Cpanel blocking mails?

[ASTRAPI]

Hello

I own a forum and the users are validating using email.

Now that i have many registrations a few users are not getting validation emails and i think that cpanel is blocking them because are many.

What i must check to make the mails unlimited or raise the limit?

Thank you

Hello,

cPanel does not limit emails per hour for scripts sending email using the PHP mail() function or sendmail. Only SMTP authenticated emails are limited. Now, a sender rate per hour for ratelimiting could limit the emails, which would be caused by the person's IP having sent too many emails already. The only way to know for sure what is even happening would be to check the exim logs for the emails that aren't being received:

exigrep [email protected] /var/log/exim_mainlog

Where [email protected] is the email account that is not receiving the email.

If you do not have access to check the exim logs, please contact your hosting provider to ask for assistance.

Thanks!

I have some lines there like:

2011-06-16 02:15:32 1QWzJ5-000G11-OI => panagiotis_pao13 @ windowslive.com R=lookuphost T=remote_smtp H=mx1.hotmail.com [65.55.92.136]

That only looks like you've provided part of the log. Did you use grep rather than exigrep as I indicated? grep isn't sufficient for exim log examination because it only provides part of the log. Please provide the full output from exigrep

I was send you the file by PM as it has many private ip's inside please check it.
