SSMTP adding

[hellresistor]

Simple way to set mail output using an existing account :)

I also stumpled across ssmtp while i was trying to find a way to send mails without having to set up either exim4 or postfix. However sSMTP is orphaned since March 2019. You might want to checkout msmtp, which works fine for me and is even simpler than sSMTP. The config example for msmtp works like a charm, just be sure to install both msmtp and msmtp-mta.

Thank you! I will explore msmtp!

Igaida and the Issue on ssmtp about special chars (like as # ) on password, exist this issue?

[lgaida]

I don't think so but it may depend on how you edit the config file, e.g manually editing via vi/nano or echoing into the file...

I have it work with passeval and gpg passfile. ;) TY your tip about msmtp! O/ maybe need add this command because psad mail notification ln -s /usr/bin/msmtp /usr/sbin/sendmail

@hellresistor This looks great. My server has been down so I can't test but as soon as it is up I will confirm and then merge. Thanks!

[hellresistor]

As I tested.. using msmtp -v mail@mail.dom need put at least one time the password of keyfile...

Well... resuming this will not so much secure.. since that password has stored on ram.. as your server are located on cloud server.. Otherwise Not matters if you have the physical control :) This its my opinon.. someone correct me if I see wrong way ;)

So I am finally getting time to check this. Just trying to understand, why would something like msmtp be better than exim4?

[imthenachoman]

What happens if the network goes down? Will msmtp queue the messages?

As I know, with msmtp is possible configure any email provider.

Good question, but it suppose do same as sendmail.

[imthenachoman]

From what I am reading, it doesn't look like msmtp will queue the messages. For queuing you need another program.

i have readed this again and not answered it really. Well I cannot say was better... should exim4 better to google services, of sure. But This It is more like an alternative.

Ah. I see what you mean. I will confirm these steps using a VM and then add them in. Thanks!

[hellresistor]
