I looked this up and there was a lot of talk around this.
I am using nextcloud-aio
Basic settings trying to set up smtp with gmail
I get
A problem occurred while sending the email. Please revise your settings. (Error: Email could not be sent. Check your mail server log)
I looked into these two posts
here
and here
I added the recommended fix to my config.php like this
## I added these lines
'mail_smtpstreamoptions' =>
array (
'ssl' =>
array (
'allow_self_signed' => true,
'verify_peer' => false,
),
),
## this is the end of the added lines to the config.php
'mail_smtphost' => 'smtp.gmail.com',
'mail_sendmailmode' => 'smtp',
'mail_from_address' => 'my-mail',
'mail_domain' => 'gmail.com',
'mail_smtpport' => '587',
);
Any suggestinos?
