[TriLUG] sendmail clarification

[Jon Carnes]

There is one particular timeout that you may want to increase.  You can 
increase the amount of time that you will allow for an open connection that 
is not actively talking.  There is an entry in the Sendmail FAQ about this.

Increasing this timeout will help if the noqueue problem is due to an 
overworked Sendmail server which makes the connection to your server, but 
stalls out trying to deliver the data. 

Good Luck!

Jon
