Hello, I have courier-mta running on my GNU/Linux box with esmtp, pop, and imap running fine. I decided to statup smtps, imaps and pops as well but have run into problems.

the smtps, imaps and pops daemons seem to be running properly :

# netstat -an

Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN tcp 0 0 172.16.31.16:143 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN

pop responds properly :

# telnet 172.16.31.16 110 Trying 172.16.31.16... Connected to foo.bar.com (172.16.31.16). Escape character is '^]'. +OK Hello there. USER foouser +OK Password required. PASS barpass +OK logged in. ^] telnet> c Connection closed.

imap responds properly :

smtp responds properly :

# telnet 172.16.31.16 25 Trying 172.16.31.16... Connected to foo.bar.com (172.16.31.16). Escape character is '^]'. 220 foo ESMTP HELO foo.bar.com 250 foo Ok. mail from: <drz...@foo.bar.com> 250 Ok. rcpt to: <drz...@foo.bar.com> 250 Ok. data 354 Ok. testing

drzook is a legitimate use and has a maildir and can send and receive mail properly.

But this is what happens when i test smtps, imaps and pops :

# openssl s_client -connect 172.16.31.16:465 CONNECTED(00000003) write:errno=104

# openssl s_client -connect 172.16.31.16:993 CONNECTED(00000003) write:errno=104

# openssl s_client -connect 172.16.31.16:995 CONNECTED(00000003) write:errno=104

i've noticed a few strange things :

my /usr/lib/courier/etc/esmtpd.cnf refers to RANDFILE = /usr/lib/courier/share/esmtpd.rnd which exists

-rw------- 1 root root 1.0K Sep 7 19:11 esmtpd.rnd

and i use :

# mkesmtpdcert

to generate my certificate in /usr/lib/courier/share/esmtpd.pem which is owned by daemon(which is the user with which i start courier) and has permissions

-rw------- 1 daemon root 2.2K Sep 7 19:11 esmtpd.pem

however my /usr/lib/courier/etc/imapd.cnf refers to RANDFILE = /usr/lib/courier/share/imapd.rnd which did not exist by default so i changed that to RANDFILE = /usr/lib/courier/share/esmtpd.rnd in imapd.cnf

also,

my /usr/lib/courier/etc/pop3d.cnf refers to RANDFILE = /usr/lib/courier/share/pop3d.rnd which did not exist by default so i changed that to RANDFILE = /usr/lib/courier/share/esmtpd.rnd in pop3d.cnf as well

then i did

# mkimapdcert

# mkpop3dcert

and i got in /usr/lib/courier/share/ :

-rw------- 1 daemon root 2.2K Sep 7 19:11 imapd.pem

and

-rw------- 1 daemon root 2.2K Sep 7 19:11 pop3d.pem

So my question is how to get rid of the CONNECTED(00000003) write:errno=104 error and make smtps, pop3s, and imaps work.

If any further information is required please let me know. Also, is there a command to list all of courier mta's variables at once - i can then post them.

Thanks!!!
