Office 365 as a SMTP server issues

granttransition · Nov 6th 2019

Hi,

I am experiencing issues using Office 365 as a SMTP server. I'm aware that the `PERCH_EMAIL_FROM` and `PERCH_EMAIL_USERNAME` need to match, which they do, here is my settings minus sensitive information.

HTML: SMTP Info

define('PERCH_EMAIL_FROM', '######');
define('PERCH_EMAIL_FROM_NAME', 'The Dudley Arms');
define('PERCH_EMAIL_METHOD', 'smtp');
define('PERCH_EMAIL_HOST', 'smtp.office365.com');
define('PERCH_EMAIL_AUTH', true);
define('PERCH_EMAIL_SECURE', 'tls');
define('PERCH_EMAIL_PORT', 587);
define('PERCH_EMAIL_USERNAME', '######');
define('PERCH_EMAIL_PASSWORD', '######');

Email settings are correct as I can log into their email.

Do perch forms use TLS 1.2 or above? I'm lead to believe it won’t work with anything lower – that could possibly be the issue depending how Perch is programmed to connect to SMTP server?

Thanks

Have you tried define('PERCH_EMAIL_SECURE', 'STARTTLS');

That's what I've got in my 365 settings.

Thanks for the suggestion. Unfortunitly I got the same result. 504 Gateway Time-out

A gateway time-out would suggest that the two servers aren't talking. Is the host blocking the 587 port? Perhaps try 465 with SSL or contact the host to see if they have a special SMTP relay account for you to use.

Thanks Ellimondo, I'll contact them

I also have had a host in the past that blocked connections to external smtp servers at large.
