Issues with Gmail Delivery

I've got a relatively new ISPConfig 3 server running with the free SSL. Everything was running well until last Thursdayish. At that point email, primarily from Gmail, started to get rejected or rejected and delayed, or just delayed. This is an email sent from someone who got a rejection:

Code:

This is an automatically generated Delivery Status Notification



THIS IS A WARNING MESSAGE ONLY.



YOU DO NOT NEED TO RESEND YOUR MESSAGE.



Delivery to the following recipient has been delayed:



    paul@xxxxxxxx.com



Message will be retried for 2 more day(s)



Technical details of temporary failure:

Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 454 454 4.7.0 TLS not available due to local problem (state 9).

It seems to only be happening from Gmail... any ideas?

We recommend contacting the other email provider this is you
i am not 100% sure but looks like you ssl cert is no good or something is wrong with it

Thanks... I recreated the certificates, creating a class 1 following these instructions: http://www.howtoforge.com/securing-y...-from-startssl. Unfortunately, it doesn't appear to have changed much. Gmail still isn't delivering mail in a timely manner.

But, it does maybe point to an issue on my server.

Something amiss here? (note: myhostname = mydomain.com actually has my domain in it)

I've verified that I can receive mail from Hotmail, Yahoo and just about every other provider EXCEPT Gmail.

Anybody else experience this?

Are there any errors in your mail log (in the /var/log/ directory)?

Falko: No, both logs are empty of errors. /var/log/mail.log just shows regular traffic and /var/log/mail.err doesn't have anything.

However, I ran tail -f /var/log/syslog, then went to Gmail and sent a message and watched the log. This is what came up:

Code:

Thanks Falko!

Stupid typos!

You not the only one that has issues with Gmail. I have been watching this thread for a bit, but I do not have a spelling error.

I am curious, did that fix your issue?
