After upgrading ssmtp, two problems occurred: 1. The user did not have permission to use /usr/sbin/ssmtp (through /usr/sbin/sendmail). 2. When permissions were set manually (chmod o+rx) the executable reported that it could not connect to mailhub on port 25. The log entry said: Sep 25 12:09:22 servername sSMTP[6522]: /etc/ssmtp/ssmtp.conf not found Sep 25 12:09:22 servername sSMTP[6522]: Unable to locate mailhub Sep 25 12:09:22 servername sSMTP[6522]: Cannot open mailhub:25 So - ssmtp can not find its own configuration file. This file is in place and correct as far as I know. Reproducible: Always This seemed like a configuration error or a bug. The problem was resolved by downgrading to ssmtp 2.61-r2.
Please post your `emerge --info' and the output of `ls -l /etc/ssmtp' too.
* Starting with =mail-mta/ssmtp-2.62 all users who should be able * to send mails using ssmtp must be added to the ssmtp group. * * See bug #187841 for reference.
(In reply to comment #2) Well, that sounds like it will be really impractical. However, after adding myself to the ssmtp group it is still not possible to send email using ssmtp: send-mail: 501 Bad address syntax Can't send mail: sendmail process failed with error code 1 So, regardless, I'll supply some info here.
