SSL Mail server connection times out on send()
- by Jivan
When trying to programmatically send an email from a website of mine, with PHP Pear Mail package with SSL connection, PEAR:Mail replies the following :
Failed to connect to example.blabla.net:PORT
[SMTP: Failed to connect socket: connection timed out (code: -1, response: )]
I looked for similar questions on SO and SF, all the answers asking the OP to test a request on telnet or ssh in command line. So, that is what I did and here is what happens :
$ ssh -l myusername -p PORT example.blablabla.net
_
Here, '_' in the second line means that NOTHING happens. Indefinitely, which seems coherent with the timeout message I had from PEAR:Mail. So PEAR:Mail seems out of cause.
But, what I have to tell you is that yesterday, it just worked. Connection was properly established, mails were properly sent, etc. Just today, it doesn't work anymore and I absolutely don't know why. I restarted Apache (in case an extension was broken), restarted mail services, etc. Still. No effect.
Before yesterday (when it worked) and today (when it doesn't anymore), I just didn't touch the server and did nothing on it, simply because I took a day off to write some blog post!
Have anyone of you encountered similar problem ? The problem seems quite common, judging after some googling, but the solution doesn't.
Thanks for any help !
