New problems with sending emails / Nuevos problemas con envio de mails....
Quote from DaviddeArgentina on December 1, 2022, 2:15 amHello everyone,
Having detected problems in sending emails through different servers (Gmail, yahoo, hotmail, etc.) I finally found the problem.
It turns out that when you send emails with attachments, these servers "looks" for the content of ZIP, RAR, 7z and other files.
If inside these files there is something that is com, dll, exe, apk, jar, vbs or other executable files, they automatically block it as "high risk content", and, in the best case, they can return the delivery error message.

Check if you are sending your emails correctly.

Hola a todos,
Habiendo detectado problemas en el envío de mails a traves de distintos servidores (Gmail, yahoo, hotmail, etc) finalmente encontré el problema.
Resulta ser que cuando uno envía mails con archivos adjuntos, estos servidores "miran" el contenido de los archivos ZIP, RAR, 7z y otros.
Si dentro de estos archivos se encuentra algo que sea com, dll, exe, apk, jar, vbs u otros archivos ejecutables, automaticamente lo bloquean por considerarlos como "contenido de alto riesgo", y, en el mejor de los casos, pueden devolver el mensaje de error de entrega.

Verifiquen si están enviando correctamente sus emails.

No, in this case, I didn't check. You can check it yourself and tell us if it was possible to solve the issue in this way.
When there is a password on the archive, antivirus on the server cannot scan for suspicious files and skips the archive. The password for the recipient is simply written in the letter or in the archive itself and in this way any files can be sent, even viruses.

Thank you very much for your answer!
After trying several alternatives, the most convenient that seemed appropriate to me is to save the zip file on my server, instead of attaching it to the email, and leaving it as a link.
Cheers,
