Actually I'm using POP3, but just looking for improvements in speed. Plus, fetchm,ail doesn't allow fetch more than one account at a time, and it's kind slow in the secure handshaking. There is another package should I "explore" using it to improve speed?

Thanks for your answer

Hi folks

This question is about fetchmail running on my Centos 5.3 box. I need to fetch my email from different accounts living on remote servers and drop it on my local mailbox. The question is wich way is faster for fetchmail... using POP3 or IMAP?

Thanks David

Not sure I could say which is faster, but POP3 is more simple and is intended for what you are doing. IMAP is meant to have all messages stored on the server and thus supports folders and other more advanced features.

Based on what you are trying to accomplish, I would use POP3. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You could probably make different fetchmailrc files for each account you have, and then use the "-f" option to read each separate file. Then launch multiple fetchmail processes for each account. That would allow you to fetch multiple accounts at once.

As for gaining additional speed, it sounds like you may be using the wrong solution to accomplish something that you have not yet explained. High speed is typically not the main goal of email in general.

You can definitely use the -f option to fetchmail. But the neat thing is, you can supply multiple accounts - and multiple local users. For me I supply 2 different pop servers and one local user - works great.

Scott,

You may notice that in the OPs 1st reply that the requirement is to retrieve multiple accounts *at the same time* to increase speed. AFAIK, if you use 1 file with fetchmail it will retrieve messages sequentially from each account.

You can always run multiple copies of fetchmail in the background if you want parallel fetching

or run just one tenth of those RC files (when well numbered) present each time a script is invoked, if you are not in a hurry to retrieve email from side accounts, and want to be kind to the remote pop hosts

Yup, this is my (redacted) fetchmailrc file:

defaults proto pop3 set invisible

poll server1 via mail.server1.net user remote_user1 is localuser1 here fetchall password hahahahaha

poll server2 via pop.server2.com user remote_user2 is localuser2 here fetchall password hahahahaha ssl

poll server3 via mail.server3.net user remote_user3 is localuser3 here fetchall password hahahahahaha

This polls from 3 different servers and stores the results in 3 different mailboxes on my local machine.

% fetchmail fetchmail: No mail for remote_user1 at server1 fetchmail: No mail for remote_user2 at server2 fetchmail: No mail for remote_user3 at server3
