SMTP is not working

@archonic08 thanks for reporting this. May I know which email hosting is this configured for? Which other plugins were you able to use the same settings in? It’s OK to mention the plugin name.

I use regular cpanel hosting. Create an email acc using the same domain and use the smtp setting.

the 2 smtp plugin that’s working with the same setting are fluentsmtp and post smtp.

Having the same issue here. I’m using a Microsoft Exchange account with an application password for SMTP authentication. Works just fine under FluentSMTP, but under ASE with the same settings, the test email just spins endlessly. I’ve left it running for a solid 15 minutes but still nothing, and no debug output in my debug.log either. Attempting to send emails from elsewhere on the site does nothing too.

I’m suspecting STARTTLS, but that’s just a hypothesis.

@archonic08 do you mind sharing which hosting provider company and which hosting package you are seeing this issue on? I may need to diagnose the issue directly on that same environment.

@lulech23 thanks for reporting. This is a known issue with MS Exchange account. I suggest continue using FluentSMTP for now until this is resolved in ASE.

@qriouslad I’m using linux cpanel hosting on verpex.com. Reseller pro plan. I will test this on my other cpanel on different provider and update you the results.

@qriouslad Figured something out. Turns out that if I enable “Force the usage of the sender name/email defined above” I’m able to send over Exchange SMTP. I suspect either $phpmailer->From or $phpmailer->FromName is not being set in some conditions if $smtp_force_from is not enabled.

In my case, it’s no problem to force the sender name/email, so I will go with this for now!

@qriouslad i tested the smtp features on a different cpanel hosting provider and its working fine. So I think it’s hosting specific issue.

@lulech23 thanks for testing further. That is useful debugging info. I’ll be sure to keep this in mind when I have a chance to test with a Microsoft Exchange account.

@archonic08 thanks for testing further. Would be useful if you can figure out what might be different with the reseller pro hosting. Maybe try a different port number and security settings there? Sometimes cpanel hosting provides a couple of routes. e.g. Non-SSL via port 587, and SSL via port 465.

Marking this resolved for now.

Just chiming in to say that I tried the SMTP setup with Google Workspace using their app password (specified here: https://www.wpase.com/documentation/gmail-google-workplace-email-smtp-host-delivery/) and test emails are not being sent and errors aren’t being logged in debug.log. I know that Google depricated “less secure apps” this past summer, and I wonder if that has something to do with it.

I can get emails to send using a cPanel email account. But I sure need to send email via my Google Workspace account.

Thanks.

@blatka apologies for the belated response. Maybe. I’m using @gmail for SMTP and it is working fine. It’s possible Google Workspace has limitations in using an app password. I’ll need to test this when I have the chance.

I am experiencing a failure with Gmail. My site was sending emails fine with fluentSMTP, but when I use the same settings in ASE, I get this in my PHP error log:

@nitrospectide my setup wtih a gmail application password is working well. Perhaps you were authenticating differently in FluentSMTP? Using Application Client ID & Application Client Secret? With ASE, you’ll need to use an app password.

@blatka I just tested with a google workplace email, and the steps outlined in https://www.wpase.com/documentation/gmail-google-workplace-email-smtp-host-delivery/ still works. Please make sure your app password is up to date or new. There’s a chance you’re using an old app password google revoked because you changed your email password at some point. In that case, you need to create a new app password to use in ASE.
