Is it possible to configure #Gmail (web client) to send an email “from” an alias on a domain that I own, like alias@example.com, but using Gmail’s own #SMTP server, because I don’t have my own SMTP service for example.com?
Yes, I know that’s ripe for spam abuse. But Gmail docs are not clear on this. And I can verify that I control the alias and the domain.
This is for occasional one-off low-volume sends (eg not ongoing email marketing or newsletter).
Thanks!

@rl_dane @ShinjiLE if you or someone else wants to help argue, the thread is at https://community.letsencrypt.org/t/do-not-remove-tls-client-auth-eku/237427 (Discourse, so JS webbrowser), I’m exhausted.
Loos like the guidance for using #SMTP gateway for #Telemessage is deleted, but Google still retains it in the search result. The links shows general info pages
When Mozilla Thunderbird starts hammering on the CPU cores of your computer you configure it in this way.

... configuration editor. Type idle into the search box, and look for mail.db.idle_limit. According to that bug report, the correct value is 30000000. Check the number of zeros you have; if you only have 300000, that could be causing your CPU problems.

I recently came along this project. I haven't tried it, but this may look like it would solve your problem.

#ActivityPub and #SMTP (Simple Message Transfer Protocol, also knows as e-mail) have more in common than you might think. Both are about accepting or refusing messages on the instance/server level. Both use comparable rulesets. One has 30+ years more of experience. Worth listening to them, IMHO (In My Humble Opinion). I am one of the lucky ones that know both :)
Sempre più arduo…
Illo tempore - ma nemmeno troppi eoni fa - ti installavi postfix o dovecot facevi, due o tre aggiustamenti1 e ti facevi il tuo server di posta (SMTP). Oggi gestirsi il proprio server SMTP è diventato assai arduo!
Ora al grido "per colpa di qualcun o non si fa più credito a nessuno", con l'abuso da parte di chi ti riempie la casella di spazzatura siamo arrivati all'estremo oppo

Gmail Sunsets 3DES Triple Data Encryption: Security Upgrade Impacts Email Senders May 30

Gmail will soon stop support for the 3DES encryption cipher for incoming SMTP

Inbound SMTP DANE (DNS-Based Authentication of Named Entities) is a security protocol designed to secure email communication by ensuring the authenticity of the receiving mail server's encryption certificates when emails are delivered via the Simple Mail Transfer Protocol (SMTP).
By default, SMTP doesn't guarantee encryption, which makes it vulnerable to man-in-the-middle attacks. To secure email communication, SMTP can use STARTTLS, which upgrades a plain text connection to an encrypted one. However, STARTTLS by itself doesn't verify the authenticity of the receiving mail server's certificate, leaving it vulnerable to attacks where a malicious entity might impersonate the server.
DANE addresses this issue by enabling domain owners to publish their mail server’s encryption certificates in DNS records, which are protected by DNSSEC (Domain Name System Security Extensions). This allows sending mail servers to verify the authenticity of the receiving mail server's certificate before establishing an encrypted connection.
When an email is received, the receiving mail server uses DANE to publish its certificate in the DNS, allowing the sending server to check the certificate's validity before establishing a secure TLS connection. This ensures that emails are delivered over an encrypted connection and that the encryption certificate is trustworthy and has not been tampered with.

@Linux for @monocles it's about their mail & messaging solutions which are subscription-financed and in return just work on any devices as well as their nextcloud.
They also offer apps for those, and the #monoclesChat & #monoclesMail #apps can be used with any #XMPP and any #eMail provider that offers #IMAP & #SMTP respectably.
Also they allow for fully anonymous payment using #Monero and #CashByMail.
The ither two I can understand fully...
@delta @madsee34583 AFAIK you could use any mailserver pending it does #IMAP & #SMTP.
Not shure what @monocles / https://mail.monocles.eu has as limits tho.

Just released pingwing v0.0.13
pingwing is a Lisp-powered notification nexus (Guile Scheme) - Programatically send e-mail with HTML (SXML) templates, (and more things coming soon)
https://codeberg.org/jjba23/pingwing
Do you want to work the complexity away of sending e-mail, Slack or other notifications, from every other program? Specially if you use a (micro)service oriented architecture?
