ISP will freeze account for 25+ emails ?

[Parangles]

I want to send non spam newsletters
(Ive read the law: identified sender, unsubscribe opt out etc )
to our travel agencies clients but my home ISP Comcast says they will
freeze the account if I send anything to more than 25 addresses at one time .
How can I get around that ? Even if I send it from a real email address like say:
parangleswhatever@jacarandatravel.com, won't they still go via Comcast
from home where I work, and get me shut down?
I have bulk email software "MailList Controller" can I configure that somehow ?
Thanks !

Might ask Comcast about a business account...
20 mails is a smaller number then 25.....(send in groups of 20)

The best way around that is ask your domain host if they have a SMTP server that operates on a port other than 25 - a common alternate is port 587. These will usually be secure servers requiring authentication.

Thanks- I am going to try going through the website domain using my @.com
address and set the output to a slow rate of say 1 messages every 12 seconds
and see if Comcast wakes up or not. (about 1.5 hrs for 500 msgs)
During setup of the email management software it did a test to port 25
so I guess its using that.
Ezy this trial version only allows one list with a max of 100 'members',
so busting up the list is not an option till I buy the full version for $100.

I'll try sending after I load the lists, and get back to you if the 587 port
alternative doesnt work either.
