Laravel SMTP mailtrap [Connection timed out #110]

Question

I'm trying to send email with Laravel using mailtrap for testing in a local homestead server.

The firewall shows no rules blocking port 2525.

Mail driver config:

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=$USERNAME
MAIL_PASSWORD=$PASSWORD
MAIL_ENCRYPTION=null

Error returned:

Fatal error: Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host mailtrap.io [Connection timed out #110]'

If you try telnet mailtrap.io 2525 does it work? – Rocky

After fighting with this for hours, I found out that if I change the host to the IPv4 address, it works. – Photoreceptor

So you have a name resolution issue. Note that mailtrap.io is handled by Google for the mail and has 5 MX records. – Rocky

On 8 March 2018 Mailtrap blocked the traffic from “mailtrap.io” Switching to the new host and restarting the system solved the DNS problem. – Photoreceptor

Answer 1

Your hostname is invalid. It should be smtp.mailtrap.io. More info here: https://mailtrap.io/blog/2018-03-09-why-mailtrap-updated-its-smtp-host

P.S. Mailtrap doesn't have static IP addresses, so your way with IPv4 will work not so long amount of time.

This appears to have solved the problem! I'm not sure why before it was returning the same error with a different host name, but I completely restarted the system and it started to function properly again. Thank you! – Photoreceptor

How do you handle this error for the end-user? I mean, how do you catch this error and redirect to another page where the user can either try again or report this issue? – Dorettadorette

Answer 2

Adding to Alexey Vasiliev answer , after you fix the hostname don't forget to clear the cache using the following commands

php artisan config:clear 
php artisan cache:clear
