[Dovecot] problem about pop3 using dovecot
I upgraded dovecot from 1.1 to 2.1.8 pop3/imap works but i have a problem. i use pop3 protocol on outlook 2010 for my account. and i set keep my mails on the server for 5 days or until i delete them. These settings were working old dovecot1.1. But when i upgraded it to 2.1.8. if i even delete a mail from outlook the server doesn't delete or old mails are not deleted. what can be the problem ? thanks -- View this message in context: http://dovecot.2317879.n4.nabble.com/problem-about-pop3-using-dovecot-tp37394.html Sent from the Dovecot mailing list archive at Nabble.com.

Re: [Dovecot] about postlogin in dovecot2
My purpose is to restrict a particular email address 's reach for dovecot
services such as pop3/imap.
how can i restrict a particular email address by tcp port ?
I want a particular mail address to be forced to use pop3s/imaps.
I use vpopmail / dovecot2.
How can i do a script for that ?
cat auth-vpopmail.conf.ext
passdb {
driver = vpopmail
args = webmail=127.0.0.1
}
userdb {
driver = vpopmail
args = quota_template=quota_rule=*:backend=%q
}
