hi i use argosoft.net latest build , ewall , and paranoid for a long time . After upgrading from pro to .net i can not send properly email to 2 domains the first one domains@e-center.gr informed me that they have recieved 10 times the email i have send them the second one vasiliki@sisma.gr on the email the argosoft send me has this (This server requires PTR for unauthenticated connections) (please notice that i send every day to different reciepients emails with no issues at all in domains like hotmail.com yahoo.com sssolutions.com cisco.com and so on) Is it possible that i need something more in my setup? 1.I isntalled today ewall eWall LSP because i found in the net that if you use a proxy the reciepient server may reject you if does not recieve the exact ip adress? 2. dont use spf records in my argosoft maybe this is the problem if yes is ther a tutorial on how to create them and ad them in argosoft or ewall? 3.Does this have to do with a security setting that i must enable in argosoft so that i can send them properly the emails? This is the message i get from the when i send to them email But is it possible to send email on large greek isps and companies like cisco and not on the following 2 domains? please help i am confused -----------------------error 1 mail ------------------------------------------------- Mail cannot be delivered to the following recipient(s): domains@e-center.gr Reason: Number of allowed attempts exceeded Delivery history: [DLVR 001265 16-10-08 18:37:26] Delivering item 3639 [DLVR 001265 16-10-08 18:37:26] Resolving MX records for domain e-center.gr [DLVR 001265 16-10-08 18:37:26] Retrieved 1 MX records for domain e-center.gr [DLVR 001265 16-10-08 18:37:26] Delivering mail to 1 recipient(s) at domain e-center.gr using exchanger e-center.gr.

I see a couple of issues right off the top. 1. Reverse Pointer -- Many sites require a reverse pointer (PTR) record of your IP address. In Server Options -> Local Host enter a FQDN (Fully Qualified Domain Name), an example would be yourdomainname.com. Your Domain Name IP should have a reverse lookup. To Check, go to the Command Prompt type the following (in the example below I used my IP address: C:\>nslookup > set type=ptr >216.179.41.21 Non-authoritative answer: 27.41.179.216.in-addr.arpa name = ip216-179-41-27.cust.bestweb.net > If you have a reverse IP then you will get a result something like this. If you do not have one, then you will need to contact your ISP to have them update your DNS record and add the reverse. The other thing you will need is an SPF record. This is also added to your DNS Record as a text record. In the library section is some links for SPF wizards and tools that will help you create one.

Mail Server v1.0.8.3

Added support of STARTTLS (STLS) command for SMTP, POP3, IMAP, and SMTP relay and delivery, which will allow secure, fully encrypted connections, when possible;

11/6/2011 1:10:34 PM

Mail Server v1.0.8.2

Optimized delivery speed. In earlier versions each "tick" which was checking whether messages were in the outbox queue, was picking up only one message at a time. Now it will attempt to pick MaximumAllowedThreads-ActiveDelivery threads messages, which should considerably increase deliver speed;
Optimized SEARCH and STATUS IMAP commands. They appear to be used very extensively by Android, and (not that extensively, but still) by iPhone. Now users who use mobile phones to access their IMAP accounts will see considerable improvement;
Optimized STORE IMAP command. Before storing of IMAP flags was occuring one message at a time, which seemed to be fine with SQL server, but proved to be slow for SQLite... Now it happens with single SQL call.

10/8/2011 7:59:35 PM

ArGoSoft Mail Server v1.0.8.1

Fixed a bug: when using IMAP via Firefox with "When I delete a message, move it to Trash folder" option, marking messages in the trash folder was causing high CPU usage, and was taking some time, making the server pretty much non-responsive. The problem was happening only when using SQLite.

6/6/2011 9:33:36 PM

ArGoSoft Mail Server v1.0.8.0

Fixed a problem with web interface - was showing only first page of messages, and would not switch to other pages; In order to fix the web interface, mail server itself has to be updated;
When installint initially, was still using SQLite, even when SQL was requested;
There was a problem with switching from SQLite database engine to SQL server database engine: the SQL database was not being created;

5/23/2011 5:53:55 PM

ArGoSoft Mail Server .NET v1.0.7.9

The server no longer requires Microsoft SQL Server. If SQL server is not found, it will use SQLite engine, which does not require separate installation. If SQL server is found, then user will be prompted whether he wants to use it;
Made other improvements, such as, now mailbox rebuild indexes orphaned records, rather then deleting them, also added an opotion to increment UIDL validity of folder (both on the Mailbox viewer box);
Made minor improvements on web interface;
