HELP SMTP / Where to find some specific smtp data

Virtualmin
1

Hello!

I have an php application which need 4 different pieces of info to send mail.

SMTP server address
SMTP server port
SMTP username
SMTP password

I am a newbie on setting up server email, for this reason my questions :wink:

Where can I find these for a specific mail address.

SMTP server address: does this need to be an ipp address or domain name?
SMTP server port the firewall only say smtp but no specific portnumber
SMTP username Where can I find this?
SMTP password Where can I find this?

Thanks a lot for your help!

Howdy,

The server address can be an IP address or domain name… what you use doesn’t matter, it simply needs to point at your the correct server.

Regarding the other info – that all depends on what server you plan on using. Do you plan on using your own Virtualmin server? Or were you going to send the email using a remote server, such as an ISP’s mail server?

Hello Eric,
Some updates.
I enabled port 25 in the firewall and even disabled the ufw firewall. (I use 2 firewalls).
But no result. The mail is still not arriving to its destination.
Anyway in the syslog also something is wrong:

It is getting complicated :frowning:
I hope you can make something of these logs…

Thanks in advance Eric!

Howdy,

Hmm, two comments up, you shared your email logs… and in there appears to be a message that was successfully sent to Gmail.

Is it possible that the message ended up in your spam folder at Gmail?

Hello Eric,

Indeed the mails where hidden in the spambox.
I will make a new seperate post for this problem.

Thanks Eric, you are great!
