comment Linux VPS settings to allow $_SERVER['REMOTE_ADDR'] to get client ip
contact your VPS provider. It is entirely possible that you are behind some sort of Load Balancer/proxy. as opposed to being directly connected to the internet. They should be able to tell you the config. without this information it will be very hard for us to figure out how to help. since the problem is most likely upstream from you..

comment Transitioning from a POP only email account to new IMAP enabled account - how can subsequent emails to the old POP only email be supported?
Only issue with multiple devices simultaneously accessing pop3 accounts. is that depending upon the backend storage mechanism there could be file locking issues. If the SP doesn't offer IMAP as indicated by OP, it is likely that they are using something like MBOX files and locking is going to be bad with multiple accounts accessing it concurrently.

comment Can I have a DNS wildcard binding in multiple servers?
client cache servers (unless they are doing some add negative caching) should be pretty quick to pick up new record. You could be looking at propagation delays between your primary and secondary authoratative servers. For example you add it to NS1, and it takes a bit to get to ns2 (I don't know how many auth servers you have). but the client then asks for the url and it hits n2 which doesn't have the records yet. Does your NS infrastructure support NOTIFY for zone updates to propagate? are they your NS servers are they hosted by someone else?

comment E-mail always send to spam folder
Every little bit helps. So adding DKIM can help especially with delivery to yahoo. But it can be annoying to setup and get the selectors right especially if you are hosting multiple domains and want to sign each with differnet keys. There are many reasons things get thrown in the spam folder. From content to server rep to combinations of both. My normal response is your hotmail account is worth how much you pay for it ;)

comment Can I have a DNS wildcard binding in multiple servers?
Well, creating an A or CNAME takes about as long as creating a website/host headers in IIS, and both can be scripted. Load balancers to a big cluster of machines that all server everything are one solution to the problem, guess it depends on budget, since good load balancers generally speaking are not cheap..

This is called poor mans load balancing. The DNS Server will return the A records in Random Order, and the client will pick one and go to that. If one of the servers is down 50% of your inbound requests will fail.

comment How to use SSH for web application login?
what operating system? You should be able to use something like Auth_pam to auth against the passwd DB for http_basic auth, or are you implementing your own auth?. You will not be able to use their private key to login. Also if you go down this way make sure to implement rate limiting so $BAD_GUYS cannot just sit and try to crack accounts this way.

comment Our exchange server is sending out a lot of spam
look at the bounces, and look at the auth log, If you allow Auth, it is quite possible one of your users has had their Auth Credentials stolen, and being abused. Or it could be that you are getting tons of incoming to invalid recipients. and exchange is accepting and the bouncing to the envelope sender so you are a blowback source. looking at the DSN might help

comment Can't stop DDOS
So basically time to find a new provider. The hardware firewall will not help. 100%, If you have a 1gb/s connection, all that will do is push the attack to the firewall, and fill that pipe. block 53, and maybe ride it out?

comment Apache2 server stops responding
when it stops responding, do a netstat -an | grep 80 and see if you have tons of requests. I'm wondering if is just drawing enough traffic / or an attack that is starving it of resources, since you say the process is still running (just not answering requests)

comment Mail Service requires reboot every few days
Look in the logs and see why the sasl service is failing. how is postfix configured, are you running a separate auth service (Such as cyrus-sasl). Try restarting that service and see if the problem clears. My guess is a dependent service is failing hence the reason restarting mail server doesn't fix it , but reboot does

comment Cannot connect to remote port 465
have you contacted the vps provider? my guess is they they have a filter blocking all sorts of outbound smtp? Are 25 and 587 blocked outbound. Try installing tcptraceroute and tcptraceroute to port 465 and see where it dies.
