From: Jack2 on 30 May 2010 06:50 Is it possible to get pop connector in sbs03 to retrive emails in 1 minute rather than 15 minutes. What is the reason that minium is 15 minutes.
From: Cliff Galiher - MVP on 30 May 2010 07:04 POP3 as a protocol was never meant to be used between servers. Many ISPs won't let you query a server much more often than that because of the network overhead it incurs and, along with some security concerns (passwords are sent in clear text by default, for example), querying too often can get your ISP to lock you out, slow down your server if there are multiple mailboxes, and increases the chance that someone can sniff out your ISP passwords. If you want faster email delivery, look at moving to SMTP. The pop3 connector is a tool to help new SBS installations migrate from ISP-stored emails to in-house email, but should not be used as a long-term solution. -- Cliff Galiher Microsoft has opened the Small Business Server forum on Technet!

From: Merv Porter [SBS-MVP] on 30 May 2010 07:41 Is it possible - yes, IIRC, there is a registry hack to reduce the interval to less than 15 minutes. Is it advisable - probably not. If the POP3 Manager is downloading mail when another POP3 download event is triggered, there is a potential for things to go pear-shaped. That said, there are also 3rd party POP3 retrieval products that will allow you to set the interval to less than 15 minutes. .... plus, what Cliff said about lock outs from your ISP. -- Merv Porter [SBS-MVP] ============================ "Jack2" <Jack2(a)discussions.microsoft.com> wrote in message news:A367B539-B71B-40E2-88A9-2866EAD9478B(a)microsoft.com... > Is it possible to get pop connector in sbs03 to retrive emails in 1 minute > rather than 15 minutes.

From: Russ SBITS.Biz [SBS-MVP] on 30 May 2010 23:03 Along with the other reasons mentioned You can have Duplication of messages and in some cases Delayed Messages. (if they are large.) Change your MX Records Open up Port 25 and don't use the POP3 at all Easier, and it works.. And you are not passing everyone's passwords in PLAIN Text over the WAN (Like you are with POP3) Russ -- Russell Grover - SBITS.Biz [SBS-MVP] MCP, MCPS, MCNPS, SBSC Remote Small Business Server/Computer Support - www.SBITS.Biz BPOS - Microsoft Online Services - www.Microsoft-Online-Services.com "Jack2" <Jack2(a)discussions.microsoft.com> wrote in message news:A367B539-B71B-40E2-88A9-2866EAD9478B(a)microsoft.com... > Is it possible to get pop connector in sbs03 to retrive emails in 1 minute > rather than 15 minutes.

And not sure Ive ever seen anyone hack the Internet backbone to get someones POP password. If it were an issue millions of Outlook Express/Windows Mail/Eudora etc. users would have been in trouble some time ago. "Many ISPs won't let you query a server much more often than that because of the network overhead it incurs.." I've never seen this in a decade - but which ISPs are these that you know of? By default stand alone Outlook collects every 5 minutes and Ive never seen any issue there and its the exact same POP mechanism as the POP3 connector. An ISPs 'stand alone' POP users will number thousands more than those using a POP connector in SBS so dont see how this would be an issue. |
