Bell Syspatico high speed three months free?

Sympatico的问题还是比较多。总体感觉不如Rogers.
1. 合用internet要设置router...,而Rogers则不用。
2. 常常断，我刚用两天，没什么发言权，但是其他不少朋友也都反映这个问题 （断了之后要拔插modem电源等等，搞不懂，反正很不方便，但是Rogers中断极少）
3. Sympatico关闭了Port 25，不允许使用除Sympatico以外的任何其他SMTP邮件服务。不太爽。
4. 有人反映到中国网站的速度等等
5. 据说Sympatico的客户服务不是一般差，虽然Rogers也不怎么样，但是从技术角度来说：Rogers Cable Internet的技术成熟，问题少。
6. 据说Sympatico收费按照整月计算，如果提前一些日子终止还是按照整月收费，而Rogers可以按天数折算。
7. 总体感觉BELL公司的商业信誉差，官僚主义作风深入骨髓，其无耻及无赖程度超过Rogers.

说得不对，别砸我
我用Rogers时间也不短，现在用的是Sympatico(主要是我的Cable不是数字化的，不能用)。我的感觉如下：
速度：似乎还是Sympatico快点，现在到中国网站快不少了。最主要的是很多地点Rogers限制上传数据的数量。
稳定：我这里是Sympatico稳定，从来也没有出事。rogers则断了不止一次。
价格：Sympatico是48.9一个月(tax included)，rogers似乎贵上一块钱。
服务：Sympatico由于稳定，我只是上次DSL Modem给打坏的时候打过一次交到，还行，和Rogers半斤八两。

Question: Why does Sympatico block all SMTP servers except its own? (Port 25 blocking) (#8457)
Answer: Sympatico blocks all traffic (incoming and outgoing) through port 25, except for it's own SMTP servers. The main reason that Sympatico does this is to avoid being being blacklisted for spam (junk e-mail). Here's why:
A common feature of SMTP servers is open-relaying. Open-relaying allows anybody on the internet to relay an email message through an SMTP server. The disadvantage of open-relaying is that it makes all messages appear to originate from the relaying server. For this reason, open-relaying is usually disabled because a spammer could use an SMTP server with an open-relay to send spam, and it would appear that the owner of the SMTP server is sending the spam instead of the spammer. This makes it very difficult to trace the origin of the spam and stop it.
If a Sympatico customer were to operate their own SMTP server, it is possible that it may be configured improperly with open-relaying enabled, and have spam relayed through it. In this situation, it appears that a Sympatico customer is sending the spam. So Sympatico avoids this situation by ensuring that no customer can operate their own SMTP server, and blocking port 25 effectively does just that.
One of the disadvantages of this arrangement is that it also prevents the use of any SMTP server other than the ones that Sympatico provides. So if you have a third-party e-mail provider, you will not be able to send outgoing mail through their SMTP server. You must use a Sympatico SMTP server. Your outgoing mail will still appear with whatever e-mail address you wish, even if it is not a Sympatico e-mail address.
Another disadvantage is that it prevents a Sympatico customer from running their own incoming SMTP e-mail server.
Please note that port 25 blocking does not affect incoming email through POP3 servers, which do not use port 25. You are free to use whatever POP3 provider you wish.
