[Deploying Sakai] Making Email Archive work behind load balancer

[Leon Kolchinsky]

Hello,

We have 2 Sakai 2.6.2 servers installed behind hardware load-balancer.
Both of those servers connect to the same DB and have separate serverName
and serverID.
So on each of them "Email Archive" address for site appears as
sitename at serverName.mydomain.com

When I send e-mail to "Email Archive" address that I see on one of those
servers I can see that it's received by James (forwarded by postfix to
James):

Sep  7 12:22:31 vera067 postfix/smtpd[24789]: connect from
cartman.mydomain.com[130.194.13.166]
Sep  7 12:22:32 vera067 postfix/smtpd[24789]: 81E8F5F8E8: client=
cartman.mydomain.com[130.194.13.166]
Sep  7 12:22:32 vera067 postfix/cleanup[24792]: 81E8F5F8E8:

Sep  7 12:22:32 vera067 postfix/smtpd[24789]: disconnect from
cartman.mydomain.com[130.194.13.166]
Sep  7 12:22:34 vera067 postfix/smtp[24793]: 81E8F5F8E8: to=<
newtest at vera067.mydomain.com>, relay=127.0.0.1[127.0.0.1]:8025, delay=2.6,
delays=0.41/0.42/0.5/1.3, dsn=2.0.0, status=sent (250 Message received)
Sep  7 12:22:34 vera067 postfix/qmgr[16731]: 81E8F5F8E8: removed

The problem is that I can't see this e-amil in "Email Archive" section and
it's not being sent to site participants.
All other e-mails (Like e-mail to the newly added users) going out fine from
those servers.

Any idea what's going wrong here and how to fix it?

Cheers,
Leon Kolchinsky
