SMTP-Relay Configuration
The following important configurations should be noted:
- MaxMessageSize=52428800
- This limits the size of messages that the system will accept to 50MB.
- SMTP AUTH
- All TAMU users can configure a single out-going SMTP server,
regardless of being on- or off-campus or their ISPs SMTP servers by
making use of SMTP Authentication (AUTH). The usernames and
passwords are your NetIDs and
respective passwords. As with all areas where NetID use is possible,
the connection MUST be encrypted (the option to use
will be listed as "
TLS" or "STARTTLS").
If your client supports it, please use the alternate MSA port 587.
- Greylisting
- A method used to block spammers using "drive-by" spamming techniques.
For several detailed descripions, please see the Greylisting description page.
- SPF
- We are not yet publishing SPF records, but we are considering
them in the SPAM scoring process.
The following RBLs are in use for blocking problem messages:
- dsn.rfc-ignorant.org
See http://www.rfc-ignorant.org/.
Used to ensure returnability of any message that comes into our
system, only systems that refuse bounce messages are listed since
the senders would not be notified of delivery failures by those
hosts.
- relays.ordb.org
See http://www.ordb.org/faq/.
Reject mail from known abused open-relays.
