421 cl21.gs01.gridserver.com: Too much load; please try again later

It seems your mail server is too busy to deal with you! What about if you try setting the mail to send by SMTP but to localhost with no authentication? Does that work? Are you on a shared hosting server? Most shared hosting normally have web and mail on the same box, so SMTP to localhost usually works fine.

(I removed your password and obfuscated your email, hopefully you’ll get a little less spam!)

* Use the PHP mail() function to send emails.

Now I don’t seem to be getting any error messages! I sent a couple of test emails and they all worked!

However, I tried registering on my blog with a yahoo email address and I never received the confirmation email with the user password. I tried registering with other email including gmail accounts and the confirmation emails came through.

What’s up with yahoo?

Thanks for working on these problems. I appreciate it very much!

I’m having problems with your plugin. The concept is great, but it doesn’t seem to work. I updated to 0.7 and tested it with a yahoo address and it sent the test email. Then I tried another email address and I got an error. So I tried the yahoo address again, and this time an error came up!

Here’s the output of the error:

Test Message Sent

The result was:

bool(false)

I’ve tried Yahoo and Hotmail emails and neither of them get their confirmation emails, however, the admin email receives the email immediately about a new user registering.

The GMail accounts are also the only ones that receive the test email if I send them out.

Am I just overlooking something here?

Thanks

I think it is a problem with bad webmail like hotmail who cannot manage correctly UTF-8 encoding, I solved it by using the php funtion htmlentities() and evrerything is OK now.

Thanks for your reply.

Any hints on how to work around this?

I would like to upgrade but am extremely hesitant.

I just installed this plug-in today and it seems to be a little flakey when sending out new registration emails. I am running WordPress 2.5 and have no other email plug-ins installed.

My problem is similar to that of Yannick. When I register a user using a gmail account then the administrator receives his email AND the newly registered user receives their email including their password. However, whenever a new user registers using a hotmail or yahoo address, the admin still receives his email fine, BUT the user never receives the email stating their password.

I am not using the SMTP authentication either, as i´m not entirely sure what it is asking for in those two fields.

Is there something else I need to do to enable other accounts to receive their passwords?

Thanks,

I’ve installed WP Mail SMTP, but for some reason it does not work when an email is sent to a hotmail address…

I use STMP without authentification and send out a test email. When I send it to my yahoo account it works fine, but when I send it to my hotmail it doesn’t…ANy ideas on how I could fix this?

Thank you!

I would put here the entire log if that helped..Thanks for the plugin and help!
