Question

Wordpress email trouble

Hi, guys

My website is not sending emails / notifications anymore.

Can someone give me a hand to just configure my site back to its basic functioning?

There is no connectivity at all. All the ports with no connection.

Thanks!!

hi bobby,

thanks for your reply and suggestions.

but i think otherwise. i guess some bots are using the contact form on one of our client websites to blast them with tons of emails. i think the quick fix is to add a recaptcha in the form. regardless, we will still need to contact the clients for the fix. any idea?

hi bobby,

what if we are hosting tens of wordpress sites for our clients on one of our droplets which we cannot log in to and install an wp smtp plugin?

we still need to fix the php mailer issue, dont we?

from the output of “nc -vz smtp.gmail.com 25”, we got “Connection to smtp.gmail.com 25 port [tcp/smtp] succeeded!” which means at least the droplet is able to communicate over the ports required to send emails externally.

from the output of “tail -20 /var/log/mail.log” below, we got some deferred emails sent from some of our clients. will those deferred emails prevent the droplet from sending other emails? any idea?

Hi, friend

After rebooting there were 52 packages to be updated. I did the upgrade. Then the connection with portquiz was ok. There was no need to trace the route. Then i activated the plugin Post Smpt and the website’s mailing system is normalized.

I thank you guys so much for caring, @Kdimitrov

OMMMMMMMMMMM

I allowed ports 25 and 587 for smtp via putty, but still the connectivity test is giving me a negative result.
