Hi,

first of all thanks for your great tutorials!

However, with this one (https://www.digitalocean.com/community/tutorials/how-to-use-gmail-or-yahoo-with-php-mail-function) I encounter an issue I could not solve so far.

If I do:
cat sample_email.txt | msmtp –debug -a gmail bob@domain.com

There is a lot of console output, ending with:
reading recipients from the command line

If I wait long enough (approx. 2 minutes) I receive the mail. However, the problem propagates to phps mail function. This means, if a user fills out a contact form he has to wait for approx. 2 minutes until he receives feedback.

(When googling, I usually find that the /etc/hosts file needs to be properly set, however, this is not the issue here).

Any ideas?

Hello,

Probably your SMTP port is closed, you need to make sure that port 587 is open for outgoing TCP connections via your firewall. You also might have to get in touch with DigitalOcean Support and ask them to open the port for you as well.
