How delete 'Other SMTP Servers' from email account?

Question

In trying to figure out how to SEND email using my iPhone 3G I changed some port settings, according to Comcast. In the end doing this added a bunch of 'Other SMTP Servers.' I've deleted one of my email accounts and re-set it up, to no avail. The INCOMING port number keeps setting up its own number and I cannot change it to 110, as it should be, so I cannot receive email on theis account. Everytime I change it to 110 it automatically changes itself back to other numbers (587, 99?) when I exit and try to retrieve email. I've synced my iPhone with my pc...didn't work.
So, I need to know how to change my INCOMING port setting to 110 and keep it that way, delete multiple 'Other SMTP Servers' listed within any of my email accounts, and also how do I SEND email while outside the home (I can send email fine when I'm home using my wireless router)?

Same problem. Every time I add a new account its smtp server details are added to the list of available servers, even if exactly the same details already exist in the list. I now have three identical smtp servers listed.
Discovered this when having smtp connection refused problems after adding three different email domain addresses that I use with the same service provider - the first one is ok, the other two always fail smtp connection. The smtp details for all accounts are exactly the same, which works perfectly well when using Mail on my MacPro machine, but not it appears on my iPhone.
I can delete the troublesome accounts on my iPhone (have not yet figured out why all three work fine together on my MacPro machine but not on the iPhone) but, there does not seem to be a way of deleting duplicated or unwanted smtp information from the iPhone. Regarding ports, I use port 25 for sending on all 3 accounts, but I did notice that the iPhone setup automatically chose 587, which although legit does not appear to work.
Any suggestions?
