Delays in Relayed Emails
Hi,
I have a problem with emails being delayed and it happens randomly.
I am using James 2.2.0. James is setup to be open relay for local servers
within my set of IP addresses. Sometimes when I sent emails to yahoo
address, they receive it instantly. Other times there are delays upto 2
hours. This also happens to other companies' email accounts. There has been
times when the delay goes up to 12 hours.
Is this a setting in James? Or are they actually delays from other servers
because they are trying to detect is this is a valid from email? What type
of settings is suggested to avoid these delays?
Thanks,
Allen Quan

No it doesn't do it explicitly. But once the mail lands in the spam
folder, one could analyze its complete header to infer that Yahoo has
flagged the originating IP as SPAM.
Why would Yahoo do that?

Try also the "spam database lookup" function in http://www.dnsstuff.com.

You can check if the ip is blacklisted by using spambase.org

Do they land in the recepient yahoo user's inbox?
I am facing a problem in which all mails sent from the JAMES relay are
classified as spam.

Re: Changing Subject and Recipient
Posted by Santosh Puranshettiwar <sa...@wirkle.com>.
Normally the mails that get classified as *spam* land into a "Spam" folder.
I am unaware of how this (creating folders) is done in JAMES. But thats
not an option, you can set a header (something like x-spam: true) based
on which the client may classify it as spam. Essentially, the recipient
address SHOULD be kept intact. This is not only neat but will also
obviate redundant user accounts.

Changing Subject and Recipient
Posted by Rudolf Schmidt <we...@gmx.de>.
Hi,
I successfully configured the build in spam filter and was wondering what to
do with the identified spam mails.
My idea is to change the subject of the mail to something like "Spam:" and
additionally I want to change the recipient e.g. from test@mydomain.com to
test_spam@mydomain.com. After that I would deliver them using the transport
processor.
So each user gets another mailaccount for the spammails and may check what
mails where filtered.
What do you thing about that approach?
How can I change the subject of a mail?
How can I change the recipient the way described?
Thanks,
Rudolf

Perhaps there is a network problem between you and Yahoo!, or some other
reason that prevents you from connecting.

Seems to be a connection problem.

That looks alright.

It would appear from context that the server handling mail for qiaojian.net
didn't like the sender being sent from you.

I checked the mailet log and found a lot of messages that are undeliverable.
Errors messages include:
Could not connect to SMTP host: [ip address], port: 25;
nested exception is:
java.net.ConnectException: Connection refused: connect
Exception reading response;
nested exception is:
java.net.SocketTimeoutException: Read timed out
RemoteDelivery: Attempting delivery of Mail1156958242605-3570-to-yahoo.com
to host mx1.mail.yahoo.com. at 67.28.113.73 to addresses
[---------@yahoo.com]
INFO James.Mailet: RemoteDelivery: Exception reading response;
I am sure that some of these emails have correct address. The last example
above is to my yahoo account. After around 20 mins my email does get
delivered.
However there are also a lot of emails address that have the wrong address
w/ domains that are no longer valid. Those keep on retrying until it reaches
25 times. Does these retry cause delays to other emails because of a queue
or something?
>For example, if a remote system is trying to do greylisting, it could lead

In order to prevent delays due to greylisting, can I reduce the delayTimes
to resent the emails in the configuration file? Or is it advised not to
modfiy those times?
> --- Noel
And also
Exception delivering message (Mail1156483577430-20551-to-qiaojian.net) - 452
Invalid sender: [relayed email address]
Does this mean that the email is invalid because it was relayed?
Thanks,
Allen

Check the mailet log for errors sending the e-mail, which would cause JAMES
to reschedule the e-mail for later retries.
For example, if a remote system is trying to do greylisting, it could lead
to delays in delivery.
