I am using sendmail to relay voicemail messages from Asterisk. I am currently only able to relay to gmail.com recipents.
I have a PTR record setup to point to my static ip address, as mail.mydomain.com ...
I am not getting any bounced messages to the "serveremail" address I specify in Asterisk. I have tested with sending to yahoo, comcast, and gmail, and so far only gmail recipients are getting the e-mails. As I said before, I am not getting any bounce messages.
Sendmail is only used for outgonig messages, as all of my incoming messages are handled elsewhere, with MX records completely separate from anything to do with this IP address.
And how can I watch what sendmail is doing in realtime? I would like to see the responses it gets as it tries to relay to other mail servers.
