SMTP Email no longer working

Hello All,

 

I am no longer able to send email from my internal machines through the SMTP gateway. When attempting a send I'm getting the following error:

 

On a windows box:

Error with connecting server;Server says: 554 comomta-po-02v.sys.comcast.net bizsmtp ESMTP server not available

 

On a linux box using sendmail:

050 ... Connecting to smtp.w14d.comcast.net. port 587 via relay...
050 554 comomta-po-01v.sys.comcast.net bizsmtp ESMTP server not available
050 >>> QUIT

 

I am using the same smtp server that I've used in the past on port 587.

Re: SMTP Email no longer working

Hello,

 

We have been using smtp.w14c.comcast.net on port 25 for our scanner to email out scanned documents using our login credentials that ends in .comcastbiz.net This has worked fine for years, and it stopped working around December 20th. Since then it wont connect. Can you help me?
