Hi,
I'm planing to split cyrus 2.2.13 from my incoming mail server running
sendmail 8.14.3. Basically I set up an openvpn tunnel between the boxes
and changed the CYRUSV2_MAILER_ARGS from FILE to TCP in the cyrusv2.m4
macro on sendmail side and activated lmtp in the cyrus.conf on the other
side. First tests are running fine. Did I forget something? Any tuning
hints?
Seems fine to me, but you may want to allow more than 20 childrens for
LMTP process. If you receive a lot of mails at once, your load will
increase on the sendmail server because you don't have enough lmtp
processes. Actually I use lmtpproxy since I have a murder setup, but
with prefork=20 maxchild=0.
Sendmail will reject connections anyway if the load or connection rate
is too high.
The openvpn seems overkill to me, as mail will often travel in clear anyway.
Also, your smtp server won't know if the mailbox is really available, so
you may have useless bounces (over quota...). You may want to check
