DAHI Mailserver

[damg70]

Question: are we running standard "mail" via RedHat? We will probably want to open email ports 143 and 993 for IMAP (regular and secure, respectively).

@damg70 what would we use imap for? We won't have an email server for regular email accounts. THe only thing we need is sendmail that I can think of. What is the use case?

[damg70]

we’d use IMAP if we ever wanted to create dahi-specific email addresses… maybe so, maybe not.

otherwise, sendmail would allow us to send mail via scripts, which is may be necessary for I/O in general.

ok, sorry to be thinck. Do we need both ports open for sendmail? I'll put the request in to ITS once you answer. probly not going to be open this week though.

If we do imap with ssh we'll need both ports open but for now 25 (I think) for sendmail should be fine.

I'm all thumbs over here.

@damg70 , reading up on https://waffle.io/digiah/2do I want to make sure we are not opening up smtp access to world for russian spamfest

@damg70 actually reading up on https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-email-mta-sendmail.html, but try the waffle.io thing too. It is pretty smart.

@damg70 actually all of chapter 17 looks like we need to read it. For now I think we should set up the capability to send mail from the forums, make it so nobody can relay mail (defaults to this I think) and only localhost can send. No incoming mail at all. I'll read up on this, but could you too? For forums, besides simple machines, we might consider bbpress or something similar since we are already in wordpress.

@damg70, it looks like postfix will be better than sendmail for our purposes. It is installed by default.

@damg70, actually maybe we should set up the bb first and see where it fails. postfix might already be configured. I sent the request for port 25 open to outside, but it is not yet open on our firewall.

closing for now. reopen if needed.

25 is open to outside, but we need to open it still on our firewall.
