RE: email pop3 question
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of David Banning Sent: Wednesday, March 12, 2008 12:49 PM To: [EMAIL PROTECTED] Subject: email pop3 question I am using dovecot email on my server - Users can connect via IMAP or POP3. I have a user who is using pop3 but not removing the email from the server - so the email stays on the server, -and- it is collecting on their computer - as the emails build up, will there be a problem with this? For IMAP it stays on the server, so I assume the server will not be presented with any problem - but will the user suffer any problem eventually? It depends on a lot of variables. For example, I have a 64-bit mailserver running uw-imapd. I have a 500MB mailbox with around 16,000 e-mail messages in it. When I connect with Outlook, it takes about a minute for the server and client to sync with each other. Beyond that, it's not even noticable. However, some of the webmail clients do have a lot of problems with this large of a mailbox. With POP3 you start having problems with more than a couple hundred messages in the inbox.

The assumption that just because the user is using IMAP will alleviate any problems isn't necessarily true. I'd suggest getting over to the dovecot mailling lists and asking them specifically the same question. I don't use dovecot exclusively where I work, but generally when there is a problem, it's because of a user having way too much email. Whether the user keeps their mail on the server via pop or uses imap exclusively, the majority of the time it takes to grab headers and/or parse through all the emails is limited by disk. It's not uncommon for some of our users to have 4000+ emails in their inbox, and it's not uncommon for me to tell them why their pop/imap client is slow. ~Paul ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have a user who is using pop3 but not removing the email from the server - so the email stays on the server, -and- it is collecting on their computer - as the emails build up, will there be a problem with this? Probably not. But it suggests to me that the user has probably misconfigured his pop client to not delete email after he's picked it up. Unless, he's using some peculiar kind of back-up strategy! For IMAP it stays on the server, so I assume the server will not be presented with any problem - but will the user suffer any problem eventually? He could do. The pop3 protocol is painfully slow and deleting thousands of emails that have built up is no fun. You have to write a script that deletes them one by one unless dovecot supports a delete all mode for pop3. You might want to drop them an email to tell them that their email isn't being deleted after collection. Here's a script for deleting them, if he wants it: #!/usr/local/bin/ksh # # Deletes mail off pop3 server # # Usage: e.g: Clear 3000 emails: # #$ clean_pop3 3000 | telnet popserver.net 110 username=user; password=pass; MAX_MESS=$1 [ $# -eq 0 ] exit 1 || : sleep 2 echo USER $username sleep 1 echo PASS $password sleep 2 while [[ $MAX_MESS -gt 0 ]] do echo DELE $MAX_MESS sleep 1 (( MAX_MESS -= 1 )) done sleep 2 echo QUIT sleep 2 -- Frank Contact info: http://www.shute.org.uk/misc/contact.html ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
