[Clug-tech] sendmail

[Shawn Grover]

Not sure if it applies here, but... I recall some ISPs (such as Telus) 
were blocking port 25 from residential lines.  If you have a business 
package, this should be a non-issue.  But...  I believe if they are 
blocking port 25, they have another port open for a similar purpose (553 
comes to mind but is probably wrong - I need sleep).  I believe that 
port requires you to use authentication though (better in the long run 
anyways...)  Hmm... come to think of it, I believe this is a mail CLIENT 
issue, not a server issue....

If this *is* the issue you are facing, check the archives for this list 
- it's come up once or twice in the past.  But I'm sure someone more 
knowledgeable will pipe up... (Gustin ???? lol)
