You're welcome! ;)

All OK now!

"sendmailpath = /mycustom_path/exim -t"

as suggested in the link did it.

Many thanks for your patience '~Z~Man' - you've made an old man very happy! ;)

Well,
since Ossn is not a command line program but based on PHP you have to configure PHP to work with exim correctly - not Ossn.
Please understand that basic server setups like that are beyond the scope of this forum, and I'd recommend to find the necessary information on pages like https://stackoverflow.com/questions/28408777/use-php-mail-function-with-custom-exim-installation instead.

(I'm typeing this post in a text editor, and copying and pasting it into thethread, to avoid getting logged out like I did last time!)
Exim was working OK a while back, but when it was mentioned that there was a SSMPT Component I thought that as it was 'tailor made' for OSSN, it should be the way to go.!

I uninstalled exim4, installed ssmpt and the SSMPT Component (installing ssmpt uninstalls exim and vise versa)

I couldn't get ssmpt working, so I disabled the SSMPT Component and re-installed exim.

Now emailing from the command line works fine, but 'Invite Friends' in OSSN doesn't, so there's a problem with the connection between OSSN and exim. There are no entries in the /var/www/html/error_log

Jim

I give up!

I typed out a detailed description and when I went to post I was logged out and the post wasn't posted!

Many thanks for the help '~Z~Man' and Arsalan.

Hmm, maybe I got something wrong, but 2 weeks ago you said 'it's working fine' ?!?

So: Did you change anything in the meantime?

Anyway, and before too much guessing into the blue ...

• if not already done, enable Error Reporting from your Ossn admin backend (Settings-Basic)
• open the file components/SMTP/ossn_com.php with a simple text editor
• and between line 54 and 55 add the following code

$mail->SMTPDebug = 4;
$mail->Debugoutput = 'error_log';

• save your change, and invite a friend from the frontend
• open the file named error_log in your Ossn root, verify the logged SMTP connection and you'll find what's going wrong

Thanks for the replies Arsalan and 'Z~Man'.

"Alternatively you may use a SMTP component and find some good SMTP provider."

I tried the one 'Z~Man' recommended with both the google and virgin media smtp servers, with no improvement

I'm getting pretty frustrated with this and can hardly believe that I need to set up a full blown email server, just to 'Invite Friends'.

Thanks for the prompt reply, Arsalan.

I looked for a SMTP Component, but couldn't find it in the Components Downloads.

(I really would like to keep setting up email as simple as possible! )

Alternatively you may use a SMTP component and find some good SMTP provider.
