Does anyone in the #FOSS dev community know whether there is a project to add #Mailgun #API support to the #Joomla CMS #email system?

We need true API submission, not #SMTP connections from the host.

Unfortunately Joomla's documentation around plugins is sparse and none is available for how to build plugins for the mailer system, but an experienced Joomla extension dev may have enough broad familiarity to know where to hook in.

Free m'a bloqué les ports #IMAP et #SMTP, et refuse de les réouvrir. Je vous raconte.

Je fais un peu de #autohébergement sur mon serveur, et derniièrement, j'y ai installé #docker-mailserver

je configure #thunderbird , tout fonctionne nickel, et au bout d'un moment, impossible d'envoyer des emails ou d'en recevoir
Il se trouve que #Free a bloqué le port 25
En 5G par contre, pas de probléme

Et le support a rejeté ma demande

Please #retoot en espérant atteindre quelqu'un de Free 🙏

PostfixとAmazon SES間の通信にSMTPではなくAWS API(HTTPS)を利用してメールを送信してみました

How much of a hit would the trustability and sending reliability of my #mailserver take if I change the just the domain, but not the IP etc ?

For a brief moment in time, #mutt was the perfect #email program for me, I had it configured just right, it really took email work off my hands. I tried it again many years ago, maybe with mutt-ng, but I remember configuring it was a nightmare, especially with several #IMAP servers, using different #SMTP.s for different accounts, automatically detecting and switching sender addresses, etc.
Any chance anyone has a suggestion how I should approach this to substitute Thunderbird at least partly?

I have a suspicion that in a very small way I might have recently contributed towards a minor unshittification of Meta.

I was drawn into it as an SMTP problem.

I can only apologize to the world if it actually does end up making #Meta capable of sending e-mail once more. (-:

As a #qmail user of many years, who did similar work of my own for OS/2, and who was drowned with UBM to the point of just giving up on SMTP e-mail in the 2000s; I can heartily recommend the rejection of Relay clients that do not adhere to the SMTP.

Gresham's Law trumps Postel's Principle.

#tfw You have to email a government agency, explain in excruciating detail why your mail server (and any other that enforces #DMARC) can't receive certain emails they're sending that fail their DMARC policy, and then cross your fingers and pray that the tier 1 customer service rep who reads your email forwards it to someone who can fix the problem AND said someone actually takes the time to do it. *sigh*

It's funny how excellent #blocking login-attempt bots works. I use a simple script to grab #failed #login attempts for #ssh and #smtp and block them for a number days. At first, the number of blocked IP's was in two digit numbers, now it's down to single digit numbers.

@lukasp @Lioh well, that deoends on what you want to use.

@monocles offers two options:

#Chat (#XMPP) & #eMail (#IMAP+#SMTP) and another one with @nextcloud and #Mastodon included.

Oh wow, this not only breaks #SMTP and #XMPP but also #domains (as in, registrars): Fedi thread from https://glauca.space/@q/114641860799614248 and especially the third post down, with the alt-text-less screenshot (I’ll reply there crosslinking here and put alt text in)

Configure IMAP, SMTP or msmtp, set up multiple accounts - this tutorial has you covered.
