    Hi,

    A client using my server for emails is having issues sending emails to a client using your service. The errors are:

     

    Connection timed out H=cluster1.eu.messagelabs.com [195.245.230.83]

    SMTP error from remote mail server after RCPT TO:<stook@tektura.com>: 421 Service Temporarily Unavailable

     

    Can you see if our IP or their ISP IP has been temporarily blacklisted or why their emails are not getting through please??
    server address is 91.146.110.198. 

    the sender address is as follows:
    246.12-30-62.static.virginmediabusiness.co.uk
    Sender IP: 62.30.12.246

    If it is temporary like your error sugests how long will it take to heal itself?
    Thanks in advance for any help/advice it would be much appreciated.

    Kind Regards

    Mark

    Hi

     

    I've checked the IPs mentioned and the only one that had any issues was the 91.146.110.198 address which was being throttled by our service.

     

    I've now removed the throttling so you shouldn't see this issue any further.

     

    Thank you
