That pretty much tells you what you need to know: you're trying to do
POP3 mail and the connection to the server is timing out.

Error messages can be useful: sometimes a cigar is just a cigar.

thank you for your prompt reply :)

i'm still confused about missing javabean activation.jar file???

i'm quite sure it is not installed on my machine.

have no idea what package to download and where from??

i'm probably just tired, or it is a really bad day. it took me 2 hours to find Javabeans activation framework download at Sun.com.

I found it. it works.

Only, help file doesn't want to check gmail account with the same error that i allready posted.

Any hints?? Or experiences with other free mail services?

whats the default timeout?

maybe try increasing it.

if its still not getting anywhere i would try to manually telnet to the POP3 server and see if it responds, then if that appears to work but the java code doesnt then use a network monitor to see whats happening on the wire, e.g. wireshark :

http://www.wireshark.org/

Are you trying the code from within max or from your development setup?

hmmmmm.

as i said, i'm a complete novice when it comes to java.

i managed to check mail on small local server, but couldn't do it on gmail.

i checked it on max. i have no idea where to change timeout settings. i checked net.mail.recv code, but don't remember seeing anything that looked like timeout value.

thanx for your help

right, i think the problem is that pop3 access to google mail requires SSL, if you look here for details :

this page is a bit easier to read :

I havent used the max net.mail classes so I dont know how much it exposes of the underlying mail library, but hopefully you can set the right configuration.

Hello,
A while ago I created a mxj program to email mp3s of performances as attachments to gmails. I've attached everything. Let me know if you have suggestions or comments.

note - you need to 1.) start pop3 support in your gmail account settings 2.) get activation.jar and mail.jar, and put them in your mxj classpath, and edit the config file so it loads the jars
to get this to work
