I have add a support of simple aliases to ssmtp. Substitution occur when sending "RCPT TO" to server, but before all other substitutions (UID checking, appending domain etc.). It means if I remap "eugene" to "root", message will be sent to address, specified if "root" option in ssmtp.conf. Look at this patch:

I am having a problem rewriting local addresses. I thought all I needed was:

/etc/ssmtp/ssmtp.conf:
Code:
root=me@yahoo.com

to make something like this work:

mail -v -s "ssmtp test" root

But it doesn't rewrite the envelope, which I think is what I need. Here is debug:
Code:
Lestat bin# mail -v -s "ssmtp test" root
.
Cc:

Note the RCPT gets rewritten, but not the "To:"
Any ideas?

I'm having similar issues to this, anybody know how to go about sending local mail?

Code:

sokar:~% echo 'hi' | mailx -s 'test' gavin@localhost
send-mail: RCPT TO:<gavin@localhost> (553 Invalid address syntax)
Can't send mail: sendmail process failed with error code 1


I've ssmtp set up and configured, and I think mailx is using that instead and thus trying all the isp server stuff (which should be unneeded for local addresses). Sending remote email is working fine, though..

I have found only one solution for this: adding aliases support to ssmtp. Otherwise ssmtp will try to send all messages for local users with uid>999 to username@hostname, where "username" is name, cpecified in mail/mailx command line. Try to apply my patch (see above) and write such aliases:
Code:

# /etc/ssmtp/aliases

gavin@localhost: your_account@domail
gavin: your_account@domain

Or just:
Code:

# /etc/ssmtp/aliases
# "hostname" parameter from ssmtp.conf will be used as domain

gavin@localhost: your_account
gavin: your_account

ok after about 3h of emerging and configuring i finally got ssmtp working (nice guide btw) to send mail through my gmail account. but now i have a question

Sudo sends mail to email address root by default and because this mail address (hopefully or else someone is going to have a good laugh at gmail) doesn't exists it goes nowhere. I found out if you put Defaults mailto=user@email.somewhere into /etc/sudoers file sudo sends it to that email address. But now i'm wondering if you could set ssmtp that way if user sends mail to root (for example sendmail root ... bla bla bla ctrl+d) it would get redirected to user@email.somewhere. Is that possible?

That's what the useflag mailwrapper is used to:

OK, just call me a bone head. If I emerge this, how would I tell Postfix to use this.
I just changed my provider, and they use SSL SMTP servers, so I figured I would use gmails.
Thanks

I installed AsphyX's patch (thanks for the good work, btw) but found that Google still wasn't delivering my mail addressed to a local user because though the "RCPT TO:" line was correctly remapped from the local username to the gmail alias, the "To: " line in the DATA section was not remapped and still read "root", for example. I modified ssmtp.c further to perform the same aliasing in the To: line of the DATA section, and now it works great.

Has this been submitted for inclusion into the sSMTP ebuild? In the meantime, maybe we can create an overlay package?

Hi folks,

I've been going nuts trying to get ssmtp to work.

Well, after spending several hours reading the forums on ssmtp, I finally realized that I HAD NOT emerged mailwrapper.

DUH!!

Hope this helps someone.

Sincerely,

Don James

I modified AsphyX's patch so that it supports more than one level of aliasing (you can now alias postmaster: root, and root: myemail@gmail.com) (it's now recursive ^_^). I also changed it to use the aliases file installed by mailbase.

Thank you very much. This was a very useful tip.

btw-My error was not changing:

Code:
UseTLS=YES

to

Code:
UseSTARTTLS=YES

The latter is correct (for my particular gmail circumstance)
