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...).

lmtp over tcp configuation
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? /etc/mail/sendmail.mc: [...] dnl # Default Mailer setup MAILER_DEFINITIONS define(`confLOCAL_MAILER', `cyrusv2')dnl MAILER(`local')dnl MAILER(`smtp')dnl MAILER(`cyrusv2')dnl /usr/share/sendmail/cf/mailer/cyrusv2.m4: [...] ifdef(`CYRUSV2_MAILER_ARGS',, `define(`CYRUSV2_MAILER_ARGS', `TCP [192.168.100.2] 2003')') [...] /etc/cyrus.conf: [...] lmtpcmd="lmtpd -a" listen="192.168.200.1:lmtp" prefork=0 maxchild=20 lmtpunixcmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20 [...] System Ubuntu 10.04 LTS with sendmail8.14.3-9.1ubuntu1 cyrus-common-2.22.2.13-19squeeze3build0.10.04.1 Cheers Marcus Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus

lmtp over tcp sockets, access denied and lmtp error: Message contains invalid header
Hi, I'm trying to configure postfix to deliver to my cyrus lmtpd. I read the LMTP readme and configured my cyrus like this: lmtp cmd="lmtpd -a -C /mail/mail2/etc/imapd.conf" listen="host.name.tld:lmtp" prefork=10 hosts.deny says to deny all lmtp access, and hosts.allow accepts all lmtp access from one host (that is running the postfix mail server). Now postfix complains: Jul 21 15:25:42 oliebol postfix/qmgr[7484]: 2A9BA7458: from=<[EMAIL PROTECTED]>, size=348, nrcpt=1 (queue active) Jul 21 15:25:42 oliebol postfix/lmtp[7490]: 2A9BA7458: to=<[EMAIL PROTECTED]>, relay=none, delay=4236, status=deferred (connect to mail2.ugent.be[157.193.71.18]: Connection refused) I want to test my lmtp setup, but this fails too: oliebol:/etc/postfix# telnet mail2.ugent.be 2003 Trying 157.193.71.18...

I should of probably looked in the man pages for that one. I was planning on securing it by having a seperate private interface to transfer from the smtp server to imap server. This way it won't add to the imap traffic from clients.
