550 in your email client

Post by makenoiz »

phpbb 3.0
I recently switched from one host to another. On the original host we use the local mail function in config. The new host says to use SMTP so we are. Everything is fine except in one thread when we post there we get this


Ran into problems sending Mail. Response: 550 in your email client.

DEBUG MODE
Line : 165
File : smtp.php

However the post does post. This appears to be the only thread having this issue.

Anyone have any ideas?

Thanks in advance.

It's a guess, but is it a popular topic? The mailer might be trying to send out too many e-mails at once, breaching the SMTP server's limits.

In e-mail settings, try lowering the E-mail queue batch size and Purge the cache through the ACP index afterwards. If it doesn't help, I'd ask your host.
