Is it possible to do TLS smtp auth with key pair and no passwd similar to ssh login?
location: ubuntuforums.com - date: April 2, 2015
Sorry I incorrectly posted to the chat forum, I hope this is the correct forum...
I'm trying to setup smtp auth with TLS (postfix smtp).
In the same way that ssh login can be performed strictly via key pairs without password login, I was hoping to do the same with smtp auth so that I get the additional security. I've had some trouble with smtp auth hacking and spammers getting relay access.
I know that postfix can be configured to require a certificate, but does that mean that it supports something similar to ssh? Would an email client support a key file, just like putty does for ssh and then used to gain relay access?

[SSL/TLS] Error connecting to secure SMTP server
location: linuxquestions.com - date: September 16, 2014
I know this is a Linux forum, but I don't really know where else to ask for security-related issues.
I'm trying to send e-mails from an old Windows application and connect to a secure SMTP.
When connecting, the client fails with the following error message:

fetchmail and postfix <cr><lf>.<cr><lf> problem
- date: May 30, 2012
Hello to everyone
I have a server running ubuntu 9.10 and set up a mail system with fetchmail 6.3.9 and posftix 2.6.5
On some occasions there's apparently a <CR><LF>.<CR><LF> in the middle of the message body so the mail won't be downloaded completely.
Fetchmail seems to be downloading the mail correctly but when passing it to postfix to be stored in the corresponding mailbox it detects the premature <CR><LF>.<CR><LF> and the message gets stripped.
Here are some fetchmail logs if that helps (although they seem good to me):
fetchmail: POP3> LIST 12
fetchmail: POP3< +OK 12 634630
fetchmail: POP3> TOP 12 99999999
fetchmail: POP3< +OK
fetchmail: reading message [email protected]
:12 of 12 (634630 octets)
fetchmail: Trying to connect to XXX.XXX.XXX.XXX/25...connected.
fetchmail: SMTP< 220 xxxx.xxxxxxx.xxx ESMTP Postfix
fetchmail: SMTP> EHLO C-023-srv
fetchmail: SMTP< 250-xxxx.xxxxxxxx.xxx

I just solved it in two tries. This is what i was telling you that installation is the main problem but you were emphasizing on coding. How can i do the coding with out installation. It was a universal problem because i did not get its solution on other forums. I tried at different forums. They must be located at different parts of the world. That's why i claimed that it has become a universal problem. By this i mean i do not get its solution on the planet earth. Some people on this forum said that they solved this problem. But i believe that they are not human beings. They are from space. If they say that they solved it in 30minutes, they are wrong. They actually solved it in 30 light years. I have now become the first human being who has come very close to its solution.Thanks for your congratulations on this. You are really a man of great calibre. That's why you have over 15000 posts. But you back off often. I would like to remind you again about your Golden rule you set for me.
[SOLVED] Postfix vs Google SMTP servers inconsistency
location: linuxquestions.com - date: August 9, 2014
I want to host my own mail server and in order to do so I've installed Postfix 2.7.0 and Dovecot 1.2.9 on Ubuntu Server 10.04.
One big problem I face right now is that Google SMTP servers reject my mail ONLY WHEN it is being sent remotely. Strange, right?
So if I telnet localhost 25, then issue AUTH LOGIN (not an open relay of course) then send the mail I get a status = sent and I actually receive the mail message in my Gmail's account Inbox. Works like a charm.
On the other hand, if I want to send the mail from a remote host, I use:
TLS issue when sending to gmail through JavaMail
location: linuxexchange.com - date: February 3, 2012
Turns out that JavaMail is a bit more frustrating than I thought it would be. I've looked at several examples online on how to send a simple SMTP email through Gmail's servers (but not through SSL). After trying several different examples of code, I keep concluding to the same example exception when I call transport.connect(). I keep getting this stack trace:
Exception in thread "main" com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. l10sm302158wfk.21
Can someone please tell me what I should add or do to fix this?

clamav & postfix problem on debian wheezy
location: linuxquestions.com - date: April 6, 2015
I'm running Clamav .98.6 and Postfix 2.9.6-2 on debian wheezy.
I've noticed ( I think since the last update ) a permissions problem in my logs.
postfix/cleanup: warning: connect to Milter service unix:/clamav/clamav-milter.ctl: Permission denied
If I increase the permissions of clamav-milter.ctl to 0777 it works but something is changing the permissions back again.
Anyone else got the problem and a solution.
