Hi all,

Any SMTP and/or Laravel moguls around here?

I'm trying to install a Loops server, but I'm getting the following error in the laravel logs whenever I try to use the registration form (which requires an e-mail to receive a registration code):

[2025-11-01 00:45:57] production.ERROR: Unable to connect with STARTTLS: stream_socket_enable_crypto(): Peer certificate CN=`mysmtpserver.tld' did not match expected CN=`localhost' {"exception":"[object] (Symfony\\Component\\Mailer\\Exception\\TransportException(code: 0): Unable to connect with STARTTLS: stream_socket_enable_crypto(): Peer certificate CN=`mysmtpserver.tld' did not match expected CN=`localhost' at /var/www/loops/vendor/symfony/mailer/Transport/Smtp/Stream/SocketStream.php:171)

The SMTP server (postfix) is installed on the same machine as the Loops website. I'm wondering if that could make things a bit harder.

Any help would be much appreciated.

You might try phpmailer

@Papa Dragon (back on Streams) I don't know anything about Loops, never heard of it until now, but it looks like you missed replacing "localhost" with your actual domain somewhere, or with the domain of your SMTP server.

A bit, yes. Can't you go through your domain provider's SMTP server? It's what I usually do, which has the added benefit that e-mails won't get rejected by the receiving server. Unless you set up a full mail stack with an MX record and are only using addresses on that server...

Edit: Just dumped a stupid question, didn't read right. Better have some coffee first 😁

@Papa Dragon (back on Streams) Also, apparently Laravel caches the configuration, so this cache needs to be cleared after you make changes. Just did a quick web search, maybe this will help:

I only tried php artisan config:clear & php artisan config:cache. I'll try some of the other commands.

@Papa Dragon (back on Streams) One more question; did you test your Postfix setup independently? Do you know for sure that it works?

No. And of course THIS is what isn't working. Until now I've only made sure that emails sent to *@caselibre.fr were well received, but did not check that sending mail through postfix also worked. Turns our it doesn't. Now I just have to figure why.

Thanks!

Yay. Fixed my postfix configuration, or more accurately had it regenerated, and then run a few Laravel commands with the help of the Loops developer and now we're good. Thanks again for the hint @Tanja.

@Papa Dragon (back on Streams) If I had seen your post after coffee, it probably wouldn't have taken me three replies and correction to make that suggestion 😆

Hello

I think the reason for this error is that server name you have in Laravel ”localhost” doesn’t match the name in the tls certificate ”mysmtpserver.tld”. You should call the smtp server in Laravel also with the ”mysmtpserver.tld”.
As the Loops and Postfix is in the same server, you could drop the tls and go without encryption. Then the names don’t don’t matter

The changes in the configuration were not actually loaded, a few Laravel commands were necessary, so it kept trying localhost rather than anything I'd put in the .env file. Now it works :)
