Mar 31, 2010My actual mail is via pop3 from verizon. What I've done so far is just pull my pop3 mail onto my main machine at my house. But I'm finding I'd rather have a single imap server on my network so then all my machines could see the same mail.
I don't really want the imap server to poll verizon for mail, I just want the imap server to check pop3 mail at verizon only when one of my mail apps checks into it to look for mail.

Ubuntu Security :: Restrict Users Password Changing To Themself
May 11, 2010I want the users to access servers via ssh public key only. By default they don't know their initial password and do need to change that when performing administrative tasks.For changing their passwords without knowing the old they need to switch to root for this special case.The only case it seems I don't have control is that users can not only change their password but also the password of other peoples. Does someone sees a solution (without apparmor/selinux and special /usr/bin/passwd.sh) to restrict users to only change their password?I miss the feature of using environment variables in sudoers file.

View 5 Replies View RelatedUbuntu :: Setting Up Gmail In Evolution: Imap Or Pop3?
Jan 26, 2011I'm trying to set up my gmail account with Evolution. I am trying to set up a mail client where -
1) All the mails are stored locally, so that I can work offline. When I reconnect, the client (Evolution) syncs with the server - sends emails and updates any changes.
2) All the labels/folder system to be respected and retained.
After struggling with various sites that argued Pop3 and IMAP (numerous blogs and google searches), I came across this conclusion (pls correct them if they are wrong)-
1) Pop3 allows mails to be stored locally, but will not break them up into folders.
2) IMAP will allow the folder system, but will only store the headers of mail on the local server, and the content will be downloaded as per request.
1) Will Pop3 access allow syncing between the local version and the server version? For instance, a mail read in Evolution should be marked as read when I sign into the web-interface as well.(I can always create a filter/rule that replicates gmail filters)
2) Will IMAP allow me to store all mail locally (isn't this exactly what IMAP is not!)? The combination of imap-gmail-evolution was not so successful when I tried it out - too slow!
PS: I would prefer Evolution over Thunderbird so that I can integrate the Calendar. However, if ThunderBird is the easiest solution, then it's fine too...
Ubuntu Networking :: Can't POP3 - IMAP Into Gmail / Enable This?
Aug 7, 2011I'm trying to connect to Gmail to pull my emails from the Gmail site, via the IMAP/POP3 access server. However, I can't seem to connect to the server when in Ubuntu code...
And it hangs here indefinitely. However, if I reboot my PC into Windows, it connects fine. I've turned off UFW so I would expect the connection to work. I've also been able to POP3 into other servers, so it seems to be something specific to the gmail IP.
Anyone else had the same problem or know how I can debug/fix this?
Server :: Limiting POP3/IMAP Access Frequency?
Sep 24, 2010My server listens to POP3/IMAP requests. Some users have configured their mailers with high checking frequencies, say once every minute, such that the system logs are full of entries with no significance at all.I'd like to ask if there is a way to limit the per IP frequency of POP3/IMAP access ?I'm using "xinetd" to wrap the "ipop3d" and "imapd" which come with the Alpine package.
View 4 Replies View RelatedUbuntu Servers :: Configure A POP3 / IMAP Proxy Server?
Jan 25, 2011This is my first post to the forum
I've recently migrated my office PCs to ubuntu. My server doesn't server any big purpose but to provide Internet Connection to the rest of the nodes. Things were quite easier during the windows era using ICS.
Even in Ubuntu we were able to do it using the "shared network" option, simple & straight forward. But things got complicated only after installing "squid". Needless to say it brought in a lot of add ons as far as the http proxy serving is concerned & we are enjoying a better internet(http only) connectivity without any doubt. But we are not able to use our email clients, MS Outlook or Thunderbird
But to best of my knowledge squid strictly is a http proxy hence doesn't support handling requests on ports other than 80. (465 & 995 in my case)
Now I have two queries, 1. Can "Squid" really be used to do what I want here??? using iptables, port forwarding or any other mean
& 2. Can any one suggest a good pop3/imap proxy as good as squid is.
Ubuntu :: Retrieve Email By POP3 Via IMAP To Home Server?
Feb 16, 2011I want to retrieve emails from my POP3 servers to my home server. But from there, I want to be able to access them via IMAP from my other computers, i.e. desktop, laptop, phone. And then of course I want to be able to send emails from said devices via IMAP to my home server which POP3's them out to my mail servers. Basically, I have a few POP3 accounts with various hosts and I want to conveniently interact with them from lots of devices using my preferred software (i.e. Mutt, or Thunderbird on my Windows boxes). My home server is Ubuntu Server if that's relevant.

General :: Setup A Functioning Imap And Pop3 Mail Server Using Dovecot-postfix?
May 4, 2010I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.
However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.

Sep 23, 2010I have a Suse11 box with 2 network cards:
I have squid as a proxy on the Suse box, and with the default firewall I have to enable masquerading to allow clients on the eth3:1-3 to send and receive mail through the Suse box. I found the Suse firewall completely inadequate (all P2P software/connections are allowed once you enable masquerading) and had to install ConfigServer Security & Firewall. In die configuration of csf I could get my way around getting smtp to work for the eth3:1-3 clients, but pop3 connections does not go through the box. I know I need to allow port 110 and 995 to masquerade of NAT (or something) and then the same for port 22
