Do you know that we offer great web hosting for your PHP applications? We know PHP/email/DNS and everything related to hosting very well, so you can always ask for technical help, once you become our hosting or web development customer.
We recommend using Gmail for all outgoing mail from your domain. This way your web site's IP address will stay clean and you will never get black listed. Your customers will always receive your communications. Contact us using the form on the right to find out how to do this.
Recently one of our customers reported an issue sending emails to yahoo.com and noted the “retry time not reached for any host after a long failure period” error in the bounced emails. It's likely that the exim database has become corrupt. To fix it we ran these commands:
/usr/sbin/exim_tidydb -t 1d /var/spool/exim reject > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp > /dev/null
