Do the FutureQuest SMTP servers support ETRN?
Posted on 16 January 2004 08:44 AM

I would like to know whether you support the ETRN standard and are willing to queue incoming SMTP mail on behalf of my network.


FutureQuest's qmail servers do not support ETRN for the following reasons:

1) Security problems
2) Spammers love to hijack ETRN-capable SMTP daemons
3) Inefficient use of bandwidth and storage
4) Inefficient queuing system that can cause backups and/or slow delivery
