novice trying to use sendmail for the first time. only issue mails never arrive (not even in spam) I have the following logs:
mail.err is empty
mail.log shows accepted for delivery
but I also get stat=Deferred: Connection timed out with alt4.gmail-smtp-in.l.google.com
sometime but not always so not sure if this could this be the issue ?
I already checked that port 25 is open with netstat -tuplen | grep 25
Mail.log:
