Question ISPs SMTP restrictions...

Is there any way to circumvent ISPs SMTP restrictions? In english... Certain ISPs like Videotron do not allow you to use another outbound mail server than theirs to send out mail (SMTP server). They do this to help them manage spam I understand. Great if it does help them for this purpose.

However it's a bit of an irritant for me to constantly have to change SMTP set ups everytime I flip from home (ISP is Videotron) to office or clients' premises (ISP is not Videotron).

Right now Mail.app pops me a message saying that the message could not be sent via the default SMTP server and proposes me an alternative way (pre-programmed in the Preferences>Accounts>Server Setups). Everytime I send an email from home I have to wait for that alert (a few seconds) to come up and choose the Videotron SMTP. Quite irritating and counterproductive.

Of course I could change my default to relais.videotron.ca, but then I would have the problem more frequently at the office or at clients' where videotron is not accepted as a valid SMTP server. Cought in all directions!

So is there a solution to this? My email service hoster (ICDSoft) tells me not. I wonder if others have the same issue and if a brilliant mind has a solution in store.

Many thx.
C.

Some ISPs are not blocking all outbound mail -- just SMTP port 25.

Try adjusting your SMTP settings to use either port 26 or port 587 in place of the standard port 25. This has worked for me at several remote locations where SMTP was blocked.

This won't entirely end the issue, but it should make it relatively painless:

Set up different Locations in your network prefs, with each location's network prefs. You can select your current location from the Apple menu (sixth item) whenever you set up somewhere new.

Unfortunately, this one is a no go. Changed set up, restarted Mail just in case, tried a couple of emails. No success. Videotron still blocks outgoing mail.
Thx anyway!

Does your email provider offer SSL SMTP? If so you might be able to use port 465 (think there's another 587 but I'm not sure on that one - only 465 works for my provider) and use authenticated SMTP with your email username and password.

Or you could use a web mail interface - Videotron offers one.

But you do have access to a valid SMTP server at each location, right? I was suggesting you make that server the default at the respective location (if possible).

So, for example at location "Home", Videotron is used for all outgoing mail regardless of the address (assuming home is where you have Videotron).
