Hi ,

I am using monit version 5.5 on fedora 8. It sent alerts to my gmail successfully. I aimed it send alerts to my yahoo  as well as gmail. But it could not .

Bellow I mentioned some details .

---------------------------------------------------------------------------------

UNAME Output:

---------------------------------------------------------------------------------

Yahoo smtp server  configurations are :
---------------------------------------------------------------------------------
set mailserver smtp.mail.yahoo.com port 587
    username "myUser" password "myPass"
    using tlsv1
set alert address@hidden    on { resource }

This is unlikely to work on port 587, since monit (AFAIK) won't send STARTTLS to initiate the TLS session.
It might work without tlsv1 if the server supports non-encrypted sessions.

---------------------------------------------------------------------------------
Debug Output:
---------------------------------------------------------------------------------

Resource limit succeeded notification is sent to address@hidden
Sendmail error: 500 5.5.1 Invalid command

Trying to talk TLS to a plaintext session.

I telnet on both smtp server and I found some differences :

------------------------------------------------------
>> telnet smtp.mail.yahoo.com 587
------------------------------------------------------
Trying 98.138.105.21...
Connected to smtp.mail.yahoo.com.
Escape character is '^]'.

250-PIPELINING

250-8 BITMIME
250 AUTH PLAIN LOGIN XYMCOOKIE

OK, this will probably work without the tlsv1 tag.

-------------------------------------------------------

I think google requires STARTTLS before AUTH, so can't use this port with monit.

-------------------------------------------------------------------------
I tried an other port with following configurations.
-------------------------------------------------------------------------
set mailserver smtp.mail.yahoo.com port 465
    username "myUser" password "myPass"
    using tlsv1
set alert address@hidden    on { resource }

-----------------------------------------------------------------------
I run it at debug mode and the outputs are:
-----------------------------------------------------------------------
Resource limit succeeded notification is sent to address@hidden
Sendmail: error receiving data from the mailserver 'smtp.mail.yahoo.com' -- Resource temporarily unavailable

Looks as if Yahoo declined the mail from your IP address.  Maybe they'll accept it later.  Monit appears to be working correctly.

----------------------------------------------------
>> telnet smtp.mail.yahoo.com 465
----------------------------------------------------
Trying 98.139.211.125...

You can't test a tls session with telnet.  Try openssl s_client -connect smtp.mail.yahoo.com:465
