Not really
You need to configure php a little differently for it to work with ssmtp
The default way it calls the mailer does not work with sendmail

Any recommendations for an smtp server?

[Poolkop]

If you jsut want to send mails, ssmtp is perfectly fine
Let me search the correct line to put in php.ini for it to work, just a moment
Sendmail_path = "/usr/sbin/ssmtp -t -i"
That's it :)

[ovigo22]

So I don't need an additional server with ssmtp

ovigo22, i'm using postfix on my servers.

[Poolkop]

You can run it on the same server without problems (ssmtp)
This setup actually expects the ssmtp server to be on the same machine, as it's directly calling the binary

[PaulKolin]

ovigo22, if your provider lets you send mails without authentication to its smtp-servers, yes.

[Poolkop]

PaulKolin, ehmm with ssmtp you are your own smtp-server...
Ssmtp is full smtp server
Just with very little functionality besides sending mail out

[PaulKolin]

Poolkop, but no way to deliver mail to any mailbox.
