье я покажу, как настроить свой почтовый сервер для аккаунтов локальных пользователей без веб-морд, docker-ов, телеграм-помоек и LLM-высеров.

#AWS denied my request to use #SES for our community mailing lists. Fine.

Anyone have a recommendation for an #email delivery service for a ~200 member closed mailing list? I've been struggling with deliverability and reputation.

Local-first, keyboard-native terminal email client

"mxr syncs Gmail, Outlook, Microsoft 365, and IMAP accounts into one local mailbox. It keeps your message history in SQLite, builds a local search index, and exposes the same mail controls through a TUI, a pipeable CLI, a web app, MCP, and an agent skill. Attachment names, types, and sizes are local; mxr downloads attachment contents when you open them. Send through Gmail, Outlook, or any SMTP server. …"

Wenn Tests einfach live gehen…

Huch, da ist mir gerade ein Post mit einem simplen Hallo durchgerutscht, weil ich meinen alten Bot zum schnellen Posten umgebaut habe, der bisher noch auf Telegram lief (weil es eine simple API hat).

Aber wie war das mit der digitalen Unabhängigkeit? Die bringt dir nichts, wenn solche Komponenten dann doch noch auf proprietären und leicht zwielichtigen Plattformen laufen.

Jetzt läuft es auf einem der ältesten Protokolle, das ich finden konnte und wunderbar selbst hosten kann: Mail.

Das kann ich von überall weltweit nutzen, nice eigentlich.

Jak przez jedną podatną wtyczkę WordPress ujawniono dziesiątki poświadczeń SMTP?

Czy jedna podatność we wtyczce do WordPressa może doprowadzić do blokady konta Mailgun? Ciekawą historię opisał Austin Ginder, który zaczął otrzymywać wiadomości dotyczące podejrzanej aktywności na koncie Mailgun (usługa do wysyłki tzw. e-maili transakcyjnych). TLDR: Pracownik Mailgun skontaktował się z Austinem w sprawie ostatniej aktywności na koncie, informując o zablokowaniu...

Как один баг в sendmail создал эру спама и привёл к SPF, DKIM и DMARC

Когда в мае 1978 года Гэри Туерк, маркетолог из Digital Equipment Corporation, отправил 400 сотрудникам ARPANET приглашение на презентацию компьютеров DECSYSTEM-20, он не знал, что станет отцом целой индустрии email-маркетинга ненависти к спаму. Несмотря на это, эра спама началась не с Туерка, а с инженерного решения Эрика Оллмана, который пытался соединить три несовместимые сети в одну универсальную систему доставки почты. Под катом расскажу о том, почему sendmail привёл к эпидемии спама и какие механизмы защиты работают в почте сейчас. Читать

#sSMTP - Externen #SMTP-Server für #Systemmails nutzen.

Dieses Mal geht es um den Simple SMTP-Server, mit dem Ihr – statt eines selbst aufgesetzen – einen externen eMail-Server (z.B. bei einem der großen eMail-Postfachanbieter) zum Senden von Systemmails verwenden könnt. So spart Ihr Euch die aufwendige und problematische Einrichtung und letztendlich den Frust, wenn Eure Mails mal wieder nicht auf der Gegenseite angenommen werden.

It took some time, but it's finally working...

go-mail v0.8.0 (release planned in the next few days) will add native NTMLv2 SMTP authentication support (without any 3rd party library dependency).

I couldn't have done this without the absolute fantastic documentation of the cURL project: https://curl.se/rfc/ntlm.html

Thanks @bagder for providing this. It saved me so much time!
