Email setup using port 465 does not work

[murugappan]

Espocrm Versions: 7.2.7 (php 7.4) to 7.4.4 (php 8.1)

Description of problem:

I set up the smtp configuration for the Outbound emails and personal/group email with SMTP port as 465 (TLS) gives error 0 as follows (from the logs):

Version: 7.4.4
[2023-05-10 12:17:47] ERROR: Email sending error: Could not read from sysdev.emastpa.com.my
[2023-05-10 12:17:47] WARNING: Email sending:Unknown error.; 0


Version: 7.2.7
[2023-05-10 09:56:02] ERROR: Email sending error: Could not read from staging.emastpa.com.my [] []
[2023-05-10 09:56:02] WARNING: Email sending:Unknown error.; 0 [] []

But no problems occurs when i set the SMTP port to 587 (TLS).

I use SSL on 465 and it works fine.

yuri thank you. I restest with my own utility program and i found that it was our hosting provided. They are recommending I use port 587 which i do not agree as it is a non-SSL port. Anyway, its not a espocrm problem. Please consider this post as closed.
