Dear Users, maybe someone has been walking along the same road as me and might help:
I ran Postfix 2.7.0 (the package which comes with the Ubuntu Distro 10.04.3) for some time happily, with TLS and dovecot. At the beginning of 2012, I ran into the following problem: Receiving mail was working properly, but when sending via Thunderbird 8, I came across this behaviour: - small emails OK - larger emails with attachment: Thunderbird gives: SMTP-Server DDD.DDD.DDD.DDD Timeout In /var/log/mail.info: postfix/smtpd: lost connection after DATA from AAAA.AAAA.AA [DDD.DDD.DDD.DDD] In /var/log/mail.warn: postfix/smtpd: warning: TLS library problem: 20014:error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac:s3_pkt.c:422 I found this error description on the net: http://readlist.com/lists/postfix.org/postfix-users/16/83463.html My conclusion was that I had to delve into the problem deeply to pinpoint the cause. Before doing this, I believed it to be a good idea to update every package involved (Thunderbird/OpenSSL/Postfix) to the newest version available, so I wouldn't debug something which might already be solved. For Installation of Postfix 2.8.7, I used this: apt-get build-dep postfix apt-get source postfix cd postfix-2.7.0 uupdate ~/Downloads/postfix-2.8.7.tar.gz cd ../postfix-2.8.7 dpkg-buildpackage -us -uc -nc With the dpkg-buildpackage-command, on this line: gcc -Wmissing-prototypes -Wformat -DDEBIAN -DMAX_DYNAMIC_MAPS -DHAS_PCRE -DHAS_LDAP -DMYORIGIN_FROM_FILE -DHAS_CDB -DHAS_MYSQL -I/usr/include/mysql -DHAS_PGSQL -I/usr/include/postgresql -DHAS_SSL -I/usr/include/openssl -DUSE_SASL_AUTH -I/usr/include/sasl -DUSE_CYRUS_SASL -D_USE_TLS -02 -I. -I../../include -DLINUX2 -o master master.o master_conf.o master_ent.o master_sig.o master_avail.o master_spawn.o master_service.o master_status.o master_listen.o master_vars.o master_wakeup.o master_watch.o master_flow.o ../../lib/libglobal.a ../../lib/libutil.a -lssl -lcrypto -lsasl2 -L/home/ubuntu/postfix-2.8.7/debian -ldb -lnsl -lresolv I get these errors: ../../lib/libglobal.a: undefined reference to 'PQresultStatus' ../../lib/libglobal.a: undefined reference to 'PQgetvalue' etcetera etcetera , approximately 30 lines in the same form. I don't know how to fix these errors with libglobal.a, and I don't know as well whether it was a good idea to upgrade at all. Has anyone an idea on how to proceed? Any help is greatly appreciated, Paul
